str: introduce `git_str` for internal, `git_buf` is external
libgit2 has two distinct requirements that were previously solved by
`git_buf`. We require:
1. A general purpose string class that provides a number of utility APIs
for manipulating data (eg, concatenating, truncating, etc).
2. A structure that we can use to return strings to callers that they
can take ownership of.
By using a single class (`git_buf`) for both of these purposes, we have
confused the API to the point that refactorings are difficult and
reasoning about correctness is also difficult.
Move the utility class `git_buf` to be called `git_str`: this represents
its general purpose, as an internal string buffer class. The name also
is an homage to Junio Hamano ("gitstr").
The public API remains `git_buf`, and has a much smaller footprint. It
is generally only used as an "out" param with strict requirements that
follow the documentation. (Exceptions exist for some legacy APIs to
avoid breaking callers unnecessarily.)
Utility functions exist to convert a user-specified `git_buf` to a
`git_str` so that we can call internal functions, then converting it
back again.

utf8: refactor utf8 functions
Move the utf8 functions into a proper namespace `git_utf8` instead of
being in the namespaceless `git__` function group. Update them to

our API treating strings as `char *` (even if they truly contain `uchar`s
inside).

Make git__strntol64() ~70%* faster
This change uses compiler intrinsics to detect overflows instead of
using divisions to detect potential overflow. This makes the code faster
and makes it easier to read as a bonus side-effect!
Some of the things this quickens:
* Config parsing.
* Tree parsing.
* Smart protocol negotiation.
\* Measured by running `libgit2_clar` with `-fno-optimize-sibling-calls
-fno-omit-frame-pointer` under `perf(1)`:
```shell
$ perf diff --symbols=git__strntol64 --compute=ratio \
--percentage=absolute baseline.data perf.data
\# Event 'cycles'

\# Baseline Ratio Shared Object
\# ........ .............. .............

util: do not perform allocations in insertsort
Our hand-rolled fallback sorting function `git__insertsort_r` does an
in-place sort of the given array. As elements may not necessarily be
pointers, it needs a way of swapping two values of arbitrary size, which
is currently implemented by allocating a temporary buffer of the
element's size. This is problematic, though, as the emulated `qsort`
interface doesn't provide any return values and thus cannot signal an
error if allocation of that temporary buffer has failed.
Convert the function to swap via a temporary buffer allocated on the
stack. Like this, it can `memcpy` contents of both elements in small
batches without requiring a heap allocation. The buffer size has been
chosen such that in most cases, a single iteration of copying will
suffice. Most importantly, it can fully contain `git_oid` structures and
pointers.
Add a bunch of tests for the `git__qsort_r` interface to verify nothing
breaks. Furthermore, this removes the declaration of `git__insertsort_r`
and makes it static as it is not used anywhere else.

utf8: use size_t for length of buffer
The `git__utf8_charlen` now takes `size_t` as the buffer length, since
it contains the full length of the buffer at the current position. It
now returns `-1` in all cases where utf8 codepoints are invalid, since
callers only care about a valid length of a sequence of codepoints, or
if the current position is not valid utf8.

strntol: fix out-of-bounds reads when parsing numbers with leading sign
When parsing a number, we accept a leading plus or minus sign to return
a positive or negative number. When the parsed string has such a leading
sign, we set up a flag indicating that the number is negative and
advance the pointer to the next character in that string. This misses
updating the number of bytes in the string, though, which is why the
parser may later on do an out-of-bounds read.
Fix the issue by correctly updating both the pointer and the number of
remaining bytes. Furthermore, we need to check whether we actually have
any bytes left after having advanced the pointer, as otherwise the
auto-detection of the base may do an out-of-bonuds access. Add a test
that detects the out-of-bound read.
Note that this is not actually security critical. While there are a lot
of places where the function is called, all of these places are guarded
or irrelevant:
- commit list: this operates on objects from the ODB, which are always
NUL terminated any may thus not trigger the off-by-one OOB read.
- config: the configuration is NUL terminated.
- curl stream: user input is being parsed that is always NUL terminated
- index: the index is read via `git_futils_readbuffer`, which always NUL
terminates it.
- loose objects: used to parse the length from the object's header. As
we check previously that the buffer contains a NUL byte, this is safe.
- rebase: this parses numbers from the rebase instruction sheet. As the
rebase code uses `git_futils_readbuffer`, the buffer is always NUL
terminated.
- revparse: this parses a user provided buffer that is NUL terminated.
- signature: this parser the header information of objects. As objects
read from the ODB are always NUL terminated, this is a non-issue. The
constructor `git_signature_from_buffer` does not accept a length
parameter for the buffer, so the buffer needs to be NUL terminated, as
well.
- smart transport: the buffer that is parsed is NUL terminated
- tree cache: this parses the tree cache from the index extension. The
index itself is read via `git_futils_readbuffer`, which always NUL
terminates it.
- winhttp transport: user input is being parsed that is always NUL
terminated

strntol: fix detection and skipping of base prefixes
The `git__strntol` family of functions has the ability to auto-detect
a number's base if the string has either the common '0x' prefix for
hexadecimal numbers or '0' prefix for octal numbers. The detection of
such prefixes and following handling has two major issues though that are
being fixed in one go now.
- We do not do any bounds checking previous to verifying the '0x' base.
While we do verify that there is at least one digit available
previously, we fail to verify that there are two digits available and
thus may do an out-of-bounds read when parsing this
two-character-prefix.
- When skipping the prefix of such numbers, we only update the pointer
length without also updating the number of remaining bytes. Thus if we
try to parse a number '0x1' of total length 3, we will first skip the
first two bytes and then try to read 3 bytes starting at '1'.
Fix both issues by disentangling the logic. Instead of doing the
detection and skipping of such prefixes in one go, we will now first try
to detect the base while also honoring how many bytes are left. Only if
we have a valid base that is either 8 or 16 and have one of the known
prefixes, we will now advance the pointer and update the remaining bytes
in one step.
Add some tests that verify that no out-of-bounds parsing happens and
that autodetection works as advertised.

strntol: fix out-of-bounds read when skipping leading spaces
The `git__strntol` family of functions accepts leading spaces and will
simply skip them. The skipping will not honor the provided buffer's
length, though, which may lead it to read outside of the provided
buffer's bounds if it is not a simple NUL-terminated string.
Furthermore, if leading space is trimmed, the function will further
advance the pointer but not update the number of remaining bytes, which
may also lead to out-of-bounds reads.
Fix the issue by properly paying attention to the buffer length and
updating it when stripping leading whitespace characters. Add a test
that verifies that we won't read past the provided buffer length.

util: provide `git__memmem` function
Unfortunately, neither the `memmem` nor the `strnstr` functions are part
of any C standard but are merely extensions of C that are implemented by
e.g. glibc. Thus, there is no standardized way to search for a string in
a block of memory with a limited size, and using `strstr` is to be
considered unsafe in case where the buffer has not been sanitized. In
fact, there are some uses of `strstr` in exactly that unsafe way in our
codebase.
Provide a new function `git__memmem` that implements the `memmem`
semantics. That is in a given haystack of `n` bytes, search for the
occurrence of a byte sequence of `m` bytes and return a pointer to the
first occurrence. The implementation chosen is the "Not So Naive"
algorithm from [1]. It was chosen as the implementation is comparably
simple while still being reasonably efficient in most cases.
Preprocessing happens in constant time and space, searching has a time
complexity of O(n*m) with a slightly sub-linear average case.

util: fix out of bounds read in error message
When an integer that is parsed with `git__strntol32` is too big to fit
into an int32, we will generate an error message that includes the
actual string that failed to parse. This does not acknowledge the fact
that the string may either not be NUL terminated or alternative include
additional characters after the number that is to be parsed. We may thus
end up printing characters into the buffer that aren't the number or,
worse, read out of bounds.
Fix the issue by utilizing the `endptr` that was set by
`git__strntol64`. This pointer is guaranteed to be set to the first
character following the number, and we can thus use it to compute the
width of the number that shall be printed. Create a test to verify that
we correctly truncate the number.

util: avoid signed integer overflows in `git__strntol64`
While `git__strntol64` tries to detect integer overflows when doing the
necessary arithmetics to come up with the final result, it does the
detection only after the fact. This check thus relies on undefined
behavior of signed integer overflows. Fix this by instead checking
up-front whether the multiplications or additions will overflow.
Note that a detected overflow will not cause us to abort parsing the
current sequence of digits. In the case of an overflow, previous
behavior was to still set up the end pointer correctly to point to the
first character immediately after the currently parsed number. We do not
want to change this now as code may rely on the end pointer being set up
correctly even if the parsed number is too big to be represented as
64 bit integer.

Explicitly mark fallthrough cases with comments
A lot of compilers nowadays generate warnings when there are cases in a
switch statement which implicitly fall through to the next case. To
avoid this warning, the last line in the case that is falling through
can have a comment matching a regular expression, where one possible
comment body would be `/* fall through */`.
An alternative to the comment would be an explicit attribute like e.g.
`[[clang::fallthrough]` or `__attribute__ ((fallthrough))`. But GCC only
introduced support for such an attribute recently with GCC 7. Thus, and
also because the fallthrough comment is supported by most compilers, we
settle for using comments instead.
One shortcoming of that method is that compilers are very strict about
that. Most interestingly, that comment _really_ has to be the last line.
In case a closing brace follows the comment, the heuristic will fail.

Make sure to always include "common.h" first
Next to including several files, our "common.h" header also declares
various macros which are then used throughout the project. As such, we
have to make sure to always include this file first in all
implementation files. Otherwise, we might encounter problems or even
silent behavioural differences due to macros or defines not being
defined as they should be. So in fact, our header and implementation
files should make sure to always include "common.h" first.
This commit does so by establishing a common include pattern. Header
files inside of "src" will now always include "common.h" as its first
other file, separated by a newline from all the other includes to make
it stand out as special. There are two cases for the implementation
files. If they do have a matching header file, they will always include
this one first, leading to "common.h" being transitively included as
first file. If they do not have a matching header file, they instead
include "common.h" as first file themselves.
This fixes the outlined problems and will become our standard practice
for header and source files inside of the "src/" from now on.

These paths would (without \\?\ syntax) be elided to other paths - for

Merge git_buf and git_buffer
This makes the git_buf struct that was used internally into an
externally available structure and eliminates the git_buffer.
As part of that, some of the special cases that arose with the
externally used git_buffer were blended into the git_buf, such as
being careful about git_buf objects that may have a NULL ptr and
allowing for bufs with a valid ptr and size but zero asize as a
way of referring to externally owned data.

util: git__memzero() tweaks
On Linux: fix a warning message related to the volatile qualifier (cast)
On Windows: use SecureZeroMemory()
On both, inline the call, so that no entry point can lead back to this "secure" memory zeroing.

Add safe memset and use it
This adds a `git__memset` routine that will not be optimized away
and updates the places where I memset() right before a free() call
to use it.

Add range checking around cache opts
Add a git_cache_set_max_object_size method that does more checking
around setting the max object size. Also add a git_cache_size to
read the number of objects currently in the cache. This makes it
easier to write tests.

Switch search paths to classic delimited strings
This switches the APIs for setting and getting the global/system
search paths from using git_strarray to using a simple string with
GIT_PATH_LIST_SEPARATOR delimited paths, just as the environment
PATH variable would contain. This makes it simpler to get and set
the value.
I also added code to expand "$PATH" when setting a new value to
embed the old value of the path. This means that I no longer
require separate actions to PREPEND to the value.

Implement global/system file search paths
The goal of this work is to expose the search logic for "global",
"system", and "xdg" files through the git_libgit2_opts() interface.
Behind the scenes, I changed the logic for finding files to have a
notion of a git_strarray that represents a search path and to store
a separate search path for each of the three tiers of config file.
For each tier, I implemented a function to initialize it to default
values (generally based on environment variables), and then general
interfaces to get it, set it, reset it, and prepend new directories
to it.
Next, I exposed these interfaces through the git_libgit2_opts
interface, reusing the GIT_CONFIG_LEVEL_SYSTEM, etc., constants
for the user to control which search path they were modifying.
There are alternative designs for the opts interface / argument
ordering, so I'm putting this phase out for discussion.
Additionally, I ended up doing a little bit of clean up regarding
attr.h and attr_file.h, adding a new attrcache.h so the other two
files wouldn't have to be included in so many places.

Make tree iterator handle icase equivalence
There is a serious bug in the previous tree iterator implementation.
If case insensitivity resulted in member elements being equivalent
to one another, and those member elements were trees, then the
children of the colliding elements would be processed in sequence
instead of in a single flattened list. This meant that the tree
iterator was not truly acting like a case-insensitive list.
This completely reworks the tree iterator to manage lists with
case insensitive equivalence classes and advance through the items
in a unified manner in a single sorted frame.
It is possible that at a future date we might want to update this
to separate the case insensitive and case sensitive tree iterators
so that the case sensitive one could be a minimal amount of code
and the insensitive one would always know what it needed to do
without checking flags.
But there would be so much shared code between the two, that I'm
not sure it that's a win. For now, this gets what we need.
More tests are needed, though.

Add payload "_r" versions of bsearch and tsort
git__bsearch and git__tsort did not pass a payload through to the
comparison function. This makes it impossible to implement sorted
lists where the sort order depends on external data (e.g. building
a secondary sort order for the entries in a tree). This commit
adds git__bsearch_r and git__tsort_r versions that pass a third
parameter to the cmp function of a user payload.

Fix up some missing consts in tree & index
This fixes some missed places where we can apply const-ness to
various public APIs.
There are still some index and tree APIs that cannot take const
pointers because we sort our `git_vectors` lazily and so we can't
reliably bsearch the index and tree content without applying a
`git_vector_sort()` first.
This also fixes some missed places where size_t can be used and
where const can be applied to a couple internal functions.

Fix git_status_file for files that start with a character > 0x7f
git_status_file would always return GIT_ENOTFOUND for these files.
The underlying bug was that git__strcmp_cb, which is used by
git_path_with_stat_cmp to sort entries in the working directory,
compares strings based on unsigned chars (this is confirmed by the
strcmp(3) manpage), while git__prefixcmp, which is used by
workdir_iterator__entry_cmp to search for a path in the working
directory, compares strings based on char. So the sort puts this path at
the end of the list, while the search expects it to be at the beginning.
The fix was simply to make git__prefixcmp compare using unsigned chars,
just like strcmp(3). The rest of the change is just adding/updating
tests.
