checkout test: further ensure workdir perms are updated
When both the index _and_ the working directory has changed
permissions on a file permissions on a file - but only the permissions,
such that the contents of the file are identical - ensure that

diff_tform: fix rename detection with rewrite/delete pair
A rewritten file can either be classified as a modification of its
contents or of a delete of the complete file followed by an addition of
the new content. This distinction becomes important when we want to
detect renames for rewrites. Given a scenario where a file "a" has been
deleted and another file "b" has been renamed to "a", this should be
detected as a deletion of "a" followed by a rename of "a" -> "b". Thus,
splitting of the original rewrite into a delete/add pair is important
here.
This splitting is represented by a flag we can set at the current delta.
While the flag is already being set in case we want to break rewrites,
we do not do so in case where the `GIT_DIFF_FIND_RENAMES_FROM_REWRITES`
flag is set. This can trigger an assert when we try to match the source
and target deltas.
Fix the issue by setting the `GIT_DIFF_FLAG__TO_SPLIT` flag at the delta
when it is a rename target and `GIT_DIFF_FIND_RENAMES_FROM_REWRITES` is
set.

tests: add rename-rewrite scenarios to "renames" repository
Add two more scenarios to the "renames" repository. The first scenario
has a major rewrite of a file and a delete of another file, the second
scenario has a deletion of a file and rename of another file to the
deleted file. Both scenarios will be used in the following commit.

tests: diff::rename: use defines for commit OIDs
While we frequently reuse commit OIDs throughout the file, we do not
have any constants to refer to these commits. Make this a bit easier to
read by giving the commit OIDs somewhat descriptive names of what kind
of commit they refer to.

checkout: take mode into account when comparing index to baseline
When checking out a file, we determine whether the baseline (what we
expect to be in the working directory) actually matches the contents
of the working directory. This is safe behavior to prevent us from
overwriting changes in the working directory.
We look at the index to optimize this test: if we know that the index
matches the working directory, then we can simply look at the index
data compared to the baseline.
We have historically compared the baseline to the index entry by oid.
However, we must also compare the mode of the two items to ensure that
they are identical. Otherwise, we will refuse to update the working
directory for a mode change.

tests: index::filemodes: fix use of uninitialized memory
The new index entry structure was not being initialized to all-zeroes.
As that structure is used to add a new entry to the current index, and
the hashing algorithm of the index making use of the uninitialized flags
to calculate the state, we might miscompute the hash of the entry and
add it at the wrong position. Later lookups would then fail.
Initialize the structure with `memset` to fix the test breaking on some
platforms.

git_index_add_frombuffer: only accept files/links
Ensure that the buffer given to `git_index_add_frombuffer` represents a
regular blob, an executable blob, or a link. Explicitly reject commit
entries (submodules) - it makes little sense to allow users to add a
submodule from a string; there's no possible path to success.

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.

util: clean up header includes
While "util.h" declares the macro `git__tolower`, which simply resorts
to tolower(3P) on Unix-like systems, the <ctype.h> header is only being
included in "util.c". Thus, anybody who has included "util.h" without
having <ctype.h> included will fail to compile as soon as the macro is
in use.
Furthermore, we can clean up additional includes in "util.c" and simply
replace them with an include for "common.h".

index: shut up warning on uninitialized variable
Even though the `entry` variable will always be initialized when
`read_entry` returns success and even though we never dereference
`entry` in case `read_entry` fails, GCC prints a warning about
uninitialized use. Just initialize the pointer to `NULL` in order to
shut GCC up.

CMakeLists: increase strict aliasing level to 3
The strict aliasing rules disallow dereferencing the pointer to a
variable of a certain type as another type, which is frequently used
e.g. when casting structs to their base type. We currently have the
warning level for strict aliasing rules set to `2`, which is described
by gcc(1) as being "Aggressive, quick, not too precise." And in fact, we
experience quite a lot of warnings when doing a release build due to
that.
GCC provides multiple levels, where higher levels are more accurate, but
also slower due to the additional analysis required. Still, we want to
have warning level 3 instead of 2 to avoid the current warnings we have
in the Travis CI release builds. As this is the default warning level
when no level is passed to `-Wstrict-aliasing`, we can just remove the
level and use that default.

streams: openssl: fix use of uninitialized variable
When verifying the server certificate, we do try to make sure that the
hostname actually matches the certificate alternative names. In cases
where the host is either an IPv4 or IPv6 address, we have to compare the
binary representations of the hostname with the declared IP address of
the certificate. We only do that comparison in case we were successfully
able to parse the hostname as an IP, which would always result in the
memory region being initialized. Still, GCC 6.4.0 was complaining about
usage of non-initialized memory.
Fix the issue by simply asserting that `addr` needs to be initialized.
This shuts up the GCC warning.

buf_text: remove `offset` parameter of BOM detection function
The function to detect a BOM takes an offset where it shall look for a
BOM. No caller uses that, and searching for the BOM in the middle of a
buffer seems to be very unlikely, as a BOM should only ever exist at
file start.
Remove the parameter, as it has already caused confusion due to its
weirdness.

config_parse: fix reading files with BOM
The function `skip_bom` is being used to detect and skip BOM marks
previously to parsing a configuration file. To do so, it simply uses
`git_buf_text_detect_bom`. But since the refactoring to use the parser
interface in commit 9e66590bd (config_parse: use common parser
interface, 2017-07-21), the BOM detection was actually broken.
The issue stems from a misunderstanding of `git_buf_text_detect_bom`. It
was assumed that its third parameter limits the length of the character
sequence that is to be analyzed, while in fact it was an offset at which
we want to detect the BOM. Fix the parameter to be `0` instead of the
buffer length, as we always want to check the beginning of the
configuration file.

config_parse: handle empty lines with CRLF

regression in the future.

config_parse: add comment to clarify logic getting next character

rather odd and doesn't immediately convey this meaning, so add a comment
to clarify what happens.

merge: virtual commit should be last argument to merge-base
Our virtual commit must be the last argument to merge-base: since our
algorithm pushes _both_ parents of the virtual commit, it needs to be
the last argument, since merge-base:
> Given three commits A, B and C, git merge-base A B C will compute the
> merge base between A and a hypothetical commit M
We want to calculate the merge base between the actual commit ("two")
and the virtual commit ("one") - since one actually pushes its parents
to the merge-base calculation, we need to calculate the merge base of
"two" and the parents of one.

merge: reverse merge bases for recursive merge
When the commits being merged have multiple merge bases, reverse the
order when creating the virtual merge base. This is for compatibility
with git's merge-recursive algorithm, and ensures that we build
identical trees.
Git does this to try to use older merge bases first. Per 8918b0c:
> It seems to be the only sane way to do it: when a two-head merge is
> done, and the merge-base and one of the two branches agree, the
> merge assumes that the other branch has something new.
>
> If we start creating virtual commits from newer merge-bases, and go
> back to older merge-bases, and then merge with newer commits again,
> chances are that a patch is lost, _because_ the merge-base and the
> head agree on it. Unlikely, yes, but it happened to me.

sysdir: do not use environment in setuid case
In order to derive the location of some Git directories, we currently
use the environment variables $HOME and $XDG_CONFIG_HOME. This might
prove to be problematic whenever the binary is run with setuid, that is
when the effective user does not equal the real user. In case the
environment variables do not get sanitized by the caller, we thus might
end up using the real user's configuration when doing stuff as the
effective user.
The fix is to use the passwd entry's directory instead of $HOME in this
situation. As this might break scenarios where the user explicitly sets
$HOME to another path, this fix is only applied in case the effective
user does not equal the real user.

odb: loose object streaming for packlike loose objects
A "packlike" loose object was a briefly lived loose object format where
the type and size were encoded in uncompressed space at the beginning of
the file, followed by the compressed object contents. Handle these in a
streaming manner as well.

odb_loose: test reading a large file in stream
Since some test situations may have generous disk space, but limited RAM
(eg hosted build agents), test that we can stream a large file into a
loose object, and then stream it out of the loose object storage.

odb: provide length and type with streaming read
The streaming read functionality should provide the length and the type
of the object, like the normal read functionality does.

odb_loose: stream -> writestream
There are two streaming functions; one for reading, one for writing.
Disambiguate function names between `stream` and `writestream` to make
allowances for a read stream.

attr: avoid stat'ting files for bare repositories
Depending on whether the path we want to look up an attribute for is a
file or a directory, the fnmatch function will be called with different
flags. Because of this, we have to first stat(3) the path to determine
whether it is a file or directory in `git_attr_path__init`. This is
wasteful though in bare repositories, where we can already be assured
that the path will never exist at all due to there being no worktree. In
this case, we will execute an unnecessary syscall, which might be
noticeable on networked file systems.
What happens right now is that we always pass the `GIT_DIR_FLAG_UNKOWN`
flag to `git_attr_path__init`, which causes it to `stat` the file itself
to determine its type. As it is calling `git_path_isdir` on the path,
which will always return `false` in case the path does not exist, we end
up with the path always being treated as a file in case of a bare
repository. As such, we can just check the bare-repository case in all
callers and then pass in `GIT_DIR_FLAG_FALSE` ourselves, avoiding the
need to `stat`. While this may not always be correct, it at least is no
different from our current behavior.

odb: reject reading and writing null OIDs
The null OID (hash with all zeroes) indicates a missing object in
upstream git and is thus not a valid object ID. Add defensive
measurements to avoid writing such a hash to the object database in the
very unlikely case where some data results in the null OID. Furthermore,
add shortcuts when reading the null OID from the ODB to avoid ever
returning an object when a faulty repository may contain the null OID.

tree: reject writing null-OID entries to a tree
In commit a96d3cc3f (cache-tree: reject entries with null sha1,
2017-04-21), the git.git project has changed its stance on null OIDs in
tree objects. Previously, null OIDs were accepted in tree entries to
help tools repair broken history. This resulted in some problems though
in that many code paths mistakenly passed null OIDs to be added to a
tree, which was not properly detected.
Align our own code base according to the upstream change and reject
writing tree entries early when the OID is all-zero.
