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.

Since a625b092c (branch: correctly reject refs/heads/{-dash,HEAD},
2017-11-14), which is included in v2.16.0, upstream git refuses to
create branches which are named HEAD to avoid ambiguity with the
symbolic HEAD reference. Adjust our own code to match that behaviour and
reject creating branches names HEAD.

refs: include " sorted " in our packed-refs header
This lets git know that we do in fact have written our packed-refs file
sorted (which is apparently not necessarily the case) and it can then use the
new-ish mmaped access which lets it avoid significant amounts of effort parsing
potentially large files to get to a single piece of data.

refs: document need to free refs in foreach-callback
References passed to the callback function of `git_reference_foreach`
are expected to be owned by the callback. As such, they are never being
freed by `git_reference_foreach`, but will have to be freed by the
caller. This small detail is never mentioned in the function's
documentation, though, making it easy to get wrong. Document this to
make it discoverable.

cmake: use a FEATURE_SUMMARY call compatible with 3.0.2
When we print features, we make an effort to support all the way back to
pre-3.0. However, in the code for versions from 3 onward we call
`FEATURE_SUMMARY` with multiple kinds of elements to print in the same line.
This is only supported in CMake 3.1 and later, making the rather popular CMake
3.0.2 unable to build the library.
Use a single kind of element per invocation. This means we need to provide a
"description" text, which CMake provides for us if provide multiple kinds of
elements.

cmake: move the rule to find static archives close to building clar
If we're building static libraries, we want to use that for building our clar
binary. This is done in 49551254 (2017-09-22; cmake: use static dependencies
when building static libgit2) but that commit included the rule too early,
making it affect the search for iconv, meaning we did not find it when we were
building a static libgit2.
Move the rule to just before building clar, after we've included the rules for
building the library itself. This lets us find and link to the dynamic libiconv.

`-DSHA1_BACKEND=<BACKEND>` option instead. This completely replaces the
previous auto-selection.

diff_generate: avoid excessive stats of .gitattribute files
When generating a diff between two trees, for each file that is to be
diffed we have to determine whether it shall be treated as text or as
binary files. While git has heuristics to determine which kind of diff
to generate, users can also that default behaviour by setting or
unsetting the 'diff' attribute for specific files.
Because of that, we have to query gitattributes in order to determine
how to diff the current files. Instead of hitting the '.gitattributes'
file every time we need to query an attribute, which can get expensive
especially on networked file systems, we try to cache them instead. This
works perfectly fine for every '.gitattributes' file that is found, but
we hit cache invalidation problems when we determine that an attribuse
file is _not_ existing. We do create an entry in the cache for missing
'.gitattributes' files, but as soon as we hit that file again we
invalidate it and stat it again to see if it has now appeared.
In the case of diffing large trees with each other, this behaviour is
very suboptimal. For each pair of files that is to be diffed, we will
repeatedly query every directory component leading towards their
respective location for an attributes file. This leads to thousands or
even hundreds of thousands of wasted syscalls.
The attributes cache already has a mechanism to help in that scenario in
form of the `git_attr_session`. As long as the same attributes session
is still active, we will not try to re-query the gitmodules files at all
but simply retain our currently cached results. To fix our problem, we
can create a session at the top-most level, which is the initialization
of the `git_diff` structure, and use it in order to look up the correct
diff driver. As the `git_diff` structure is used to generate patches for
multiple files at once, this neatly solves our problem by retaining the
session until patches for all files have been generated.
The fix has been tested with linux.git by calling
`git_diff_tree_to_tree` and `git_diff_to_buf` with v4.10^{tree} and
v4.14^{tree}.
| time | .gitattributes stats
without fix | 33.201s | 844614
with fix | 30.327s | 4441
While execution only improved by roughly 10%, the stat(3) syscalls for
.gitattributes files decreased by 99.5%. The benchmarks were quite
simple with best-of-three timings on Linux ext4 systems. One can assume
that for network based file systems the performance gain will be a lot
larger due to a much higher latency.

streams: openssl: fix thread-safety for OpenSSL error messages
The function `ERR_error_string` can be invoked without providing a
buffer, in which case OpenSSL will simply return a string printed into a
static buffer. Obviously and as documented in ERR_error_string(3), this
is not thread-safe at all. As libgit2 is a library, though, it is easily
possible that other threads may be using OpenSSL at the same time, which
might lead to clobbered error strings.
Fix the issue by instead using a stack-allocated buffer. According to
the documentation, the caller has to provide a buffer of at least 256
bytes of size. While we do so, make sure that the buffer will never get
overflown by switching to `ERR_error_string_n` to specify the buffer's
size.

tests: online::clone: inline creds-test with nonexistent URL
Right now, we test our credential callback code twice, once via SSH on
localhost and once via a non-existent GitHub repository. While the first
URL makes sense to be configurable, it does not make sense to hard-code
the non-existing repository, which requires us to call tests multiple
times. Instead, we can just inline the URL into another set of tests.

tests: online::clone: construct credential-URL from environment
We support two types of passing credentials to the proxy, either via the
URL or explicitly by specifying user and password. We test these types
by modifying the proxy URL and executing the tests twice, which is
in fact unnecessary and requires us to maintain the list of environment
variables and test executions across multiple CI infrastructures.
To fix the situation, we can just always pass the host, port, user and
password to the tests. The tests can then assemble the complete URL
either with or without included credentials, allowing us to test both
cases in-process.

tests: perf: build but exclude performance tests by default
Our performance tests (or to be more concrete, our single performance
test) are not built by default, as they are always #ifdef'd out. While
it is true that we don't want to run performance tests by default, not
compiling them at all may cause code rot and is thus an unfavorable
approach to handle this.
We can easily improve this situation: this commit removes the #ifdef,
causing the code to always be compiled. Furthermore, we add `-xperf` to
the default command line parameters of `generate.py`, thus causing the
tests to be excluded by default.
Due to this approach, we are now able to execute the performance tests
by passing `-sperf` to `libgit2_clar`. Unfortunately, we cannot execute
the performance tests on Travis or AppVeyor as they rely on history
being available for the libgit2 repository. As both do a shallow clone
only, though, this is not given.

The test `iterator::workdir::filesystem_gunk` is usually not executed,

due to its effects on speed. As such, it has become stale and does not
account for new references which have meanwhile been added to the
testrepo, causing it to fail. Fix this by raising the number of expected
references to 15.

When the function `expect_iterator_items` surpasses the number of

current count is still smaller or equal to the expected count inside of
the loop.

Some function bodies of tests which are not applicable to the Win32

This leaves us with no indication that these tests are not being

skipped tests. Improve the situation by calling `cl_skip()` instead of
just doing nothing.

branches: Check symlinked subdirectories
Native Git allows symlinked directories under .git/refs. This
change allows libgit2 to also look for references that live under
symlinked directories.

winhttp: properly support ntlm and negotiate
When parsing unauthorized responses, properly parse headers looking for
both NTLM and Negotiate challenges. Set the HTTP credentials to default
credentials (using a `NULL` username and password) with the schemes
supported by ourselves and the server.

remote: append to FETCH_HEAD rather than overwrite for each refspec
We treat each refspec on its own, but the code currently overwrites the contents
of FETCH_HEAD so we end up with the entries for the last refspec we processed.
Instead, truncate it before performing the updates and append to it when
updating the references.

Fix unpack double free
If an element has been cached, but then the call to
packfile_unpack_compressed() fails, the very next thing that happens is
that its data is freed and then the element is not removed from the
cache, which frees the data again.
This change sets obj->data to NULL to avoid the double-free. It also
stops trying to resolve deltas after two continuous failed rounds of
resolution, and adds a test for this.

tests: add GITTEST_SLOW env var check
Writing very large files may be slow, particularly on inefficient
filesystems and when running instrumented code to detect invalid memory
accesses (eg within valgrind or similar tools).
Introduce `GITTEST_SLOW` so that tests that are slow can be skipped by
the CI system.

hash: commoncrypto hash should support large files
Teach the CommonCrypto hash mechanisms to support large files. The hash
primitives take a `CC_LONG` (aka `uint32_t`) at a time. So loop to give
the hash function at most an unsigned 32 bit's worth of bytes until we
have hashed the entire file.

odb_loose: reject objects that cannot fit in memory
Check the size of objects being read from the loose odb backend and
reject those that would not fit in memory with an error message that
reflects the actual problem, instead of error'ing later with an
unintuitive error message regarding truncation or invalid hashes.

zstream: use UINT_MAX sized chunks
Instead of paging to zlib in INT_MAX sized chunks, we can give it
as many as UINT_MAX bytes at a time. zlib doesn't care how big
a buffer we give it, this simply results in fewer calls into zlib.

odb: support large loose objects
zlib will only inflate/deflate an `int`s worth of data at a time.
We need to loop through large files in order to ensure that we inflate
the entire file, not just an `int`s worth of data. Thankfully, we
already have this loop in our `git_zstream` layer. Handle large objects
using the `git_zstream`.

object: introduce git_object_stringn2type
Introduce an internal API to get the object type based on a
length-specified (not null terminated) string representation. This can
be used to compare the (space terminated) object type name in a loose
object.
Reimplement `git_object_string2type` based on this API.

odb: test loose reading/writing large objects
Introduce a test for very large objects in the ODB. Write a large
object (5 GB) and ensure that the write succeeds and provides us the
expected object ID. Introduce a test that writes that file and
ensures that we can subsequently read it.

util: introduce `git__prefixncmp` and consolidate implementations
Introduce `git_prefixncmp` that will search up to the first `n`
characters of a string to see if it is prefixed by another string.
This is useful for examining if a non-null terminated character
array is prefixed by a particular substring.
Consolidate the various implementations of `git__prefixcmp` around a
single core implementation and add some test cases to validate its
behavior.

zstream: treat `Z_BUF_ERROR` as non-fatal
zlib will return `Z_BUF_ERROR` whenever there is more input to inflate
or deflate than there is output to store the result. This is normal for
us as we iterate through the input, particularly with very large input
buffers.
