mwindow: Fix a bug in the LRU window finding code
This change now updates the `lru_window` variable to match the current
file's MRU window. This makes it such that it doesn't always choose the
file that happened to come last in the list of window files, and instead
should now correctly choose the file with the least-recently-used one.

zlib: Add support for building with Chromium's zlib implementation
This change builds libgit2 using Chromium's zlib implementation by
invoking cmake with `-DUSE_BUNDLED_ZLIB=ON -DUSE_CHROMIUM_ZLIB=ON`,
which is ~10% faster than the bundled zlib for the core::zstream suite.
This version of zlib has some optimizations:
a) Decompression (Intel+ARM): inflate_fast, adler32, crc32, etc.
b) Compression (Intel): fill_window, longest_match, hash function, etc.
Due to the introduction of SIMD optimizations, and to get the maximum
performance out of this fork of zlib, this requires an x86_64 processor
with SSE4.2 and CLMUL (anything Westmere or later, ~2010). The Chromium
zlib implementation also supports ARM with NEON, but it has not been
enabled in this patch.
Performance
===========
TL;DR: Running just `./libgit2_clar -score::zstream` 100 times in a loop
took 0:56.30 before and 0:50.67 after (~10% reduction!).
The bundled and system zlib implementations on an Ubuntu Focal system
perform relatively similar (the bundled one is marginally better due to
the compiler being able to inline some functions), so only the bundled
and Chromium zlibs were compared.
For a more balanced comparison (to ensure that nothing regressed
overall), `libgit2_clar` under `perf` was also run, and the zlib-related
functions were compared.

Fix the `-DENABLE_WERROR=ON` build for gcc 10.2
This change makes it possible to build with newer versions of gcc
without warnings. There were two warnings issued:
* gcc 8 added
[`-Wstringop-truncation`](https://developers.redhat.com/blog/2018/05/24/detecting-string-truncation-with-gcc-8/),
which warns if a call to `strncpy(3)` is prone to accidentally
truncating the destination string, since `strncpy(3)` does NOT add a
terminating `NULL` if the destination buffer is not large enough to
hold the input.
This change uses the pattern suggested in
https://us-cert.cisa.gov/bsi/articles/knowledge/coding-practices/strncpy-and-strncat
to fix the locations flagged by gcc.
* There was a potentially uninitialized access of `dest` in `fs_copy`.

repository: use intptr_t's in the config map cache
Since we're using atomic primitives to read and write into the config
map cache, we need to read/write something pointer-sized. Use an
`intptr_t` for the config map cache.

Add tests for `git__multiply_int64_overflow`
As it turns out, the implementation of `git__multiply_int64_overflow` is
full of edge cases and tricky arithmetic. That means that it should have
unit tests.
As a result, a bug in `git__strntol64` was found (and fixed!) in
clang+32-bit.

Avoid using `__builtin_mul_overflow` with the clang+32-bit combo
This causes clang to produce an undefined reference to `__mulodi4`. This
could be fixed by statically linking some compiler-rt libraries to
provide this symbol, but let's first stop the bleeding since doing the
correct long-term fix requires some non-trivial CMake knowledge which I
lack.

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
\# ........ .............. .............
\#
0.25% 0.321836 libgit2_clar

Cache the parsed submodule config when diffing
This change makes that anything that calls `git_diff__from_iterators`
(any of the `git_diff_xxx` functions) only need to parse the
`.gitmodules` file once. This can be avoided by calling
`git_repository_submodule_cache_all(...)`, but we can do that safely for
the user with no change in semantics.

alloc: set up an allocator that fails before library init
We require the library to be initialized with git_libgit2_init before it
is functional. However, if a user tries to uses the library without
doing so - as they might when getting started with the library for the
first time - we will likely crash.
This commit introduces some guard rails - now instead of having _no_
allocator by default, we'll have an allocator that always fails, and
never tries to set an error message (since the thread-local state is
set up by git_libgit2_init). We've modified the error retrieval
function to (try to) ensure that the library has been initialized before
getting the thread-local error message.
(Unfortunately, we cannot determine if the thread local storage has
actually been configured, this does require initialization by
git_libgit2_init. But a naive attempt should be good enough for most
cases.)

libgit2: provide init_count of the library
A function to provide the initialization count of the library; this is

Provide more clarity for Win32 calling conventions - now that we always

for things that need callbacks from NTAPI code (eg fiber-local storage).

Implement generic TLS interface
This adds a generic TLS interface for anyone to store TLS data. It is designed to work regardless of whether threading support is built into the library or not.
Nobody in the library should directly interface with the data on the TLS struct, so it's been built to be opaque even in the library.
Requires the allocator to be initialized before use.
