When we know the file size (because we're producing it from a working directory iterator, or an index with an up-to-date cache) then set a flag indicating as such. This removes the ambiguity about a 0 file size, which could indicate that a file exists and is 0 bytes, or that we haven't read it yet.

Introduce `git_fs_path`, which operates on generic filesystem paths. `git_path` will be kept for only git-specific path functionality (for example, checking for `.git` in a path).

Looking up a non-existent object currently always invokes `git_odb_refresh`. If looking up a large batch of objects, many of which may legitimately not exist, this will repeatedly refresh the ODB to no avail. Add a `git_odb_exists_ext` that accepts flags controlling the ODB lookup, and add a flag to suppress the refresh. This allows the user to control if and when they refresh (for instance, refreshing once before starting the batch).

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.

Separate the concerns of the hash functions from the git_oid functions. The git_oid structure will need to understand either SHA1 or SHA256; the hash functions should only deal with the appropriate one of these.

This change introduces git_odb_write_multi_pack_index(), which creates a `multi-pack-index` file from all the `.pack` files that have been loaded in the ODB. Fixes: #5399

Introduce GIT_OPT_SET_ODB_LOOSE_PRIORITY and GIT_OPT_SET_ODB_PACKED_PRIORITY to allow overriding the default priority values for the default ODB backends. Libgit2 has historically assumed that most objects for long- running operations will be packed, therefore GIT_LOOSE_PRIORITY is set to 1 by default, and GIT_PACKED_PRIORITY to 2. When a client allows libgit2 to set the default backends, they can specify an override for the two priority values in order to change the order in which each ODB backend is accessed.

Introduce `git_filter_list__convert_buf` which behaves like the old implementation of `git_filter_list__apply_data`, where it might move the input data buffer over into the output data buffer space for efficiency. This new implementation will do so in a more predictible way, always freeing the given input buffer (either moving it to the output buffer or filtering it into the output buffer first). Convert internal users to it.

This change does a medium-size refactor of the git_commit_graph_file and the interaction with the ODB. Now instead of the ODB owning a direct reference to the git_commit_graph_file, there will be an intermediate git_commit_graph. The main advantage of that is that now end users can explicitly set a git_commit_graph that is eagerly checked for errors, while still being able to lazily use the commit-graph in a regular ODB, if the file is present.

This change makes revwalks a bit faster by using the `commit-graph` file (if present). This is thanks to the `commit-graph` allow much faster parsing of the commit information by requiring near-zero I/O (aside from reading a few dozen bytes off of a `mmap(2)`-ed file) for each commit, instead of having to read the ODB, inflate the commit, and parse it. This is done by modifying `git_commit_list_parse()` and letting it use the ODB-owned commit-graph file. Part of: #5757

This change: * Starts using GCC's and clang's `__atomic_*` intrinsics instead of the `__sync_*` ones, since the former supercede the latter (and can be safely replaced by their equivalent `__atomic_*` version with the sequentially consistent model). * Makes `git_atomic64`'s value `volatile`. Otherwise, this will make ThreadSanitizer complain. * Adds ways to load the values from atomics. As it turns out, unsynchronized read are okay only in some architectures, but if we want to be correct (and make ThreadSanitizer happy), those loads should also be performed with the atomic builtins. * Fixes two ThreadSanitizer warnings, as a proof-of-concept that this works: - Avoid directly accessing `git_refcount`'s `owner` directly, and instead makes all callers go through the `GIT_REFCOUNT_*()` macros, which also use the atomic utilities. - Makes `pool_system_page_size()` race-free.

When compiling libgit2 with -DDEPRECATE_HARD, we add a preprocessor definition `GIT_DEPRECATE_HARD` which causes the "git2/deprecated.h" header to be empty. As a result, no function declarations are made available to callers, but the implementations are still available to link against. This has the problem that function declarations also aren't visible to the implementations, meaning that the symbol's visibility will not be set up correctly. As a result, the resulting library may not expose those deprecated symbols at all on some platforms and thus cause linking errors. Fix the issue by conditionally compiling deprecated functions, only. While it becomes impossible to link against such a library in case one uses deprecated functions, distributors of libgit2 aren't expected to pass -DDEPRECATE_HARD anyway. Instead, users of libgit2 should manually define GIT_DEPRECATE_HARD to hide deprecated functions. Using "real" hard deprecation still makes sense in the context of CI to test we don't use deprecated symbols ourselves and in case a dependant uses libgit2 in a vendored way and knows it won't ever use any of the deprecated symbols anyway.

Our file utils functions all have a "futils" prefix, e.g. `git_futils_touch`. One would thus naturally guess that their definitions and implementation would live in files "futils.h" and "futils.c", respectively, but in fact they live in "fileops.h". Rename the files to match expectations.

Custom backends can allocate memory when reading objects and providing them to libgit2. However, if an error occurs in the custom backend after the memory has been allocated for the custom object but before it's returned to libgit2, the custom backend has no way to free that memory and it must be leaked. Provide a free function that corresponds to the alloc function so that custom backends have an opportunity to free memory before they return an error.
Edward Thomson committed -
The `git_odb_backend_malloc` name is a system function that is provided for custom ODB backends and allows them to allocate memory for an ODB object in the read callback. This is important so that libgit2 can later free the memory used by an ODB object that was read from the custom backend. However, the name _suggests_ that it actually allocates a `git_odb_backend`. It does not; rename it to make it clear that it actually allocates backend _data_.

Functions that free a structure's contents but not the structure itself shall be named `dispose` in the libgit2 project, but the function `git_cache_free` does not follow this naming pattern. Fix this by renaming it to `git_cache_dispose` and adjusting all callers to make use of the new name.

We use the term "invalid" to refer to bad or malformed data, eg `GIT_REF_INVALID` and `GIT_EINVALIDSPEC`. Since we're changing the names of the `git_object_t`s in this release, update it to be `GIT_OBJECT_INVALID` instead of `BAD`.

This change fixes a bunch of warnings that were discovered by compiling with `clang -target=i386-pc-linux-gnu`. It turned out that the intrinsics were not necessarily being used in all platforms! Especially in GCC, since it does not support __has_builtin. Some more warnings were gleaned from the Windows build, but I stopped when I saw that some third-party dependencies (e.g. zlib) have warnings of their own, so we might never be able to enable -Werror there.

The `git_odb_stream` members `declared_size` and `received_bytes` are both of the type `git_off_t`, which we usually defined to be a 64 bit signed integer. Thus, passing these members to "PRIdZ" formatters is not correct, as they are not guaranteed to accept big enough numbers. Instead, use the "PRId64" formatter, which is able to represent 64 bit signed integers.
