This makes git__swap use the __sync_lock_test_and_set primitive with GCC and the InterlockedExchangePointer primitive with MSVC. Previously is used compare_and_swap in a way that was probably unintuitive for most thinking (i.e. it could fail to swap in the value if another thread raced in). Now it will always succeed and the last thread to run in a race will win instead of the first thread. This also fixes up a little confusion between volatile void ** and void * volatile * that came up with the Win32 compiler.

Improve submodules status data caching and compatibility
Vicent Martí committed -
This restores a behavior that was accidentally lost during some diff refactoring where an untracked directory that contains a .git item should be treated as IGNORED, not as UNTRACKED. The submodule code already detects this, but the diff code was not handling the scenario right. This also updates a number of existing tests that were actually exercising the behavior but did not have the right expectations in place. It actually makes the new `test_diff_submodules__diff_ignore_options` test feel much better because the "not-a-submodule" entries are now ignored instead of showing up as untracked items. Fixes #1697

This adds correct support for an equivalent to --ignore-submodules in diff, where an actual ignore value can be passed to diff to override the per submodule settings in the configuration. This required tweaking the constants for ignore values so that zero would not be used and could represent an unset option to the diff. This was an opportunity to move the submodule values into include/git2/types.h and to rename the poorly named DEFAULT values for ignore and update constants to RESET instead. Now the GIT_DIFF_IGNORE_SUBMODULES flag is exactly the same as setting the ignore_submodules option to GIT_SUBMODULE_IGNORE_ALL (which is actually a minor change from the old behavior in that submodules will now be treated as UNMODIFIED deltas instead of being left out totally - if you set GIT_DIFF_INCLUDE_UNMODIFIED). This includes tests for the various new settings.

Submodules now expose an internal status API that allows diff to get back the OID values from the submodule very easily and also to avoiding caching issues and to override the ignore setting for the submodule.

This fixes the way that submodule status is checked to bypass just about all of the caching in the submodule object. Based on the ignore value, it will try to do the minimum work necessary to find the current status of the submodule - but it will actually go to disk to get all of the current values. This also removes the custom refcounting stuff in favor of the common git_refcount style. Right now, it is still for internal purposes only, but it should make it easier to add true submodule refcounting in the future with a public git_submodule_free call that will allow bindings not to worry about the submodule object getting freed from underneath them.

This adds a BARE option to git_repository_open_ext which allows a fast open path that still knows how to read gitlinks and to search for the actual .git directory from a subdirectory. `git_repository_open_bare` is still simpler and faster, but having a gitlink aware fast open is very useful for submodules where we want to quickly be able to peek at the HEAD and index data without doing any other meaningful repo operations.

This is probably not the final form of this change, but this is a preliminary version of checking a timestamp to see if the cached working directory HEAD OID matches the current. Right now, this uses the timestamp on the index and is, like most of our timestamp checking, subject to having only second accuracy.

The submodules code caches data about submodules in a way that can cause problems. This adds some tests that try making various modifications to the state of a submodule to see where we can catch out problems in the submodule caching. Right now, I've put in an extra git_submodule_reload_all so that the test will pass, but with that commented out, the test fails. I'm working on fixing the broken version of the test at which point I'll commit the fix and delete the extra reload that makes the test pass.

This controls for the diff.mnemonicprefix setting so that can't break the tests. Also, this expands one test to emulate an ObjectiveGit test more closely.

This adds an additional pathspec API that will match a pathspec against a diff object. This is convenient if you want to handle renames (so you need the whole diff and can't use the pathspec constraint built into the diff API) but still want to tell if the diff had any files that matched the pathspec. When the pathspec is matched against a diff, instead of keeping a list of filenames that matched, instead the API keeps the list of git_diff_deltas that matched and they can be retrieved via a new API git_pathspec_match_list_diff_entry. There are a couple of other minor API extensions here that were mostly for the sake of convenience and to reduce dependencies on knowing the internal data structure between files inside the library.

This is a simple bit vector object that is not resizable after the initial allocation but can be of arbitrary size. It will keep the bti vector entirely on the stack for vectors 64 bits or less, and will allocate the vector on the heap for larger sizes. The API is uniform regardless of storage location. This is very basic right now and all the APIs are inline functions, but it is useful for storing an array of boolean values.

This converts the array of parent SHAs from a git_vector where each SHA has to be separately allocated to a git_array_t where all the SHAs can be kept in one block. Since the two collections have almost identical APIs, there isn't much involved in making the change. I did add an API to git_array_t so that it could be allocated at a precise initial size.

This fixes the way the example log program decides if a merge commit should be shown when a pathspec is given. Also makes it easier to use the pathspec API to just check "does a tree match anything in the pathspec" without allocating a match list.

This adds more command line processing to the example version of log. In particular, this adds the funky command line processing that allows an arbitrary series of revisions followed by an arbitrary number of paths and/or glob patterns. The actual logging part still isn't implemented.

This adds a new public API for compiling pathspecs and matching them against the working directory, the index, or a tree from the repository. This also reworks the pathspec internals to allow the sharing of code between the existing internal usage of pathspec matching and the new external API. While this is working and the new API is ready for discussion, I think there is still an incorrect behavior in which patterns are always matched against the full path of an entry without taking the subdirectories into account (so "s*" will match "subdir/file" even though it wouldn't with core Git). Further enhancements are coming, but this was a good place to take a functional snapshot.
