This adds support to diff and status for running filters (a la crlf) on blobs in the workdir before computing SHAs and before generating text diffs. This ended up being a bit more code change than I had thought since I had to reorganize some of the diff logic to minimize peak memory use when filtering blobs in a diff. This also adds a cap on the maximum size of data that will be loaded to diff. I set it at 512Mb which should match core git. Right now it is a #define in src/diff.h but it could be moved into the public API if desired.

This refactors the diff output code so that an iterator object can be used to traverse and generate the diffs, instead of just the `foreach()` style with callbacks. The code has been rearranged so that the two styles can still share most functions. This also replaces `GIT_REVWALKOVER` with `GIT_ITEROVER` and uses that as a common error code for marking the end of iteration when using a iterator style of object.

This replaces the old submodule API with a new extended API that supports most of the things that can be done with `git submodule`.

In looking at PR #878, I found a few small bugs in the diff code, mostly related to work that can be avoided when processing tree- to-tree diffs that was always being carried out. This commit has some small fixes in it.

A diff that is created with a NULL options parameter could result in a NULL prefix string, but diff merge was unconditionally strdup'ing it. I added a test to replicate the issue and then a new method that does the right thing with NULL values.

When the creation of one iterator fails, we need to free the prefix and possibly one of the iterators. Make sure we do so.

This fixes git_index_add and git_index_append to behave more like core git, preserving old filemode data in the index when adding and/or appending with core.filemode = false. This also has placeholder support for core.symlinks and core.ignorecase, but those flags are not implemented (well, symlinks has partial support for preserving mode information in the same way that git does, but it isn't tested).

There are three actual changes in this commit: 1. When the trailing newline of a file is removed in a diff, the change will now be reported with `GIT_DIFF_LINE_DEL_EOFNL` passed to the callback. Previously, the `ADD_EOFNL` constant was given which was just an error in my understanding of when the various circumstances arose. `GIT_DIFF_LINE_ADD_EOFNL` is deprecated and should never be generated. A new newline is simply an `ADD`. 2. Rewrote the `diff_delta__merge_like_cgit` function that contains the core logic of the `git_diff_merge` implementation. The new version doesn't actually have significantly different behavior, but the logic should be much more obvious, I think. 3. Fixed a bug in `git_diff_merge` where it freed a string pool while some of the string data was still in use. This led to `git_diff_print_patch` accessing memory that had been freed. The rest of this commit contains improved documentation in `diff.h` to make the behavior and the equivalencies with core git clearer, and a bunch of new tests to cover the various cases, oh and a minor simplification of `examples/diff.c`.

File modes were both not being ignored properly on platforms where they should be ignored, nor be diffed consistently on platforms where they are supported. This change adds a number of diff and status filemode change tests. This also makes sure that filemode-only changes are included in the diff output when they occur and that filemode changes are ignored successfully when core.filemode is false. There is no code that automatically toggles core.filemode based on the capabilities of the current platform, so the user still needs to be careful in their .git/config file.

This fixes two bugs: * Issue #728 where git_status_file was not working for files that contain spaces. This was caused by reusing the "fnmatch" parsing code from ignore and attribute files to interpret the "pathspec" that constrained the files to apply the status to. In that code, unescaped whitespace was considered terminal to the pattern, so a file with internal whitespace was excluded from the matched files. The fix was to add a mode to that code that allows spaces and tabs inside patterns. This mode only comes into play when parsing in-memory strings. * The other issue was undetected, but it was in the recently added code to reload gitattributes / gitignores when they were changed on disk. That code was not clearing out the old values from the cached file content before reparsing which meant that newly added patterns would be read in, but deleted patterns would not be removed. The fix was to clear the vector of patterns in a cached file before reparsing the file.

There was a bug where tracked files inside directories that were inside ignored directories where not being found by status. To make that a little clearer, if you have a .gitignore with: ignore/ And then have the following files: ignore/dir/tracked <-- actually a tracked file ignore/dir/untracked <-- should be ignored Then we would show the tracked file as being removed (because when we got the to contained item "dir/" inside the ignored directory, we decided it was safe to skip -- bzzt, wrong!). This update is much more careful about checking that we are not skipping over any prefix of a tracked item, regardless of whether it is ignored or not. As documented in diff.c, this commit does create behavior that still differs from core git with regards to the handling of untracked files contained inside ignored directories. With libgit2, those files will just not show up in status or diff. With core git, those files don't show up in status or diff either *unless* they are explicitly ignored by a .gitignore pattern in which case they show up as ignored files. Needless to say, this is a local behavior difference only, so it should not be important and (to me) the libgit2 behavior seems more consistent.

The goal of this work is to rewrite git_status_file to use the same underlying code as git_status_foreach. This is done in 3 phases: 1. Extend iterators to allow ranged iteration with start and end prefixes for the range of file names to be covered. 2. Improve diff so that when there is a pathspec and there is a common non-wildcard prefix of the pathspec, it will use ranged iterators to minimize excess iteration. 3. Rewrite git_status_file to call git_status_foreach_ext with a pathspec that covers just the one file being checked. Since ranged iterators underlie the status & diff implementation, this is actually fairly efficient. The workdir iterator does end up loading the contents of all the directories down to the single file, which should ideally be avoided, but it is pretty good.

When a repo is first created, there is no HEAD yet and attempting to diff files in the index was showing nothing because a tree iterator could not be constructed. This adds an "empty" iterator and falls back on that when the head cannot be looked up.

This converts the git attr related code (including ignores) and the git diff related code (and implicitly the status code) to use `git_pools` for storing strings. This reduces the number of small blocks allocated dramatically.

This adds preliminary support for pathspecs to diff and status. The implementation is not very optimized (it still looks at every single file and evaluated the the pathspec match against them), but it works.

Add a new command `git_repository_open_ext` with extended options that control how searching for a repository will be done. The existing `git_repository_open` and `git_repository_discover` are reimplemented on top of it. We may want to change the default behavior of `git_repository_open` but this commit does not do that. Improve support for "gitdir" files where the work dir is separate from the repo and support for the "separate-git-dir" config. Also, add support for opening repos created with `git-new-workdir` script (although I have only confirmed that they can be opened, not that all functions work correctly). There are also a few minor changes that came up: - Fix `git_path_prettify` to allow in-place prettifying. - Fix `git_path_root` to support backslashes on Win32. This fix should help many repo open/discover scenarios - it is the one function called when opening before prettifying the path. - Tweak `git_config_get_string` to set the "out" pointer to NULL if the config value is not found. Allows some other cleanup. - Fix a couple places that should have been calling `git_repository_config__weakptr` and were not. - Fix `cl_git_sandbox_init` clar helper to support bare repos.

This adds support for a bunch of core.* settings that affect diff and status, plus fixes up some incorrect implementations of those settings from before. Also, this cleans up the handling of config settings in the new submodules code and in the old attrs/ignore code.

I decided that the COITERATE macro was, in the end causing more confusion that it would save and decided just to write out the loops that I needed for parallel diff list iteration. It is not that much code and this just feels less obfuscated.

This fixes the bug that @nulltoken found (thank you!) where if there were untracked directories alphabetically after the last tracked item, the diff implementation would deref a NULL pointer. The fix involved the code which decides if it is necessary to recurse into a directory in the working dir, so it was easy to add a new option `GIT_STATUS_OPT_RECURSE_UNTRACKED_DIRS` to control if the contents of untracked directories should be included in status.

This reverts the changes to the GIT_STATUS constants and adds a new enumeration to describe the type of change in a git_diff_delta. I don't love this solution, but it should prevent strange errors from occurring for now. Eventually, I would like to unify the various status constants, but it needs a larger plan and I just wanted to eliminate this breakage quickly.

It turns out that commit 31e9cfc4cbcaf1b38cdd3dbe3282a8f57e5366a5 did not fix the GIT_USUSED behavior on all platforms. This commit walks through and really cleans things up more thoroughly, getting rid of the unnecessary stuff. To remove the use of some GIT_UNUSED, I ended up adding a couple of new iterators for hashtables that allow you to iterator just over keys or just over values. In making this change, I found a bug in the clar tests (where we were doing *count++ but meant to do (*count)++ to increment the value). I fixed that but then found the test failing because it was not really using an empty repo. So, I took some of the code that I wrote for iterator testing and moved it to clar_helpers.c, then made use of that to make it easier to open fixtures on a per test basis even within a single test file.

This is a major reorganization of the diff code. This changes the diff functions to use the iterators for traversing the content. This allowed a lot of code to be simplified. Also, this moved the functions relating to outputting a diff into a new file (diff_output.c). This includes a number of other changes - adding utility functions, extending iterators, etc. plus more tests for the diff code. This also takes the example diff.c program much further in terms of emulating git-diff command line options.

This is an initial version of git_diff_workdir_to_index. It also includes renaming some structures and some refactoring of the existing code so that it could be shared better with the new function. This is not complete since it needs a rebase to get some new odb functions from the upstream branch.

Once I added tests for the whitespace handling options of diff, I realized that there were some bugs. This fixes those and adds the new tests into the test suite.
