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.

c2b67043	2012-04-25T15:20:28	Rename git_khash_str to git_strmap, etc. This renamed `git_khash_str` to `git_strmap`, `git_hash_oid` to `git_oidmap`, and deletes `git_hashtable` from the tree, plus adds unit tests for `git_strmap`.
19fa2bc1	2012-04-17T15:12:50	Convert attrs and diffs to use string pools 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.
2bc8fa02	2012-04-17T10:14:24	Implement git_pool paged memory allocator This adds a `git_pool` object that can do simple paged memory allocation with free for the entire pool at once. Using this, you can replace many small allocations with large blocks that can then cheaply be doled out in small pieces. This is best used when you plan to free the small blocks all at once - for example, if they represent the parsed state from a file or data stream that are either all kept or all discarded. There are two real patterns of usage for `git_pools`: either for "string" allocation, where the item size is a single byte and you end up just packing the allocations in together, or for "fixed size" allocation where you are allocating a large object (e.g. a `git_oid`) and you generally just allocation single objects that can be tightly packed. Of course, you can use it for other things, but those two cases are the easiest.

This commit introduces a could new git error classes, including the catchall class: GITERR_INVALID which I'm using as the class for invalid and out of range values which are detected at too low a level of library to use a higher level classification. For example, an overflow error in parsing an integer or a bad letter in parsing an OID string would generate an error in this class.

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.

Kill the old `git_fbuffer` and read files straight into `git_buf` objects. Also: In order to fully support 4GB files in 32-bit systems, the `git_buf` implementation has been changed from using `ssize_t` for storage and storing negative values on allocation failure, to using `size_t` and changing the buffer pointer to a magical pointer on allocation failure. Hopefully this won't break anything.

Simplify GIT_UNUSED macros Since casting to void works to eliminate errors with unused parameters on all platforms, avoid the various special cases. Over time, it will make sense to eliminate the GIT_UNUSED macro completely and just have GIT_UNUSED_ARG.
