Add index pathspec-based operations
This adds three new public APIs for manipulating the index:
1. `git_index_add_all` is similar to `git add -A` and will add
files in the working directory that match a pathspec to the
index while honoring ignores, etc.
2. `git_index_remove_all` removes files from the index that match
a pathspec.
3. `git_index_update_all` updates entries in the index based on
the current contents of the working directory, either added
the new information or removing the entry from the index.
