libify git-ls-files directory traversal
This moves the core directory traversal and filename exclusion logic into the general git library, making it available for other users directly. If we ever want to do "git commit" or "git add" as a built-in (and we do), we want to be able to handle most of git-ls-files as a library. NOTE! Not all of git-ls-files is libified by this. The index matching and pathspec prefix calculation is still in ls-files.c, but this is a big part of it.
