Initial implementation of gitignore support

Adds support for .gitignore files to git_status_foreach() and
git_status_file().  This includes refactoring the gitattributes
code to share logic where possible.  The GIT_STATUS_IGNORED flag
will now be passed in for files that are ignored (provided they
are not already in the index or the head of repo).
