Re: [PATCH 1/8] git-apply: work from subdirectory.

This adds three things:

 - prefix_filename() is like prefix_path() but can be used to
   name any file on the filesystem, not the files that might go
   into the index file.

 - git-apply uses setup_git_directory() to find out the GIT_DIR
   and reads configuration file.  Later this would allow us to
   affect the behaviour of the command from the configuration.

 - When git-apply is run from a subdirectory, it applies the
   given patch only to the files under the current directory and
   below.

This breaks git-apply when used to just do a "diffstat", or when used on a 
non-git repository.

For "git-apply --stat", we definitely don't want to force it inside a git 
directory. In fact, even _trying_ to find a git directory would be wrong.

The only case where we care about a git directory is the "--index" case. 
In all other cases we should happily apply it (or stat it).
