remove pathspec_match, use match_pathspec instead

Both versions have the same functionality. This removes any
redundancy.

This also adds makes two extensions to match_pathspec:

- If pathspec is NULL, return 1. This reflects the behavior of git
  commands, for which no paths usually means "match all paths".

- If seen is NULL, do not use it.
