[PATCH v3 00/31] nd/parse-pathspec

Changes from v2 (it's hard to keep track of after the rebase, so I may be missing something here):

 - rebased on top of recent master, incorporate changes in
   init_pathspec from jk/pathspec-literal and nd/pathspec-wildcard to
   parse_pathspec

 - kill strip_trailing_slash_from_submodules and treat_gitlinks
   (pretty sure it'll cause conflicts with as/check-ignore)

 - kill init_pathspec, match_pathspec, diff_tree_setup_paths and
   diff_tree_release_paths
 
 - check points for future pathspec development

As far as I understand the "pathspec unification", I'd say we are there, with a few exceptions like "mv", external commands.. But those are pretty much isolated.

I'll send another WIP series implementing :(icase) and :(glob), mainly to show (me) how future pathspec feature development looks like after this.
