[PATCH 00/21] nd/struct-pathspec v2

Changes from previous version [1]

 - fixes depth limit and overlapping pathspecs, by checking deepest
   pathspecs first. struct pathspec is now sorted (raw[] untouched)

 - match_pathspec_depth depends on new match_pathspec_item() (a
   clone of match_one(), but takes advantage of struct pathspec)

 - ce_path_match uses struct pathspec

 - strbuf is used instead of fixed length "base" buffer. This
   introduces the weird strbuf_offset() function.

 - never_interesting is disabled if any wildcards is present

 - struct pathspec * == NULL is unacceptable, callers must pass
   non-NULL.

 - a bit more tests
