[PATCH 0/6] removing more calls to git_path()

After the discussion about the git_path()-related bug in:

  http://public-inbox.org/git/20170329080820.8084-1-chriscool@tuxfamily.org/

I looked over some of the calls. When I introduced git_pathdup() a few years ago I converted most of the dangerous git_path() calls. But there were still some left, and of course new ones have been added. This patch cleans up some of the low-hanging fruit.

There's probably more that could be done, but this is just what I happened to produce when looking through some of the cases the other day. I don't think any of these is fixing a triggerable bug; they can all be considered cleanup.

  [1/6]: bisect: add git_path_bisect_terms helper
  [2/6]: branch: add edit_description() helper
  [3/6]: use git_path_* helper functions
  [4/6]: replace xstrdup(git_path(...)) with git_pathdup(...)
  [5/6]: replace strbuf_addstr(git_path()) with git_path_buf()
  [6/6]: am: drop "dir" parameter from am_state_init
