Code clean-up.

* jk/snprintf-cleanups:
  daemon: use an argv_array to exec children
  gc: replace local buffer with git_path
  transport-helper: replace checked snprintf with xsnprintf
  convert unchecked snprintf into xsnprintf
  combine-diff: replace malloc/snprintf with xstrfmt
  replace unchecked snprintf calls with heap buffers
  receive-pack: print --pack-header directly into argv array
  name-rev: replace static buffer with strbuf
  create_branch: use xstrfmt for reflog message
  create_branch: move msg setup closer to point of use
  avoid using mksnpath for refs
  avoid using fixed PATH_MAX buffers for refs
  fetch: use heap buffer to format reflog
  tag: use strbuf to format tag header
  diff: avoid fixed-size buffer for patch-ids
  odb_mkstemp: use git_path_buf
  odb_mkstemp: write filename into strbuf
  do not check odb_mkstemp return value for errors
