[PATCH v5 0/5] add --stdin parsing API, use in pack-objects

A trivial re-roll of v4[1] on top of gitster/bc/rev-list-without-commit-line, which it had a conflict with. Also includes the s/int/unsigned int/ fixup that Junio applied on the v4 he picked up.

Ævar Arnfjörð Bjarmason (5):
  upload-pack: run is_repository_shallow() before setup_revisions()
  revision.h: refactor "disable_stdin" and "read_from_stdin"
  revision.[ch]: add a "handle_stdin_line" API
  pack-objects.c: do stdin parsing via revision.c's API
  pack-objects.c: make use of REV_INFO_STDIN_LINE_PROCESS
