Merge branch 'ab/fsck-api-cleanup'

Fsck API clean-up.

* ab/fsck-api-cleanup:
  fetch-pack: use new fsck API to printing dangling submodules
  fetch-pack: use file-scope static struct for fsck_options
  fetch-pack: don't needlessly copy fsck_options
  fsck.c: move gitmodules_{found,done} into fsck_options
  fsck.c: add an fsck_set_msg_type() API that takes enums
  fsck.c: pass along the fsck_msg_id in the fsck_error callback
  fsck.[ch]: move FOREACH_FSCK_MSG_ID & fsck_msg_id from *.c to *.h
  fsck.c: give "FOREACH_MSG_ID" a more specific name
  fsck.c: undefine temporary STR macro after use
  fsck.c: call parse_msg_type() early in fsck_set_msg_type()
  fsck.h: re-order and re-assign "enum fsck_msg_type"
  fsck.h: move FSCK_{FATAL,INFO,ERROR,WARN,IGNORE} into an enum
  fsck.c: refactor fsck_msg_type() to limit scope of "int msg_type"
  fsck.c: rename remaining fsck_msg_id "id" to "msg_id"
  fsck.c: remove (mostly) redundant append_msg_id() function
  fsck.c: rename variables in fsck_set_msg_type() for less confusion
  fsck.h: use "enum object_type" instead of "int"
  fsck.h: use designed initializers for FSCK_OPTIONS_{DEFAULT,STRICT}
  fsck.c: refactor and rename common config callback
