Move the FSCK_{FATAL,INFO,ERROR,WARN,IGNORE} defines into a new
fsck_msg_type enum.
These defines were originally introduced in:
- ba002f3b28 (builtin-fsck: move common object checking code to
fsck.c, 2008-02-25)
- f50c440730 (fsck: disallow demoting grave fsck errors to warnings,
2015-06-22)
- efaba7cc77 (fsck: optionally ignore specific fsck issues
completely, 2015-06-22)
- f27d05b170 (fsck: allow upgrading fsck warnings to errors,
2015-06-22)
The reason these were defined in two different places is because we
use FSCK_{IGNORE,INFO,FATAL} only in fsck.c, but FSCK_{ERROR,WARN} are
used by external callbacks.
Untangling that would take some more work, since we expose the new
"enum fsck_msg_type" to both. Similar to "enum object_type" it's not
worth structuring the API in such a way that only those who need
FSCK_{ERROR,WARN} pass around a different type.
