Note: I'm not sure if it's worth documenting and supporting this
long-term.

We can can avoid taking locks for invocations of "index --all"
and rely on high-resolution ctime (struct timespec st_ctim)
comparisons of msgmap.sqlite3 and the packed-refs + refs/heads
directory of the newest epoch.

This cuts public-inbox-index invocations with
"--all --no-update-extindex -L basic" down from 0.92s to 0.31s.
The change with "-L medium" or "-L full" and (default) non-zero
jobs is even more drastic, reducing a 12-13s no-op invocation
down to the same 0.31s
