thanks to milki for all the efforts!
Details:
- partial-copy fell afoul of BSD not having $RANDOM
- test suite: fix bad GNU sort with good perl sort
- test suite: fix md5sum dependency (which BSD doesn't have or can't
easily have or requires extra options or whatever...), by doing it
in perl. (Requires Digest::MD5, which is probably available
anyway, but since this is only for the test suite, meh!)
- a remote "id" (usually the IP) is generated and logged on the first
log message in a "transaction"
- speaking of which, a new "transaction ID" is logged that stays the
same for each input command/invocation, tying together all the
spawned commands
- so now time stamps can be generated each time they are needed,
rather than re-use the one at the beginning
- log messages have a keyword at the start now
remote, (create), check1 -- from gitolite-shell
update, check2 -- from update
post-up -- from post-update
command -- from gitolite
die, system -- from anywhere
