add initial support for commit notifications to gotd(8)
At present only email notifications are implemented.
Code for HTTP notifications is not yet finished, hence HTTP-related
documentation remains hidden for now.
This adds a new 'notify' process which has an "exec" pledge. It runs
helper programs which implement the notification transport layer,
such as got-notify-email which speaks SMTP. This design avoids having
to link all of gotd with network libraries and related crypto libraries.
Notification content is generated by the 'repo_write' process. Commit log
messages and diffstats are written to a file which the 'notify' process
will pass on to its helpers on stdin. The default output looks similar
to 'got log -d'. If too many new commits are present the output looks
similar to 'got log -s' instead. Tags always look like 'got tag -l'.
The session process coordinates generation of notifications. It maintains
a notification queue which holds one notification per updated reference,
and passes notification requests from this queue to the 'repo_write'
process for notification content creation and then to the 'notify'
process for notification delivery.
Only one notification can be in flight at a time to avoid file descriptor
starvation if many references get updated in a single client session.
