Some fairly major changes to -watch. Filesys::Notify::Simple is
no longer used, and -watch now uses inotify, signalfd or kevent
like the read-only daemons.
Credentials are handled via Net::Netrc (Perl standard library)
or "git-credential", so we do no password storage on our own.
NNTP (and non-IDLE IMAP) may allow more parallelization in the
future.
One significant project-wide change is getting rid of "use
fields". It gets in my way more than it helps, and it's
probably alien to a fair amount of Perl hackers. AFAIK, it's
never really been popular outside of Danga::Socket-based
projects.
Eric W. Biederman (1):
IMAPTracker: Add a helper to track our place in reading imap mailboxes

This allows callers to avoid creating expensive closures.
We no longer pass the `$now' value to callers, as none of
the callers used it.
