msgtime: drop Date::Parse for RFC2822
Date::Parse is not optimized for RFC2822 dates and isn't
packaged on OpenBSD. It's still useful for historical
email when email clients were less conformant, but is
less relevant for new emails.

git: async batch interface
This is a transitionary interface which does NOT require an
event loop. It can be plugged into in current synchronous code
without major surgery.
It allows HTTP/1.1 pipelining-like functionality by taking
advantage of predictable and well-specified POSIX pipe semantics
by stuffing multiple git cat-file requests into the --batch pipe
With xt/git_async_cmp.t and GIANT_GIT_DIR=git.git, the async
interface is 10-25% faster than the synchronous interface since
it can keep the "git cat-file" process busier.
This is expected to improve performance on systems with slower
storage (but multiple cores).

TODO: update and add a few more items
SpamAssassin has used re2c (via sa-compile) for many years, now,
and it seems to work fine, there. GMime also looks promising
when combined with Inline::C since GMime can operate on mmap-ed

Given the inevitable demise of many .orgs when price rise;
supporting a URL rewriter similar to .mailmap makes sense.

Makefile.PL: MANIFEST dependency fix
We need to force an update to Makefile (not Makefile.PL) when
MANIFEST changes. Since "Makefile" (aka. "$(FIRST_MAKEFILE)")
is already a single-colon make target; we can't create a
double-colon rule to augment it. So we'll continue using a
"Makefile.PL" rule, but have it recreate the resulting Makefile
Finally, change the "check" target to use "prove -b" instead of
"prove -l" so we test against "blib/lib", since what's in the
"blib" dir will be installed.

httpd|nntpd: avoid missed signal wakeups
Our attempt at using a self-pipe in signal handlers was
ineffective, since pure Perl code execution is deferred
and Perl doesn't use an internal self-pipe/eventfd. In
retrospect, I actually prefer the simplicity of Perl in
this regard...
We can use sigprocmask() from Perl, so we can introduce
signalfd(2) and EVFILT_SIGNAL support on Linux and *BSD-based
systems, respectively. These OS primitives allow us to avoid a
race where Perl checks for signals right before epoll_wait() or
kevent() puts the process to sleep.
The (few) systems nowadays without signalfd(2) or IO::KQueue
will now see wakeups every second to avoid missed signals.
