1. the known users of async don't upgrade
2. async becomes a win when concurrent connections exceed a few hundred simultaneous
3. anyone that needs async should be looking at Haraka instead
4. the perl async dependencies aren't maintained
on files in plugins dir:
fixed a number of POD errors
formatted some # comments into POD
removed bare 1; (these are plugins, not perl modules)
most instances of this were copy/pasted from a previous plugin that had it
removed instances of # vim ts=N ...
they weren't consistent, many didn't match .perltidyrc
on modules that failed perl -c tests, added 'use Qpsmtpd::Constants;'

Jost Krieger pointed out that the documentation for the header check called
for a config_headers, but the code actually implemented scan_headers. Updated
to accept either. Also the condition for actually checking/skipping the
headers was inverted.
Also whitespace fixes.
