AsyncUDPSocket: abstract do_read function

This basically implements read handling, without catching all
exceptions. When using the socket in synchronous mode, it's useful to
avoid losing exception data (which, in an async daemon, can only be

Add capability to use syslog for logging

This patch adds a configure-time parameter that will set the defaults
used by all programs, and command-line parameters in the daemons that
allow overriding it.

Syslog 'yes' enables syslog in addition to file-based logging, 'only'...

Reinsert simple timers in Mainloop

This time we use the standard python sched module, rather than doing it
all by ourselves. The scheduler in mainloop can be manipulated directly
by callers, to enter new events.

Convert the http server/mainloop to asyncore

We can avoid most of the Mainloop.Run() code if we use asyncore
for delivering I/O events, and just concentrate on what's missing in
asyncore: singnal handling and timers. This way confd can be ported to
use Mainloop as well....

Pass the correct signal to handlers

Mainloop currently calls all handlers with the signal number harcoded to

Convert daemon.Mainloop to @SignalHandled

This makes the function a lot simpler, since it used to install two
different signal handlers, which are now transparently handled by the
decorator. The code is unindented, but remains unchanged apart from the
part that checks the signal handlers (which is now collapsed toghether)....

Simplify IO waiting in Mainloop

IO is never unregistered in our current usage, so dropping that
functionality for now. Also putting the poller outside of the Run()
function allows us to avoid the double step of adding tuples to an
_io_wait_add queue and adding them later in the main loop....

Remove timers from Mainloop

Timers are currently unused, slightly buggy (for example timeout doesn't
get updated correctly), and unneeded in the current form. Confd will
have timeouts in more simple fashion, and is not a mainloop user
