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....

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)....

Add a new SignalHandled decorator

This decorator can be used to call a function holding with protection
from a given signal. The function should accept a dict of
utils.SignalHandler, indexed by signal number, and make use of it.

SignalHandler, only accept list of signals

utils.SignalHandler can accept either a list of signals or a single
signal, but it's always called with a list. Removing the single signal
option.

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
anyway.
