Subject: [PATCH 07/11] pulse: move a couple of PCM related functions from pulse.c to pcm_pulse.c
A number of functions in pulse.c are only relevant for the PCM handling,
so let's move them to pcm_pulse.c. This allows us to simplify their
argument lists a bit.

Subject: [PATCH 08/11] pulse: get rid of redundant state variable
snd_pulse_t::state was mostly shadowing the state of
pa_context_get_state(snd_pulse_t::context), so get rid of it and use the
state of the context directly.

Subject: [PATCH 09/11] pulse: unify stream/context state checks
Unify (and simplify) the paths that check for the validity of a
stream/context: always call into check_stream()/pulse_check_connection()
when applicable instead of rolling our own checks each time. Also check
for validity of mainloop before locking it.

Make sure we deal better with partially initialized structs.
Don't check for pointer state before calling free() since free() does
that anyway.

This makes "aplay" handle connections shutdown similar to hardware
