3830748de5 output/alsa: clear the period_buffer in LockCaughtError() 
The method Cancel() assumes that the `period_buffer` must be empty
when `active==false`, but that is not the case when Play() fails.

Of course the assertion in Cancel() is not 100% correct, but I decided
to rather fix this in LockCaughtError() because the `period_buffer`
should only be accessed from within the RTIO thread, and this is the
only code path where `active` can be set to `false` with a non-empty
`period_buffer`.

Fixes #423

1a43f5145d output/alsa: throw on snd_pcm_writei() error while draining 
This implements real error handling, and avoids calling
CancelInternal() from this code path.

6c2a6a65e0 output/alsa: remove snd_pcm_state() check from DrainInternal() 
This check was added 9 years ago in commit
4dc25d3908 to work around a dmix bug
which I assume has been fixed long ago.

Removing this fixes another corner case: if draining is requested
before the start threshold is reached, the PCM is still in
SND_PCM_STATE_PREPARED but not yet SND_PCM_STATE_RUNNING, which means
the submitted data will never be played.  This corner case is
realistic when playing songs shorter than the ALSA buffer (if the
buffer is very large).

4247a757b3 output/alsa: call snd_pcm_prepare() if draining is requested early 
This fixes a corner case which has probably never occurred and
probably never will: if Cancel() is called, and then Play() followed
by Drain(), the plugin should really play that data.  However
currently, this never happens, because snd_pcm_prepare() is never
called.

98d76627a5 output/alsa: disable events in Cancel() 
Don't reactivate the PCM device immediately after Cancel() is
finished; if Cancel() gets called this may mean that new data may take
a while to produce, or no data at all will be produced because the
current song is being stopped.

Once new data is available, Play() will automatically reactivate the
PCM.

This fixes underruns when switching songs manually (closes #264).

febd1ad09c output/alsa: fix deadlock bug 
After UnlockActivate() returns, we not only need to check for errors,
but also for more room in the ring buffer.  If we don't check the ring
buffer, it may be drained already, and the cond.wait() call will never
finish.

a199366157 output/alsa: remove period_time adjust loop 
This loop was introduced in commit
24c1f46353, but -EPIPE is not a possible
error condition for snd_pcm_hw_params().  This code does not appear to
make sense.  Problems with a wrong period_time should be caught before
that by snd_pcm_hw_params_set_period_time_near().

This commit removes the last "goto" in MPD!  Yay!
