ce49d99c2f check.h: remove obsolete header 
Since we switched from autotools to Meson in commit
94592c1406, we don't need to include
`config.h` early to properly enable large file support.  Meson passes
the required macros on the compiler command line instead of defining
them in `config.h`.

This means we can include `config.h` at any time, whenever we want to
check its macros, and there are no ordering constraints.

fee75dc766 {output,mixer}/alsa: use snd_pcm_poll_descriptors_revents() 
This call was missing, causing very high CPU usage when the ALSA
output plugin was used with dmix.

Closes #391

d0fbf6db59 input/Stream: remove attribute "cond", replace with handler interface 
This adds a bit of overhead, but also adds flexibility to the API,
because arbitrary triggers may be invoked from that virtual method
implementation, not just Cond::signal().

The motivation for this is to make the handlers more dynamic, for the
upcoming buffering class utilizing ProxyInputStream.

7e8b448985 input/alsa: set period_size=buffer_size/4 
This way, we have four periods instead of the default of two.  With
only two periods, we don't get woken up often enough, and we
frequently encounter buffer overruns.  With four periods, we have more
time to breathe, and the buffer overruns magically disappear.

92684112ed input/alsa: call snd_pcm_start() after snd_pcm_prepare() 
This is necessary because we'll never get woken up again by
epoll_wait() after a buffer overrun recovery, unless we start the PCM
explicitly before returning to the I/O loop.
