d29d186d62 output/alsa: use a new I/O thread with real-time scheduling 
The normal I/O event thread can have a large latency, e.g. when
libgnutls loads all TLS CA certificates for a https connect.  This
makes it unreliable for the ALSA I/O notifications, and causes ring
buffer xruns.  To avoid interfering with high latency events such as
CURL's, we move the ALSA I/O events to a separate I/O thread which
also obtains real-time scheduling (if possible).

Closes #221

dfaf08743c *: check defined(_WIN32) instead of defined(WIN32) 
Only _WIN32 is defined by the compiler, and WIN32 is not standardized
and may be missing.

0ff4350352 event/ServerSocket: pass UniqueSocketDescriptor by value 
Passing it by value is actually smaller (32 bit) than the rvalue
reference (64 bit pointer), and it ensures that the object is consumed
after the call returns, no matter how the methods are implemented.
