Add macro HAVE_THREAD_NAME which is set when any method to set the

instead of just checking for HAVE_PTHREAD_SETNAME_NP.

Here's a change to dynamically allocate the DSD ID3 tag buffer.
Pretty much anything with cover art is going to exceed the existing,
static 4k limit...  Here's a change to dynamically allocate the buffer
and sanity check it at some upper limit.  I rather arbitrarily pulled
256k out of thin air just to keep a corrupt file from causing it to
trying to allocate a buffer larger than available memory.

setvbuf() does not seem to have an effect on Windows.

Make sure everything gets logged right away.  No delays because
stdio's buffer is not yet full.

Without MEM_COMMIT, the reserved address space is not accessible, and
MPD crashes.

plugin was incorrect.

Works around assertion failure due to something that appears to be a
(minor) FFmpeg bug.

Fixes bogus assertion failure.

SocketMonitor::Cancel() does not actually unregister the socket; it
