The problems I had were related to the OSS driver and USB
device I was using.  The problems existed even with the old
busy-waiting scheme enabled.

OSS  - Bithead USB     => bad
ALSA - Bithead USB     => OK
OSS  - Onboard i8x0    => OK
ALSA - Onboard i8x0    => OK

bad - slow shutdown, pauses, dropped audio after pause/resume

Until we can fix it properly (or replace it with a cleaner event
system), I don't want this in trunk.  Currently there are
strange pauses when queueing and during shutdown that I can't
seem to figure out right away.

This way we'll avoid listening on fd=0 and have a better
chance of having fd=0 as /dev/null

We redirect stdin to /dev/null to work around a libao bug, but
this bug has been fixed in libao since 2003 (according to jat).

However, there are likely other bugs in other libraries (and
even our code!) that handle fd=0 incorrectly and I'd rather not
take the risk[1].  So So it's easiest to just keep
fd=0==/dev/null for now...

The host buffer that hostname pointed to is no longer on the
stack by the time the SECURE() message is printed.  So make it
static and thus accessible to all.  We won't be calling this
stuff in the middle of a child process/thread/task, so there's
no

Also, hostname is a constant string we shouldn't modify, so mark
it as const char *.

For the default: case, just use the error message that libFLAC
provides instead of using something ambiguous.  Also, this gets
rid of long lines in the code, making it easier to digest.

Of course, we save ~100 bytes of text space in the process :)

As unfortunate as it is to remove such useful debugging messages, it's
necessary to fix a potential deadlock with signal handling.  A bunch of
functions the debug functions call aren't safe to call from a signal
handler.  There are some alternate solutions, but they're neither pretty
nor simple.  So just remove them entirely for now.

Using SECURE once without a \n, and again with one, results in a timestamp
mid-line.  Let's not do that.

as with the stop command, this will cause the player and decoder
to suspend and not wake up hundreds of times a second to poll
a variable for wakeup.  This will reduce power consumption
on some CPUs while mpd is paused and not playing.

tests:

pause && unpause => OK

pause && stop && play => OK

pause && exit && restart w/statefile && unpause => OK

pause && block sound device && \
unpause => failed to open sound device \
=> still paused and suspended => unblock sound device &&
unpause => OK (playing)

In all cases, the player process releases the audio device
when paused before going into the suspended state.

This attribute was set in log.c, but not exported to other
modules in log.h

This allows us to remove some unneccessary variable
initializations that were added in r6277.  I did
audioOutput_shout.c a bit differently, to avoid some
jumps.

Parse ReplayGain info in LAME tags and use it if no ID3v2 ReplayGain tags
are found.  This is currently a bit unsafe, as apparently some LAME tags
have bogus ReplayGain values.  But I'm finding a lot of MP3s with valid
LAME tags that fail the LAME tag CRC check.  So until I figure out why
that's happening, it's an unreliable method for checking if the LAME tag is
valid.

A big thanks to tmz for writing the original patch.

Currently, if we start decoding while the pause flag is set, we open the
audio device and leave it opened, blocking other apps from using it.  The
obvious thing to do is to not open the audio device if the pause flag is
set, but the open call also sets the audio format.  Therefore I'm leaving
the open call in, and just closing it immediately afterwards if the pause
flag is set.

preventing connection attempts from blocking playback on local outputs.

Previously, the warning log was only flushed if creating the db or logging
to stdout.  This meant that under normal circumstances (no db creation,
logging to files) the warning log was never flushed.  This caused a bug
when a warning was printed for each call to the status command where the
warning buffer would grow endlessly, eventually using more and more CPU to
reallocate it.

opening the file.  Thanks again to Kodest for figuring this one out.

This ReplayGain code is currently disabled because WavpackGetTagItem can't
seem to find replaygain_* fields in APEv2 tags (which is how wvgain stores
ReplayGain values).  Additionally, because APEv2 tags are stored at the end
of the file, this code is only implemented for regular files and not HTTP
streams.  Using HTTP seeking it *may* be possible to implement it for both.

Only wavpack implements both fileDecodeFunc and streamDecodeFunc, and it's
fileDecodeFunc provides more functionality.  So try using that first.

This commit also fixes a bug where the plugin test loop wouldn't break once
a suitable plugin was found if it used fileDecodeFunc.
