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.

The shout plugin will now feign playback until the connect timeout is hit,
preventing connection attempts from blocking playback on local outputs.
Note that this patch is very different from remiss' original one.

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.

Turns out the fix was as simple as specifying the OPEN_TAGS flag when
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.

all.  So let's just be lazy.

if the clock ticks right after we get the start time and the timeout is
only one second, we'll still wait a full second instead of returning
immediately.

pretending to play while we wait for the connection to timeout.  This
removes the need for timers, and thus removes the now unnecessary
timer_get_runtime_* function(s) from the timer code.

The changes made compared to the pre-patch shout plugin are:
* Block while connecting, timing out after 2 seconds.
* Close the device, and not just the connection, if play returns -1.
* Remove sd->last_err (it's always assigned before use).
* Some minor cleanups.

outputs, which is actually desired behaviour.  This way if the shout server
takes a while to respond, the shout output can block until connected
without messing up other audio outputs.

leave it in that state.  Likewise, if an audio output is in state
DEVICE_ON, and reopening the device due to a format change fails, change it
to state DEVICE_ENABLE.  This will prevent flushAudioBuffer from even
attempting to play audio on a closed device (even though it would fail
anyway).

top depending on !quit, which doesn't set it anywhere before the if (quit)
block is reached, and the inner one which doesn't set quit at all.  Since
it's a local variable and can't be modified externally, it'll never be hit.

This should resolve some of the timing issues experienced after switching from blocking to non-blocking shout api
* Wait ten seconds before declearing the shout server unreachable
* Fix a state where it would never attempt to connect if it had previously failed

It isn't perfect yet, but I'd like some testing on it from other setups
