Pulseaudio normally assumes that when the server wants it, the client
can generate the audio samples and send it right away.  Unfortunately
this is not the case with QEMU -- it's up to the emulated system when
does it generate the samples.  Buffering the samples and sending them
from a background thread is just a workaround, that doesn't work too
well.  Instead enable pa's compatibility support and let pa worry about
the details.

This means you should probably stop using -soundhw (as it doesn't allow
you to specify any options) and add the device manually with -device.
The exception is pcspk, it's currently not possible to manually add it.
To use it with audiodev, use something like this:

    -audiodev id=foo,... -global isa-pcspk.audiodev=foo -soundhw pcspk

Audio functions no longer access glob_audio_state, instead they get an

Remove glob_audio_state from functions, where possible without breaking
the API.  This means that most static functions in audio.c now take an
AudioState pointer instead of implicitly using glob_audio_state.  Also
included a pointer in SWVoice*, HWVoice* structs, so that functions
dealing them can know the audio state without having to pass it around
separately.

This is required in order to support multiple simultaneous audio
backends (added in a later commit).

When preallocating an encrypted qcow2 image, it just lets the protocol
driver write data and then does not mark the clusters as zero.
Therefore, reading this image will yield effectively random data.

As such, we have not fulfilled the promise of always writing zeroes when
preallocating an image in a while.  It seems that nobody has really
cared, so change the documentation to conform to qemu's actual behavior.

vpc is not really a passthrough driver, even when using the fixed
subformat (where host and guest offsets are equal).  It should handle
preallocation like all other drivers do, namely by returning
DATA | RECURSE instead of RAW.

There is no tangible difference but the fact that bdrv_is_allocated() no
longer falls through to the protocol layer.
