Add basic audio functionality to vnc.c

This allows among other things to capturing A/V of running
guests. Ad-hoc client that does this (via script that invokes ffmpeg)

Reset the key modifiers upon client connect

VNC should not maintain modifer state upon reconnects With some window
managers/vnc clients it will only see a key down event for a modifier
followed by immediate disconnect(think Alt-F4), with a net effect of
subsequently connected clients operating as if the modifier was never
released.

Exclude unix: from vnc call to unix_listen() (Ryan Harper)

When using an existing unix socket like:

 -vnc unix:/tmp/file1Y2nY2

qemu fails to bind a unix socket because the vnc call to unix_listen includes
the unix: prefix and stores that in the unix.sun_path.  The fix is to not pass
in unix: for the filename (same way qemu-char.c does it).

Change order of metadata update to prevent loosing guest data because of unexpected exit (Gleb Natapov)

Currently the order is this (during cow since it's the interesting case):
1. Decrement refcount of old clusters
2. Increment refcount for newly allocated clusters
3. Copy content of old sectors that will not be rewritten
4. Update L2 table with pointers to new clusters
5. Write guest data into new clusters (asynchronously)

There are several problems with this order. The first one is that if qemu
crashes (or killed or host reboots) after new clusters are linked into L2
table but before user data is written there, then on the next reboot guest
will find neither old data nor new one in those sectors and this is not
what gust expects even when journaling file system is in use.  The other
problem is that if qemu is killed between steps 1 and 4 then refcount
of old cluster will be incorrect and may cause snapshot corruption.

The patch change the order to be like this:
1. Increment refcount for newly allocated clusters
2. Write guest data into new clusters (asynchronously)
3. Copy content of old sectors that were not rewritten
4. Update L2 table with pointers to new clusters
5. Decrement refcount of old clusters

Unexpected crash may cause cluster leakage, but guest data should be safe.
