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.

 -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).

Revert r5636 to fix icount on hosts w/o high-res clocks

Changeset r5636 changed the timers to run in the alarm callback.  The
alarm callback can only be called as frequently as the host alarm timer
fires.  For older Linux hosts and possibly non-Linux hosts, this can be
as high as a 1ms granularity.

icount calculates the select timeout based on the next deadline and
select is usually capable of sleeping for a short period of time than
alarm timer granularity.  This means that changing the timer callbacks
to be based on alarm firing caused timers to fire much later than they
ought to when using icount.

vga optimization (Glauber Costa)

Hypervisors like KVM perform badly while doing mmio on
a loop, because it'll generate an exit on each access.
This is the case with VGA, which results in very bad
performance.

In this patch, we map the linear frame buffer as RAM,
make sure it has dirty region tracking enabled, and then
just let the region to be written.
