Allow monitor interaction when using migrate -exec
All,
I've recently been playing around with migration via exec. Unfortunately,
when starting the incoming qemu process with "-incoming exec:cmd", it suffers
the same problem that -incoming tcp used to suffer; namely, that you can't
interact with the monitor until after the migration has happened. This causes
problems for libvirt usage of -incoming exec, since libvirt expects to be able
to access the monitor ahead of time. This fairly simple patch allows you to
access the monitor both before and after the migration has completed using exec.

serial: fix lost character after sysrq
After creating an automated regression test to test the sysrq

The problem is that the qemu sets the LSR_DR (data ready) bit on a
serial break. The automated tests can send a break and the sysrq
character quickly enough that the qemu serial fifo has a real
character available. When there is valid character in the fifo, it
gets consumed by the serial driver in the guest OS.

Convert qemu-img create to new bdrv_create
This patch changes qemu-img to actually use the new bdrv_create interface. It
translates the old-style qemu-img options which have been bdrv_create2
parameters or flags so far to option structures. As the generic approach, it
introduces an -o option which accepts any parameter the driver knows.

Convert all block drivers to new bdrv_create
Now we can make use of the newly introduced option structures. Instead of
having bdrv_create carry more and more parameters (which are format specific in
most cases), just pass a option structure as defined by the driver itself.
bdrv_create2() contains an emulation of the old interface to simplify the
transition.

Create qemu-option.h
This patch creates a new header file and the corresponding implementation file
for parsing of parameter strings for options (like used in -drive). Part of
this is code moved from vl.c (so qemu-img can use it later).
The idea is to have a data structure describing all accepted parameters. When
parsing a parameter string, the structure is copied and filled with the
parameter values.

Eliminate --disable-gfx-check and make VNC default when SDL not available
--disable-gfx-check predates VNC server support. It made sense back then
because the only thing you could do without SDL was use -nographic mode or
similar tricks. Since this is a very advanced mode of operation, gfx-check
provided a good safety net for casual users.
A casual user is very likely to use VNC to interact with a guest. In fact, it's
often frustrating to install QEMU on a server and have to specify
disable-gfx-check when you only want to use VNC.
This patch eliminates disable-gfx-check and makes SDL behave like every other
optional dependency. If SDL is not available, instead of failing ungracefully
if no special options are specified, we default to -vnc localhost:0,to=99.
When we do default to VNC, we also print a message to tell the user that we've
done this include which port we're currently listening on.
