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.

Refactor how display drivers are selected
My previous commit, f92f8afebe, broke -vnc (spotted by Glauber Costa). This

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.
