71b9b0ca5b Partially revert e20a8dff4c
From Paul Brook:

 "the fdc is tied to the ISA DMA engine. We don't currently have a target
  independent method of handling inter-device data transfer."

79eb76ade2 Revert "Fix arm-softmmu breakage"
This reverts commit ec6bd8dea7.

This broke any target that uses virtio.  Virtio devices live in libhw and
without whole-archive, the constructors will never be called for virtio.

0c257437b2 Introduce is_default field for QEMUMachine
f80f9ec changed the order that machines are registered which had the effect of
changing the default machine.  This changeset introduces a new is_default field
so that machine types can declare that they are the default for an architecture.

993fbfdb1b Refactor how display drivers are selected
My previous commit, f92f8afebe,  broke -vnc (spotted by Glauber Costa).  This
is because it's necessary to tell when the no special display parameters have
been passed and default to SDL or VNC appropriately.

This refactors the display selection logic to be less complicated which has
the effect of fixing the regression mentioned above.

f92f8afebe 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.

9ed415b28b initialize struct sigevent before timer_create
When qemu is run under valgrind, valgrind shows the following output
on exit:

==3648== 1 errors in context 2 of 2:
==3648== Syscall param timer_create(evp) points to uninitialised byte(s)
==3648==    at 0x54E936A: timer_create (in /lib/librt-2.9.so)
