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."

This reverts commit ec6bd8de.

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

f80f9ec9 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.

My previous commit, f92f8afe,  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.

This cleans up quite a lot of #ifdefs, extern variables, and other ugliness.

 --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.

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)
==3648==    by 0x405DCF: dynticks_start_timer (vl.c:1549)
==3648==    by 0x40A966: main (vl.c:1726)

==3648==  Uninitialised value was created by a stack allocation
==3648==    at 0x405D60: dynticks_start_timer (vl.c:1534)

This patch is a simple fix to remove this potential problem.

This fixes a SIGSEGV error on qemu exit.

Here is the valgrind output related to this error

==3648== Process terminating with default action of signal 11 (SIGSEGV)
==3648==  Access not within mapped region at address 0x8
==3648==    at 0x40636B: host_alarm_handler (vl.c:1345)

==3648==    by 0x5B4B5AC: (below main) (in /lib/libc-2.9.so)

This simple fix check for a valid pointer as host_alarm_handler is
also called after alarm_timer is released in the exit path.

initrd must be kept on the memory area below 4g. By not doing this,
we're seeing guests break while using -initrd and values of -mem
superior to 4096.

This text is no longer accurate. After the patch is applied, the
generated version at http://www.nongnu.org/qemu/qemu-doc.html should be
regenerated.

This patch is also a candidate for the stable branch. (The URL above is
probably generated from the stable branch anyways, so maybe it goes
without saying.)

The only target dependency for most hardware is sizeof(target_phys_addr_t).
Build these files into a convenience library, and use that instead of
building for every target.

Remove and poison various target specific macros to avoid bogus target
dependencies creeping back in.

Big/Little endian is not handled because devices should not know or care
about this to start with.

If the target only has a 32-bit physical address space then
the code to map >4G ram breaks horribly, and causes compiler warnings.

Depending on the order in which atexit handlers are called SDL might
try to join on an audio thread without said thread ever being notified
that it must stop, hence QEMU will forever block in pthread_join call.
