Commit f26e428d fixed compilation
with --enable-vnc-png, but broke it with --enable-vnc-png.

The breakage is caused by pngconfig.h which checks whether
setjmp.h was already included and fails because qemu-common.h
includes setjmp.h.

The check is disabled by defining PNG_SKIP_SETJMP_CHECK.

If I start qemu with:

  # qemu -hda disks/test.img -enable-kvm -m 1G -snapshot \
         -device virtio-serial \
         -chardev socket,host=localhost,port=1234,server,nowait,id=foo \
         -device virtserialport,chardev=foo,name=org.qemu.guest_agent

I get a segfault when booting a Fedora 14 guest. The backtrace says:

  Program terminated with signal 11, Segmentation fault.
    #0  0x0000000000420850 in handle_control_message (vser=0x3732bd0, buf=0x2c173e0, len=8) at /home/lcapitulino/src/qmp-unstable/hw/virtio-serial-bus.c:335
    335     info = DO_UPCAST(VirtIOSerialPortInfo, qdev, port->dev.info);

What's happening is VIRTIO_CONSOLE_DEVICE_READY is a message for the
whole device, not for an individual port. So port is NULL. This bug was
introduced by commit a15bb0d6.

This commit fixes that by making the port returned by find_port_by_id()
be used only by the VIRTIO_CONSOLE_PORT_READY and
VIRTIO_CONSOLE_PORT_OPEN messages.

Use stack instead of temp_buf array in CPUState for TCG temps.

On Sparc64, stack pointer is not aligned but there is a fixed bias of 2047,
so don't try to enforce alignment.

Except for specific cases where the use of %esp changes the encoding of
the instruction, it's cleaner to use TCG_REG_CALL_STACK instead of
TCG_REG_ESP.
Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

The code for stack allocation for call arguments is way too simplistic
to actually work on targets with non-trivial stack allocation policies,
e.g. ppc64. We've also already allocated TCG_STATIC_CALL_ARGS_SIZE worth
of stack for calls which should be well more than any helper needs.

Remove broken dynamic stack allocation code and replace it with an assert.
Should dynamic stack allocation ever be needed again, target specific
functions should be added.

Thanks to Richard Henderson for the analysis.

Make functions take a parameter for CPUState instead of relying
on global env. Pass CPUState pointer to TCG prologue, which moves
it to AREG0.

Thanks to Peter Maydell and Laurent Desnogues for the ARM prologue

Pass CPUState to do_interrupt(). This is needed by later patches.

It would be cleaner to move the function to helper.c, but there are
a few dependencies between do_interrupt() and other functions.

Several x86 specific functions are called from cpu-exec.c with the
assumption that global env register is valid. This will be changed
later, so make the functions use caller supplied CPUState parameter.

It would be cleaner to move the functions to helper.c, but there are
quite a lot of dependencies between do_interrupt() and other functions.

Add helpers for svm_check_intercept() and cpu_cc_compute_all() instead
of calling the helper (which uses global env, AREG0) directly.

do_interrupt() was mixing CPUState pointer passed from caller
and global env (AREG0).

Fix by moving the function to helper.c. Introduce a helper for calling
change_pstate() safely from outside of execution context.
