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.

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.

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
change.

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

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

Fix by moving the function to helper.c. Introduce a helper for calling

OSStatus type is defined as SInt32. That's signed int on __LP64__ and
signed long otherwise.
Since it is an explicit 32-bit-width type, cast to corresponsing POSIX type
and use PRId32 format specifier. This avoids a warning on ppc64.

Diagnose the case where the user asked for a NIC via "-net nic"

user asked for two NICs but the board only supports one). Note
that this diagnostic doesn't apply to NICs created through -device,

Don't warn about the default network setup that you get if no command line
-net options are specified.  There are two cases that we would otherwise
complain about:

(1) board doesn't support a NIC but the implicit "-net nic" requested one
(2) CONFIG_SLIRP not set, so the implicit "-net nic" sets up a nic that
isn't connected to anything

When running kvm-autotest, fputc() is often the second highest (sometimes #1)
function showing up in a profile.  This is due to fputc() locking the file
for every byte written.

Optimize by buffering a line's worth of pixels and writing that out in a
single call.
