f963e4d0ca gtk ui: unbreak spice
Merge of the gtk ui brought a initialitation order issue for spice:
The using_spice variable isn't set yet when checked, leading to the
default UI being activated (additionally to spice remote access).

Let's set display_remote when we find a -spice switch on the command
line, like we do for vnc.

08f4a0f7ee target-ppc: Fix SUBFE carry
While ~T0+T1+CF = T1-T0+CF-1 is true for the low 32-bits,
it does not produce the correct carry-out to bit 33.  Do

While T0+~T1+CF = T0-T1+CF-1 is true for the low 32-bits,
it does not produce the correct carry-out to bit 33.  Do
exactly what the manual says.

Using the ~T1 makes the add and subtract code paths nearly
identical, so have sbc_CC use adc_CC.

8c3ac601bd arm/translate.c: Fix adc_CC/sbc_CC implementation
commits 49b4c31efc and
2de68a4900 reworked the implementation of adc_CC
and sub_CC. The new implementations (on the TCG_TARGET_HAS_add2_i32 code path)
are incorrect. The new logic is:

CF:NF = 0:A +/- 0:CF
CF:NF = CF:A +/- 0:B

The lower 32 bits of the intermediate result stored in NF needs to be passes
into the second addition in place of A (s/CF:A/CF:NF):

CF:NF = 0:A +/- 0:CF
CF:NF = CF:NF +/- 0:B

This patch fixes the issue.

6ab7e5465a Replace all setjmp()/longjmp() with sigsetjmp()/siglongjmp()
The setjmp() function doesn't specify whether signal masks are saved and
restored; on Linux they are not, but on BSD (including MacOSX) they are.
We want to have consistent behaviour across platforms, so we should
always use "don't save/restore signal mask" (this is also generally
going to be faster). This also works around a bug in MacOSX where the
signal-restoration on longjmp() affects the signal mask for a completely
different thread, not just the mask for the thread which did the longjmp.
The most visible effect of this was that ctrl-C was ignored on MacOSX
because the CPU thread did a longjmp which resulted in its signal mask
being applied to every thread, so that all threads had SIGINT and SIGTERM
blocked.

The POSIX-sanctioned portable way to do a jump without affecting signal
masks is to siglongjmp() to a sigjmp_buf which was created by calling
sigsetjmp() with a zero savemask parameter, so change all uses of
setjmp()/longjmp() accordingly. [Technically POSIX allows sigsetjmp(buf, 0)
to save the signal mask; however the following siglongjmp() must not
restore the signal mask, so the pair can be effectively considered as
"sigjmp/longjmp which don't touch the mask".]

For Windows we provide a trivial sigsetjmp/siglongjmp in terms of
setjmp/longjmp -- this is OK because no user will ever pass a non-zero
savemask.

The setjmp() uses in tests/tcg/test-i386.c and tests/tcg/linux-test.c
are left untouched because these are self-contained singlethreaded
test programs intended to be run under QEMU's Linux emulation, so they
have neither the portability nor the multithreading issues to deal with.
