dc7eea67a1 linux-user: fix signal.c warning 
This patch fixes:

linux-user/signal.c:1403: warning: no previous prototype for 'do_sigreturn_v1'
linux-user/signal.c:1473: warning: no previous prototype for 'do_sigreturn_v2'
linux-user/signal.c:1511: warning: no previous prototype for 'do_rt_sigreturn_v1'
linux-user/signal.c:1552: warning: no previous prototype for 'do_rt_sigreturn_v2'

by making the appropriate functions static.

7d99a001df Add noreturn function attribute 
Introduce noreturn attribute and attach it to cpu_loop_exit as well as
interrupt/exception helpers for i386. This avoids a bunch of gcc4
warnings.

[ Note that this patch comes with a workaround to include qemu-common.h
even in cases where is currently causes conflicts with dyngen-exec.h.
I've been told that these conflicts will get resolved in the future
(/me will try to have a look as well - as time permits). ]

eaa449b940 Fix qemu endless loop when raising a SIGSEGV/SIGBUS signal with gdbstub in user emulation 
When a SIGSEGV signal is raised in user mode emulation the current
test to know whether the signal is sent by the kernel is wrong :

info->si_code == SI_KERNEL

according to /usr/include/bits/siginfo.h it should be

info->si_code > 0

ca587a8ebd User-mode GDB stub improvements - handle signals 
Handle signals in the user-mode GDB stub.  Report them to GDB, and
allow it to change or cancel them.  Also correct the protocol numbering;
it happens to match Linux numbering for SIGINT and SIGTRAP, but that's
just good fortune.
