linux-user: Support for restarting system calls for x86 targets
Update the x86 main loop and sigreturn code:
* on TARGET_ERESTARTSYS, wind guest PC backwards to repeat syscall insn
* set all guest CPU state within signal.c code rather than passing it
back out as the "return code" from do_sigreturn()
* handle TARGET_QEMU_ESIGRETURN in the main loop as the indication
that the main loop should not touch EAX
