These headers all use TARGET_SIGNAL_H as header guard symbol. Reuse
of the same guard symbol in multiple headers is okay as long as they
cannot be included together.
Since we can avoid guard symbol reuse easily, do so: use guard symbol
$target_TARGET_SIGNAL_H for linux-user/$target/target_signal.h.

Update the Microblaze 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 on sigreturn
* handle TARGET_QEMU_ESIGRETURN in the main loop as the indication
that the main loop should not touch any guest CPU state
Note that this in passing fixes a bug where we were corrupting
the guest r[3] on sigreturn with the guest's r[10] because
do_sigreturn() was returning env->regs[10] but the register for
syscall return values is env->regs[3].

In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.
This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

Some not so obvious bits, slirp and Xen were left alone for the time
being.
