linux-user: Support for restarting system calls for Alpha targets
...
Update the Alpha main loop and sigreturn code:
* on TARGET_ERESTARTSYS, wind guest PC backwards to repeat syscall insn
* handle TARGET_QEMU_ESIGRETURN in the main loop as the indication
that the main loop should not touch any guest CPU state

alpha-linux-user: Implement signals.
...
Move userland PALcode handling into linux-user main loop so that
we can send signals from there. This also makes alpha_palcode.c
system-level only, so don't build it for userland. Add defines
for GENTRAP PALcall mapping to signals.

Revert "Get rid of _t suffix"
...
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.
