CRISv10 cores (unlike v32) do not take any interrupts while delayed
jumps are pending (delay slots).

c227f0995e 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.

This reverts commit 99a0949b72.

72cf2d4f0e Fix sys-queue.h conflict for good
Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc923584,
f40d753718,
96555a96d7 and
3990d09adf but the fixes were fragile.

Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.

0b5c1ce846 cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signal
handle_cpu_signal is very nearly copy-paste code for each target, with a
few minor variations.  This patch sets up appropriate defaults for a
generic handle_cpu_signal and provides overrides for particular targets
that did things differently.  Fixing things like the persistent (XXX:
use sigsetjmp) should now become somewhat easier.

Previous comments on this patch suggest that the "activate soft MMU for
this block" comments refer to defunct functionality.  I have removed
such blocks for the appropriate targets in this patch.
