At the same time I've grouped the $ARCH-linux-user and $ARCH-softmmu
builds together (hoping FS cache helps) and grouped all $ARCH-softmmu
only builds into one target. This reduces the build matrix slightly
which will hopefully help with build times.

Since 3687d532 we've been unconditionally adding qom-test to our qtests
for every arch. However, some archs inherit their tests from Makefile
variables for other archs, such as i386/x86_64,
microblaze/microblazeel, and xtensa/xtensaeb. Since these are evaluated
in a lazy manner, we ultimately end up adding qom-test twice.
In the case x86_64, where we have a large number of machine types that
we rerun qom-test for, this has lead to a fairly noticeable increase
in the overall run-time of `make check` (78s vs. 42s on my machine).
Similar speed-ups are visible for other such archs, but not nearly as
significant.
Fix this by only adding qom-test to an arch's test list if it's not
already present.

since commit 7dda5dc82a ("migration: initialize RAM to zero") the
guest memory is defined zero. No need to call valgrind on guest memory.

This patch fixes migration by extending do_vapic_enable function. This function
called vapic_enable which read cpu number from the guest memory. When cpu
number could not be read, vapic was not enabled while loading the VM state.
This patch adds required code for cpu_number=0 to do_vapic_enable function,
because it is called only when cpu_number=0.

Add the termination signals SIGINT, SIGHUP and SIGTERM to the
list of signals which we handle synchronously via a signalfd.
This avoids a race condition where if we took the SIGTERM
in the middle of qemu_shutdown_requested:
int r = shutdown_requested;
[SIGTERM here...]
shutdown_requested = 0;
then the setting of the shutdown_requested flag by
termsig_handler() would be lost and QEMU would fail to
shut down. This was causing 'make check' to hang occasionally.
