The test doesn't check that the output makes any sense, only that QEMU
survives. Useful since we've had an astounding number of crash bugs
around there.
In fact, we have a bunch of them right now: a few devices crash or
hang, and some leave dangling pointers behind. The test skips testing
the broken parts. The next commits will fix them up, and drop the
skipping.

New convenience function hmp() to facilitate use of
human-monitor-command in tests. Use it to simplify its existing uses.
To blend into existing libqtest code, also add qtest_hmpv() and
qtest_hmp(). That, and the egregiously verbose GTK-Doc comment format
make this patch look bigger than it is.

We want to run qom-test for every architecture, without having to
manually add it to every architecture's list of tests. Commit 3687d53
accomplished this by adding it to every architecture's list
automatically.
However, some architectures inherit their tests from others, like this:
check-qtest-x86_64-y = $(check-qtest-i386-y)
check-qtest-microblazeel-y = $(check-qtest-microblaze-y)
check-qtest-xtensaeb-y = $(check-qtest-xtensa-y)
For such architectures, we ended up running the (slow!) test twice.
Commit 2b8419c attempted to avoid this by adding the test only when
it's not already present. Works only as long as we consider adding
the test to the architectures on the left hand side *after* the ones
on the right hand side: x86_64 after i386, microblazeel after
microblaze, xtensaeb after xtensa.
Turns out we consider them in $(SYSEMU_TARGET_LIST) order. Defined as
SYSEMU_TARGET_LIST := $(subst -softmmu.mak,,$(notdir \
$(wildcard $(SRC_PATH)/default-configs/*-softmmu.mak)))
On my machine, this results in the oder xtensa, x86_64, microblazeel,
microblaze, i386. Consequently, qom-test runs twice for microblazeel
and x86_64.
Replace this complex and flawed machinery with a much simpler one: add
generic tests (currently just qom-test) to check-qtest-generic-y
instead of check-qtest-$(target)-y for every target, then run
$(check-qtest-generic-y) for every target.

This is legal; the MemoryRegion will simply unreference all the

However, it requires a bit of care to avoid an infinite loop.
Finalizing a memory region cannot trigger an address space update,

might trigger a spurious update: avoid that by resetting mr->enabled

for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form

ed173cb ".travis.yml: remove "make check" from main matrix" stopped running
make check for all the Travis build targets for various reasons. It
continued to run make check on one Travis build, which builds for a big
list of all (? nearly all) our supported softmmu targets.
Unfortunately, due to a spacing / quoting error it only actually builds for
the alpha, arm, aarch64 and cris targets. Specifically, the list of
targets is split over several lines. Even with YAML folding, this will
leave spaces in the list, meaning $TARGETS won't have the value we need.
I had a look at the YAML spec and I couldn't quickly see a way of splitting
the list so that it doesn't end up with spaces, so this patch fixes the
problem by putting the whole list on one huge line.

We currently pre-compute an worst case code size for any TB, which
works out to be 122kB. Since the average TB size is near 1kB, this
wastes quite a lot of storage.
Instead, check for overflow in between generating code for each opcode.
The overhead of the check isn't measurable and wastage is minimized.
