tests/Makefile had a mix of TAB vs. 8-space indentation; given
that it is a Makefile, TAB is more idiomatic even though in these
particular cases the choice of whitespace didn't matter.

There are problems with unreliability in "make check" which still need
to be tracked down. As the tests are broadly the same for all targets if
added one explicit target to the matrix to run it. However this does
build all softmmu targets to ensure they at least "run"

A significant portion of the build time is spent initialising all the
sub-modules we use in the source tree. Often this is almost as long as
the build itself. By pre-seeding the .git/modules tree this will
hopefully improve things.

At the same time I've grouped the $ARCH-linux-user and $ARCH-softmmu

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.

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.

Install the ./trace-events file into the data directory.  This file
contains the list of trace events that were built into QEMU at
compile-time.

The file is a handy reference for the set of trace events that the QEMU
binary was built with.  It is also needed by the simpletrace.py tool
that parses binary trace data either emitted from QEMU when built with
--enable-trace-backend=simple or by the SystemTap simpletrace script
that QEMU provides.
