.travis.yml: migrate to container builds

This moves the Travis tests from the legacy VM infrastructure (which
only seems to run 5-6 jobs at once) to the new container based approach.

The principle difference is there is no sudo in the containers so all
packages are installed using the apt add-on. This means one of the build
combinations can be dropped as it was only for checking the build with
additional packages.

.travis.yml: Run make check for all targets, not just some

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.

For example, you can compile QEMU with:

Where 'ftrace' can be handy for having an in-flight record of events, and 'dtrace' can be later used to extract more information from the system.

This patch allows having both available without recompiling QEMU.

I'm trying to avoid spamming the IRC channel (not overly likely as
builds take a while). So failure will always be reported but if the
build continues to work then the IRC notifications will be quiet.

Note any GitHub based repository with Travis enabled will use this
notification. If it proves to be too spammy we may want to ask users not
to use Travis themselves although this seems sub-optimal.

.travis.yml: basic compile and check recipes

This adds a build matrix definition for travis-ci.org continuous
integration service. It is usable on any public repository hosted on
GitHub. Once you have created an account signed into Travis you can
enable it on selected projects via travis-ci.org/profile. Alternatively
you can configure the service hooks on GitHub via the repository
Settings tab,then Service Hooks and selecting Travis.

Once setup Travis will automatically test every push as well as any pull
requests submitted to that repository.

The build matrix is currently split by target architecture (see TARGETS
environment variable) because a full build of QEMU can take some time.
This way you get quick feedback for any obvious errors. The additional
environment variables exist to allow additional builds to tweak the
environment. These are:

EXTRA_CONFIG - extra terms passed to configure
EXTRA_PKGS - extra dev packages to install
TEST_CMD - default "make check", can be overridden

I've confined the additional stuff to x86/x86_64 for convenience.

As Travis supports clang the main builds are done twice (once for gcc
and once for clang). However clang is disabled for the debug/trace
builds for the purposes of brevity.

Other wrinkles:

* The lttng user-space tracing back-end is disabled
(it is currently horribly broken)
* The ftrace back-end doesn't run "make check"
(it requires a mounted debugfs to work)
* There are two debug enabled build (with and without TCG interpreter)
