6fd52d671d Acceptance test: add "boot_linux" tests
This acceptance test, validates that a full blown Linux guest can
successfully boot in QEMU.  In this specific case, the guest chosen is
Fedora version 31.

 * x86_64, pc-i440fx and pc-q35 machine types, with TCG and KVM as
   accelerators

 * aarch64 and virt machine type, with TCG and KVM as accelerators

 * ppc64 and pseries machine type with TCG as accelerator

 * s390x and s390-ccw-virtio machine type with TCG as accelerator

The Avocado vmimage utils library is used to download and cache the
Linux guest images, and from those images a snapshot image is created
and given to QEMU.  If a qemu-img binary is available in the build
directory, it's used to create the snapshot image, so that matching
qemu-system-* and qemu-img are used in the same test run.  If qemu-img
is not available in the build tree, one is attempted to be found
installed system-wide (in the $PATH).  If qemu-img is not found in the
build dir or in the $PATH, the test is canceled.

The method for checking the successful boot is based on "cloudinit"
and its "phone home" feature.  The guest is given an ISO image with
the location of the phone home server, and the information to post
(the instance ID).  Upon receiving the correct information, from the
guest, the test is considered to have PASSed.

This test is currently limited to user mode networking only, and
instructs the guest to connect to the "router" address that is hard
coded in QEMU.

To create the cloudinit ISO image that will be used to configure the
guest, the pycdlib library is also required and has been added as
requirement to the virtual environment created by "check-venv".

The console output is read by a separate thread, by means of the
Avocado datadrainer utility module.

db5adeaa84 build-sys: clean up flags included in the linker command line
Some of the CFLAGS that are discovered during configure, for example
compiler warnings, are being included on the linker command line because
QEMU_CFLAGS is added to it.  Other flags, such as the -m32, appear twice
because they are included in both QEMU_CFLAGS and LDFLAGS.  All this
leads to confusion with respect to what goes in which Makefile variables
(and we have plenty).

So, introduce QEMU_LDFLAGS for flags discovered by configure, following
the lead of QEMU_CFLAGS, and stop adding to it:

1) options that are already in CFLAGS, for example "-g"

2) duplicate options

At the same time, options that _are_ needed by both compiler and linker
must now be added to both QEMU_CFLAGS and QEMU_LDFLAGS, which is clearer.
This is mostly -fsanitize options.  For now, --extra-cflags has this behavior
(but --extra-cxxflags does not).

Meson will not include CFLAGS on the linker command line, do the same in our
build system as well.

3b35388358 travis.yml: Detach build and test steps
Currently build and test commands are a single step in a
Travis's `script` block. In order to see the output
of the tests one needs to scroll down the log to find where
the build messages ended and the limit is not clear. If
they were in different steps then Travis would print the
result build command, which can be easily grep'ed.

So this change is made to detach those commands
to ease the visualization of the output.

Note that all steps on the `script` block is executed regardless
if one previous has failed. To overcome it, let's save the
return code of the build then check whether succeed or failed on
the test step.

9c5941a96a travis.yml: Enable builds on arm64, ppc64le and s390x
Travis recently added the possibility to test on these architectures,
too, so let's enable them in our travis.yml file to extend our test
coverage.

Unfortunately, the libssh in this Ubuntu version (bionic) is in a pretty
unusable Frankenstein state and libspice-server-dev is not available here,
so we can not use the global list of packages to install, but have to
provide individual package lists instead.

Also, some of the iotests crash when using "dist: bionic" on arm64
and ppc64le, thus these two builders have to use "dist: xenial" until
the problem is understood / fixed.

So far we only have compile coverage for tci. But since commit
2f160e0f97 ("tci: Add implementation
for INDEX_op_ld16u_i64") has been included now, we can also run the
"tcg" and "qtest" tests with tci, so let's enable them in Travis now.
Since we don't gain much additional test coverage by compiling all
targets, and TCI is broken e.g. with the Sparc targets, we also limit
the target list to a reasonable subset now (which should still get us
test coverage by tests/boot-serial-test for example).

61ac3dcc15 travis.yml: Test the release tarball
Add a job to generate the release tarball and build/install few
QEMU targets from it.

Ideally we should build the 'efi' target from the 'roms' directory,
but it is too time consuming.

This job is only triggered when a tag starting with 'v' is pushed,
which is the case with release candidate tags.
