In case the string doesn't fit into the buffer snprintf returns the size
it would need, so len can be larger than the buffer. Fix this by simply

There is some additional information about the 3270 support in our Wiki
at https://wiki.qemu.org/Features/3270 - so let's include this information
into the main documentation now to have one single source of information
(the Wiki page could later be removed).
While at it, I also shortened the lines of the first example a little bit.
Otherwise they showed up with a horizontal scrollbar in my Firefox browser.

This script is intended to be used right after a push to a branch.
By default, it will look for the pipeline associated with the commit
that is the HEAD of the *local* staging branch. It can be used as a
one time check, or with the `--wait` option to wait until the pipeline
completes.
If the pipeline is successful, then a merge of the staging branch into
the master branch should be the next step.

GCC supports "#pragma GCC diagnostic" since version 4.6, and
Clang seems to support it, too, since its early versions 3.x.
That means that our minimum required compiler versions all support
this pragma already and we can remove the test from configure and
all the related #ifdefs in the code.

Otherwise the result is basically unpredictable.
(Note that the precise environment variable to control sorting order is
LC_COLLATE, but LC_ALL overrides LC_COLLATE, and we do not want the
sorting order to be messed up if LC_ALL is set in the environment.)

This reverts commit 8d5a24c83d.
Compiling all virtio-gpu objects into a single module isn't a good plan
because the individual objects have different CONFIG_* dependencies.
Leads to module load failures on s390x due to vga support being
disabled, which in turn breaks '-device virtio-gpu-device' (flagged by
travis ci).
So back to the drawing board for modular virtio-gpu ...

I only spotted this in the small window between my testing with my
registry while waiting for the gitlab PR to go in. As we pre-pull the
registry image we know if that fails there isn't any point attempting
to use the cache. Fall back to the way we used to do it at that point.

In 06c4cc3660, we split the multiplication in two parts to avoid
a clang warning. But because double still rounds to 53 bits, this
does not provide additional precision beyond multiplication by
nextafter(0x1p64, 0), the largest representable value smaller
than 2**64.
However, since we have eliminated 1.0, mutiplying by 2**64 produces
a better distribution of input values to the output values.

Since the seed must be non-zero, subtracting 1 means puts the
rate in 0..UINT64_MAX-1, which allows the 0 and UINT64_MAX
thresholds to corrspond to 0% (never) and 100% (always).

s390x is our only big endian host in our CI, so building and testing QEMU
there is quite valuable. Thus let's also test the other targets with
additional jobs (also using different sets of pre-installed libraries to
get a better coverage of the things that we test).

Instead of building the docker files directly use the same docker.py
scripting as we do for building locally. This should help ensure we
use the exact same steps and allow us to cache properly when building
locally.
To get this working you have to have a fairly recent docker binary
otherwise you will see the error message:
=> ERROR importing cache manifest from registry.gitlab....

Total execution time with "-m slow" and x86_64 QEMU, drops from 3
minutes 15 seconds, down to 54 seconds.
Individual tests drop from 17-20 seconds, down to 3-4 seconds.
The cost of this change is that any QOM bugs resulting in the test
failure will not be directly associated with the device that caused
the failure. The test case is not frequently identifying such bugs
though, and the cause is likely easily visible in the patch series
that causes the failure. So overall the shorter running time is
considered the more important factor.
