Regularize our handling of <sys/signal.h>: currently we include it in
osdep.h, but only for OpenBSD, and we include it without an ifdef
guard in a couple of C files. This causes problems for Haiku, which
doesn't have that header.
Instead, check in configure whether sys/signal.h exists, and if it
does then always include it from osdep.h.

If the pipeline is successful, then a merge of the staging branch into

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).
