This function has been added in glibc 2.25, and the related syscall in
Linux 3.17, in order to avoid requiring the /dev/urandom to exist, and
doing the open()/read()/close() dance on it.
We pass GRND_NONBLOCK so that it doesn’t block if not enough entropy has
been gathered to initialise the /dev/urandom source, and fallback to the
next source in any error case.

The vma_heap allocator was originally designed to prefer high addresses
in order to find bugs in ANV's high address handling. However, there
are cases where you might want the allocator to prefer lower addresses
for some reason. This provides a configure bit for exactly this
purpose.

When the LLVM version is too old or missing, SotTR applies shader
workarounds and that reduces performance by 2-5% with ACO.
SotTR workarounds are applied with LLVM 8 and older, so reporting
LLVM 9.0.1 should be fine.

SCHED_IDLE on linux can lead to extraordinarily long periods of no scheduling
leading to starvation of minimum priority threads for such an extended period
that it can eventually lead to GUI stalls. Switch to renicing the threads to
the lowest priority and use the SCHED_BATCH scheduling policy which is a hint
to the scheduler that this is latency insensitive thread instead. This change
has been confirmed to address unexpected GUI related stalls in mesa
applications across a range of different linux kernels.

This is currently broken hard, because this code is being used in more
places that it used to be, and fixing that is prohibitively hard right
now.
This is far from ideal, as it leaves the same inconsistency in the
EMBEDDED_DEVICE code-path. But that only used by VMWare, so it's
probably better if they fix it, as they know their requirements better
than we do.

This adds two new util functions to rounding.h, _mesa_iroundf and
mesa_lround, which are just wrappers around roundf and round, that cast
to int and long int respectively. This is possible since mesa recently
dropped support for VC2013, since 2015 and 2017 support roundf.
