There's nothing inherently fixed-width in the code.  All that's required

anv: Use separate MOCS settings for external BOs

On Broadwell and above, we have to use different MOCS settings to allow
the kernel to take over and disable caching when needed for external
buffers.  On Broadwell, this is especially important because the kernel
can't disable eLLC so we have to do it in userspace.  We very badly
don't want to do that on everything so we need separate MOCS for
external and internal BOs.

In order to do this, we add an anv-specific BO flag for "external" and
use that to distinguish between buffers which may be shared with other
processes and/or display and those which are entirely internal.  That,
together with an anv_mocs_for_bo helper lets us choose the right MOCS
settings for each BO use.

Revert "mesa: remove unnecessary 'sort by year' for the GL extensions"

This reverts commit 3d81e11b49366b5636b8524ba0f8c7076e3fdf34.

As reported by Federico, some games require the 'sort by year' since
they truncate the extensions which do not fit the fixed size string
array.

Seemingly I did not consider that, as the documentation (both Mesa and
Nvidia) mentions about program crashes ... which are worked around by
setting the env. variable.

This commit reinstates the workaround and enhances the documentation.
