i965: Set "Subslice Hashing Mode" to 16x16 on Apollolake.

As of 4.11, the kernel isn't bothering to set the subslice hashing mode
on Apollolake, leaving it at the default of 8x8.  (It initializes it to
16x4 on most platforms.)

Performance data for GPUTest Triangle on Apollolake at 1024x640:

   X-tiled RT:
   -----------
   8x8 -> 16x4:   2.4325%  +/- 0.383683% (n=107)
   8x8 -> 8x4:   -3.75105% +/- 0.592491% (n=40)
   8x8 -> 16x16:  6.17238% +/- 0.67157%  (n=30)

   Y-tiled RT:
   -----------
   8x8 -> 16x4:   1.30307%  +/- 0.297292% (n=205)
   8x8 -> 8x4:   -0.769282% +/- 0.729557% (n=35)
   8x8 -> 16x16:  3.00254%  +/- 0.715503% (n=40)

   8x MSAA RT (INTEL_FORCE_MSAA=8):
   --------------------------------
   8x8 -> 16x4:   1.38889% +/- 0.93729%  (n=7)
   8x8 -> 8x4:   -2.10643% +/- 1.15153%  (n=3)
   8x8 -> 16x16:  3.87183% +/- 1.08851%  (n=5)

Based on this, we choose 16x16 for Apollolake.

Skylake GT2 with X-tiled buffers appears to be a toss-up between 16x4
and 16x16, and with Y-tiled buffers it doesn't seem to really matter.
So we'll leave Skylake alone for now.

The hashing mode doesn't seem to make a measurable impact on more
complex benchmarks.

mesa/st: Reduce the number of frontbuffer flush calls

The mesa state tracker was needlessly flushing the front buffer even if it
hadn't been drawn to since the last flush. This was happening during
glXSwapBuffers if we at some point previously had set that frontbuffer as
a read- or draw renderbuffer, or at glFlush() or glFinish() if we at some
point previously had rendered to the front buffer. Since the frontbuffer
flush typically means a full drawable copy, it's a pretty big waste.

We will switch to the pipe_loader loading the configuration options,
so that they can be passed to the driver independently of the state
tracker.

Put the description into its own file so that it can be merged easily

glx: use v2 of DRI_ConfigOptions

Most of the change is concerned with avoiding memory leaks, since v2 of

resolve the long-standing issue of keeping drivers loaded when returning
from glXGetDriverConfig.

dri: define a version 2 of the DRI_ConfigOptions extension

The new function is defined to return a malloc'ed pointer. In the
following patches, this helps avoid leaking library handles when pipe
drivers are linked dynamically.

It also allows us to generate the XML string on the fly in the future.
