intel: gen-decoder: rework how we handle groups

The current way of handling groups doesn't seem to be able to handle
MI_LOAD_REGISTER_* with more than one register. This change reworks
the way we handle groups by building a traversal list on loading the
GENXML files.

Let's say you have

Instruction {
  Field0
  Field1
  Field2
  Group0 (count=2) {
    Field0-0
    Field0-1
  }
  Group1 (count=4) {
    Field1-0
    Field1-1
  }
}

We build of linked on load that goes :

Instruction -> Group0 -> Group1

All of those are gen_group structures, making the traversal trivial.
We just need to iterate groups for the right number of timers (count
field in genxml).

The more fancy case is when you have only a single group of unknown
size (count=0). In that case we keep on reading that group for as long
as we're within the DWordLength of that instruction.

This new field helps simplify l3 way size computations
in next patch.

V2: Initialize the l3_banks to 0 in macros.

i965: Replace 0 with ISL_FORMAT_UNSUPPORTED in format table (v2)

When given an *unsupported* mesa_format,
brw_isl_format_for_mesa_format() returned 0, a *valid* isl_format,
ISL_FORMAT_R32G32B32A32_FLOAT.  The problem is that
brw_isl_format_for_mesa_format's inner table used 0 instead of
ISL_FORMAT_UNSUPPORTED to indicate unsupported mesa formats.

Some callers of brw_isl_format_for_mesa_format() were aware of this
weirdness, and worked around it. This patch removes those workarounds.

v2: Ensure that all array elements are initialized to
  ISL_FORMAT_UNSUPPORTED, even when new formats are added to enum
  mesa_format, by using an designated range initializer.

st/dri: move fence implemention into separate file

Since the fence implementation is not dri2.c specific, put
it in a separate file. This way SW implementations can use this
extension too.

v2: Don't depend on dri2.c for extensions (Emil)

xlib: fix glXGetCurrentDisplay() failure

glXGetCurrentDisplay() has been broken for years and nobody noticed until
recently.  This change adds a new XMesaGetCurrentDisplay() that the GLX
emulation API can call, just as we did for glXGetCurrentContext().

Tested by hacking glxgears to call glXGetCurrentContext() before and
after glXMakeCurrent() to verify the return value is NULL beforehand and
the same as the opened display afterward.

Also tested by Tom Hudson with his tests programs.

This changes behaviour, but aligns with what radeonsi does,
it does double emits on CIK/VI, whereas previously it only
did this on CIK.

intel/isl: Add a helper for getting the byte/tile offset of a subimage

Frequently, get_image_offset_sa is combined with get_intratile_offset_sa
so it makes sense to have a single helper to do both.  If the caller
doesn't want the intratile offsets, it can simply pass NULL and ISL will
assert that they are 0.
