even with the helpers there was still a bit of duplicated code between
platforms, with the drm authentication being the only part that
differs.

This patch changes the bufmgr interface to provide a self contained
object with a create function that takes a drm authentication callback
as an argument. That way all the helper functions are made static and
the "_helper" suffix was removed from the sources file name.

This change also removes the mix of Wayland client and server code in

are now contained in native_wayland_drm_bufmgr.c.

gen7 fbo: make unmatched depth/stencil configs return unsupported

For gen >= 7, we will use the lod/minimum-array-element fields to
support layered rendering. This means that we must restrict
the depth & stencil attachments to match in various more retrictive
ways. (Now the width, height, depth, LOD and layer must match)

The reason width, height, and depth must match is that the hardware
has a single set of width, height, and depth settings (in
3DSTATE_DEPTH_BUFFER) that affect both the depth and stencil buffers.
Since these controls determine the miptree layout, they need to be
set correctly in order for lod and minimum-array-element to work
properly.  So the only way rendering can work is if the width,
height, and depth match.

In the future, if this restriction proves to be a problem (say
because some crucial client application relies on rendering to
different levels/layers of stencil and depth buffers), then we can
always work around the restriction by copying depth and/or stencil
data to a temporary buffer prior to rendering (much in the same way
that brw_workaround_depthstencil_alignment() does today for
gen < 7), but hopefully that won't be necessary.

Section 4.3.8.1 (Input Layout Qualifiers) of the GLSL 1.50 spec
contains some tricky rules for how the sizes of geometry shader input
arrays are related to the input layout specification.  In essence,
those rules boil down to the following:

- If an input array declaration does not specify a size, and it
  follows an input layout declaration, it is sized according to the
  input layout.

- If an input layout declaration follows an input array declaration
  that didn't specify a size, the input array declaration is given a
  size at the time the input layout declaration appears.

- All input layout declarations and input array sizes must ultimately
  match.  Inconsistencies are reported as soon as they are detected,
  at compile time if the inconsistency is within one compilation unit,
  otherwise at link time.

- At least one compilation unit must contain an input layout
  declaration.
