i965: extend fast texture upload

Extend the fast texture upload from BGRA X-tiled to include RGBA,
Alpha/Luminance, and Y-tiled.  Speed improvements, measured with
mesa demos teximage program, on 256 x 256 texture, in MB/s, on a
Sandy Bridge (Ivy is comparable):

              before  after   increase
BGRA/X-tiled   3266    4524    1.39x
BGRA/Y-tiled   1739    3971    2.28x
RGBA/X-tiled    474    4694    9.90x
RGBA/Y-tiled    477    3368    7.06x
   L/X-tiled   1268    1516    1.20x
   L/Y-tiled   1439    1581    1.10x

v2: Cosmetic changes only: reformat and reword comments, make doxygen-friendly,
    rename variables, use existing macros, add an assert.

mesa: Allow external textures to use fallback (0, 0, 0, 1)

Fixes GL2ExtensionTests/egl_image_external/TestSimpleUnassociated.test
which is part of gles2/3 conformance suite. Here image external
textures are switched to be treated the same as 2D textures. These
can be associated with the fallback texture providing fixed sample
values of (0, 0, 0, 1).

The OES_EGL_image_external spec says:

  "Sampling an external texture which is not associated with any EGLImage
   sibling will return a sample value of (0,0,0,1)."

  "External textures cannot be used with TexImage2D, TexSubImage2D,
   CompressedTexImage2D, CompressedTexSubImage2D, CopyTexImage2D, or
   CopyTexSubImage2D, and an INVALID_ENUM error will be generated if
   this is attempted."

And quoting Chad:

  "That's enforced in _mesa_TexImage*() by calling
   legal_teximage_target(), and enforced in _mesa_TexSubImage*() by
   calling legal_texsubmimage_target(). Each of the
   legal_tex*image_target() functions reject external textures.
   Therefore, allowing GL_TEXTURE_EXTERNAL_OES in store_texsubimage()
   won't violate the above spec quote.

   I think it's safe to allow GL_TEXTURE_EXTERNAL_OES in
   store_texsubimage(), as long as the texture has only a single
   plane. Luckily, that's the only type of external textures that
   Mesa currently supports."

r600g: fix crash in set_framebuffer_state

We should be able to safely set the framebuffer state without a
fragment shader bound. bind_ps_state will take care of updating the
necessary state bits later.

v2: check in update_db_shader_control
glsl: Remove extraneous .dir-locals.el

This was overriding the top-level .dir-locals.el causing some settings
(like forcing spaces instead of tabs!) to be lost.

wayland: Don't rely on static variable for identifying wl_drm buffers

Now that libEGL has been fixed to not leak all kinds of symbols, gbm
links to its own copy of the libwayland-drm.a helper library.  That means
we can't rely on comparing the addresses of a static vtable symbol in that
library to determine if a wl_buffer is a wl_drm_buffer.  Instead, we
move the vtable into the wl_drm struct and use that for comparing.
