llvmpipe: support GL_ARB_texture_buffer_object/GL_ARB_texture_buffer_range

This also fixes not honoring first/last_layer view parameters for array
textures, plus not honoring last_level view parameter for all textures
(neither is really used by OpenGL).
This mostly passes piglit arb_texture_buffer_object tests (it needs, however,
glsl 140 version override, plus GL 3.1 override, the latter only because
mesa does not allow ARB_tbo in non-core contexts).
Most arb_texture_buffer_object tests pass, with the exception of
arb_texture_buffer_object-formats. With "arb" parameter it passes most weirdo
formats before it segfaults in the state tracker, this looks to be some issue
with using legacy formats in core context (fails the same in softpipe).
With "core" parameter it passes with "fs", however fails with "vs" (for most
formats). This will be fixed later (debugging shows we're completely missing
the shader recompile depending on format).

v2: based on Jose's feedback, fix comments, variable/function names.
