linux: Don't emit a .note.ABI-tag section anymore (#26663)

We don't support pre-2.6 kernels anyway - the install docs say 2.6.28
for DRI - and apparently this confuses ld.so's sorting when multiple
libGLs are installed.  Just remove it.

Note: this is a candidate for the stable branches.

r600g/compute: Removed unused and untested code

There was a lot of code in evergreen_compute_internal.c that was not

i965/vs: Add a function to fix-up uniform arguments for 3-src insts.

Three-source instructions have a vertical stride overloaded to 4, which
prevents directly using vec4 uniforms as arguments. Instead we need to
insert a MOV instruction to do the replication for the three-source
instruction.

With this in place, we can use three-source instructions in the vertex
shader. While some thought needs to go into deciding whether its better
to use a three-source instruction rather than a sequence of equivalent
instructions (when one or more sources are uniforms or immediates), this
will allow us to skip a lot of ugly lowering code and use the BFE and
BFI2 instructions directly.

winsys/intel: new winsys for intel

This is a wrapper for libdrm_intel to allow the pipe driver to stay OS
agnostic.
ilo: new pipe driver for Intel GEN6+

This commit adds some boilerplate code.  The header files found under include/
are copied from i965.
ilo: add debug flags settable through ILO_DEBUG
ilo: hook up pipe_screen param and fence functions
ilo: hook up pipe screen format functions
ilo: hook up pipe screen resource functions
ilo: add command parser

The command parser manages batch buffers and command submissions.
ilo: hook up pipe context flush function
ilo: add functions to manage shaders

This commits add shader cache, shader state, shader variant, and etc.  It does
not add the shader compiler though.
