Xiang, Haihao 09623fe551 intel: reset cliprect_mode to IGNORE_CLIPRECTS. 
This ensures all batchbuffers have a same cliprect mode after calling
_intel_batchbuffer_flush even if there aren't invalid commands in the
current batch buffer. (fix bug#18362).

Xiang, Haihao 8412b06b67 mesa: restore the negate flag of dots in build_lighting. 
Dots is re-used if more than one light is enabled. Previously
the negate flag of dots may affect next light.

Brian Paul 59cc973940 mesa: fix some misc breakage caused by editing auto-generated files rather than the python generators 
Specifically:
  #include "glapitable.h" in src/mesa/main/glapi/dispatch.h
  Call _mesa_bsearch() in src/mesa/main/enums.c.

Brian Paul 13f96c5401 GLX: fix out-of-bounds memory issue in indirect glAreTexturesResident() 
See bug 18445.
When getting array results, __glXReadReply() always reads a multiple of
four bytes.  This can cause writing to invalid memory when 'n' is not a
multiple of four.

Special-case the glAreTexturesResident() functions now.
To fix the bug, we use a temporary buffer that's a multiple of four bytes
in length.

NOTE: this commit also reverts part of commit 919ec22ecf
(glx/x11: Added some #ifdef GLX_DIRECT_RENDERING protection) which
directly edited the indirect.c file rather than the python generator!
I'm not repairing that issue at this time.

Brian Paul f6ead50827 mesa: added OPCODE_NRM3/NRM4 instructions for vector normalization. 
We may emit these instructions from GLSL instead of DP3/RCP/MUL.

Also, implement SSG (set sign) instruction in the interpreter.

Brian Paul 517401af07 mesa: update the shader programs->TexturesUsed array at link time 
If an application never calls glUniform() to set sampler variable values
they'll remain 0 (the default value/unit).
Now call _mesa_update_shader_textures_used() at link time in case glUniform()
is never called.  program->TextureUsed[] will then be correct for state
validation.

Xiang, Haihao df94fd1764 i965: Always check vertex program. 
Now i965 also uses the vertex program created by Mesa Core, but this vertex program
is not only depend on mesa state _NEW_PROGRAM, so always check the current vertex
program is updated or not. This fixes broken demo cubemap.

Keith Packard 72c914805b Fix for 58dc8b7: dest regions must not use HorzStride 0 in ExecSize 1 
Quoting section 11.3.10, paragraph 10.2 of the 965PRM:

10.2. 	If ExecSize is 1, dst.HorzStride must not be 0. Note that this is
	relaxed from rule 10.1.2. Also note that this rule for destination
	horizontal stride is different from that for source as stated in
	rule #7.

GM45 gets very angry when rule 10.2 is violated.

Patch 58dc8b7 (i965: support destination horiz strides in align1 access mode)
added support for additional horizontal strides in the ExecSize 1 case, but
failed to notice that mesa occasionally re-purposes a register as a
temporary destination, even though it was constructed as a repeating source
with HorzStride = 0.

While, ideally, we should probably fix the code using these register
specifications, this patch simply rewrites them to use HorzStride 1 as the
pre-58dc8b7 code did.
