When points or lines are decomposed into triangles, we need to be sure
to disable polygon culling, stippling, "un-filled" modes, etc.
This patch sets the rasterization state to disable those things prior to
drawing points/lines with triangles, then restores the previous state
afterward.
The new piglit point-no-line-cull test checks this problem & solution.
Fixes crash when using _mesa_CopyTexImage2D.

In the direct rendered case, we need to convert DRI2 swap complete
events to GLX events for the client to consume. This path had what
looks like a stray "& 0x75" from some earlier debugging that prevented
clients from seeing the right event code.
When matching attributes using the 'mask' matching criteria, the spec
says that
"Only GLXFBConfigs for which the set bits of attribute include all
the bits that are set in the requested value are
considered. (Additional bits might be set in the attribute)."
The current test returns true if the two bit masks have bits in
common, specifically it matches even if the requested value has bits
set that are not set in the fbconfig attribute. For example, an
application asking for
GLX_DRAWABLE_TYPE, GLX_PIXMAP_BIT | GLX_PBUFFER_BIT,
as glxpbdemo does, will match fbconfigs that don't support pbuffer
rendering, as long as they support pixmap rendering.

Commit 1454f20a99 caused the regression.
When the vertex shader emitted both a texcoord and color we were grabbing
the wrong vertex attributes. Fix the draw_quad() code to put texcoords
in slot[1] and color in slot[2]. That's a bit cleaner than changing
the vertex shader code.
Tested with progs/tests/zreaddraw.c
piglit has a test called fbo-drawbuffers, this fails for me on r300g,
and fixing the texenv program to use the DATA outputs fixes it.

Need to check pipe_blend_state::independent_blend_enable to determine
which render target/index to use when checking blend enable and colormask
state.
This is part of the fix for piglit/fbo-drawbuffers
The IDs will be the same in the case where an X window is used directly
as a GLX drawable, but will fail if a new GLX drawable is created
explicitly, as with glxgears_fbconfig.
Fixes fdo bug #27190.
