Brian Paul 2102e301a7 glsl: fix a bug involving 'continue' in 'for' loops 
Need to execute the for loop's increment code before we continue.
Add a slang_assemble_ctx::CurLoopOper field to keep track of the containing
loop and avoid the "cont if true" path in this situation.

Plus, assorted clean-ups.

Brian Paul 625b0fe268 Revert "slang: if/else/break & if/else/continue work for unrolled loops" 
We should just check if the loop contains a continue/break in the
_slang_can_unroll_for_loop() test function...

This reverts commit 989856bde4.

Brian Paul 4031ea1520 glsl: Added gl_shader_state::EmitContReturn field 
This is the start of a glsl-continue-return feature branch to support
a GLSL code generator option for 'continue' and 'return' statements.
Some targets don't support CONT or RET statements so we'll need to
try to generate code that does not use them...

Keith Whitwell 3e94521912 tgsi: correct handling of return value from util_vsnprintf 
We were failing to deal with:
  - vsnprintf returns negative value on error.
  - vsnprintf returns the number of chars that *would* have been
    written on truncation.

Brian Paul b79e6a59d8 demos: fix issues in glxcontexts.c 
The reshape() function was called when there was no GLX context so
the viewport/modelview/projection setup wasn't doing anything.  Move
the call to reshape() into draw().

Also, remove -stereo, -fullscreen options and do some general clean-up.

Roland Scheidegger 2f184d0d9f i965: handle OPCODE_SWZ in the glsl path 
glsl compiler will not generate OPCODE_SWZ, and as a first step it would
be translated away to a MOV anyway (why?), but later internally this opcode is
generated (for EXT_texture_swizzling).

Owen W. Taylor 9d367d43b2 Disable SGI_swap_control extension for DRI2 
We currently don't have support for SGI_swap_control for direct
contexts with DRI2, so disable reporting the extension. Reporting
the extension, and then having glXSwapIntervalSGI() "succeed"
but do nothing can confuse applications.

Brian Paul 54f425b5ce mesa: rename MAX_VERTEX_ATTRIBS to MAX_VERTEX_GENERIC_ATTRIBS

attributes, not counting the legacy attributes (pos, normal, color, etc).
