f08bebfe24 mesa: raise MAX_VARYING (number of shader varying vars) to 16 
16 is the limit for now because of various 32-bit bitfields.

2d86503471 intel / DRI2: Additional flush of fake front-buffer to real front-buffer 
To maintain correctness, the server will copy the real front-buffer to
a newly allocated fake front-buffer in DRI2GetBuffersWithFormat.
However, if the DRI2GetBuffersWithFormat is triggered by glViewport,
this will copy stale data into the new buffer.  Fix this by flushing
the current fake front-buffer to the real front-buffer in
intel_viewport.

Fixes bug #22288.

8e6dd8bf79 glsl: overhaul 'return' statement handling 
A new node type (SLANG_OPER_RETURN_INLINED) is used to denote 'return'
statements inside inlined functions which need special handling.

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.

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.

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...

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.

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).

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.
