The mesa state tracker is currently the only place where we create a
context and expect it to implement GLES1/2. Use the API-aware constructor
to communicate this to core mesa.
This introduces a new way to create or initialize a context:
_mesa_create_context_for_api and
_mesa_initialize_context_for_api
which in addition to the current arguments take an api enum to indicate
which OpenGL API the context should implement. At this point the
API field in GLcontext isn't used anywhere, but later commits will
key certain functionality off of it.
The _mesa_create_context and _mesa_initialize_context functions are
kept in place as wrappers around the *_for_api versions, passing in
API_OPENGL to get the same behavior as before.
As in tgsi_exec.c we don't actually rely on condition codes; we do
an unconditional kill. The only predication comes from the execution
mask which applies inside loops/conditionals.
New draw API function to indicate whether or not to convert points to
quads for sprite rasterization.
Fix point-to-quad conversion regression in the wide-point stage. We
need to check the pipe_rasterizer_state::point_quad_rasterization flag.
Rename old IGDNG to Ironlake, and set 'gen' number for
Ironlake as 5, so tracking the features with generation num
instead of special is_ironlake flag.

Previously, when we created a gallium texture for a corresponding Mesa
texture we'd only allocate space for mipmap levels >= BaseLevel.
This patch undoes that mechanism. This fixes a render-to-texture bug
when rendering to level 0 when BaseLevel=1.
Also, it makes sense to allocate the whole texture object memory when
BaseLevel > 0 since a common use of GL_TEXTURE_BASE_LEVEL is to
progressively load/render mipmaps. Eventually, the app almost always
fills in the level=0 mipmap image.
Finally, the texture image code is bit easier to understand now.
