intel: Require the right amount of space in glBitmap blit acceleration.
This leads to problems when the batchbuffer is flushed, but the bitmap
data could not fit into it.

mesa: Fix GenerateMipmapEXT(GL_TEXTURE_CUBE_MAP_ARB).
The ctx->Driver.GenerateMipmap() hook only expects cubemap face enums, not
CUBE_MAP_ARB, so walk all faces when we encounter that. Fixes oglconform
fbo.c segfault with both swrast and i965 drivers.

commit 75b26e18a64b2fb1962e5e49dfaebd257c734ecc

intel: Fix crash in automatic mipmap generation for glCopyTex{Sub,}Image.
The images aren't mapped at this point, so we want the generic Mesa path for
GenerateMipmapEXT that does the mapping/unmapping for us. Ideally Mesa
would
just call it for us.
