mesa: Restore depth texture state on glPopAttrib(GL_TEXTURE_BIT).
According to Table 6.17 in the GL 2.1 specification, DEPTH_TEXTURE_MODE,
TEXTURE_COMPARE_MODE, and TEXTURE_COMPARE_FUNC need to be restored on
glPopAttrib(GL_TEXTURE_BIT).
Makes a number of oglconform tests happier.
v2: Make restoration conditional on the ARB_shadow and ARB_depth_texture
extensions, as suggested by Brian. I'm not sure that any
implementations still remain that don't support those, but why not?
NOTE: This is a candidate for stable release branches.
