nv50,nvc0: never convert in resource copy when format sizes match
If there are any cases left where the st thinks that RGBA -> BGRA
will swap components, it will get what it deserves.
Now the GPU's 2D engine goes unused. What a shame.
mesa: In validate_program(), initialize errMsg for safety.
validate_program relies on validate_shader_program to fill in errMsg;
empirically, there exist cases where that doesn't happen.
While tracking those down may be worthwhile, initializing the string so
we don't try to ralloc_strdup random garbage also seems wise.
Fixes issues caught by valgrind while running some test case.
NOTE: This is a candidate for stable release branches.

glx/dri2: Paper over errors in DRI2Connect when indirect
DRI2 will throw BadRequest for this when the client is not local, but
DRI2 is an implementation detail and not something callers should have
to know about. Silently swallow errors in this case, and just propagate
the failure through DRI2Connect's return code.
Note: This is a candidate for the stable release branches.

This saves both register space and upload bandwidth for unused values.
Note that previously we were relying on the visitor not initially
generating references to different sets of uniforms between the 8-wide
and 16-wide code generation, and now we're relying on them dead-code
eliminating the same stuff, too.
We should remove the relocations which caused a validation failure
from the list, so that the kernel receives only the validated ones.

vbo: do not call _mesa_max_buffer_index in debug builds
That code drops performance in Unigine Heaven and Tropics
by a factor of 10. That's too crazy even for a debug build.
NOTE: This is a candidate for the 7.11 branch.

Unlike C++, empty declarations such as
float;
should be valid. The spec is not explicit about this actually.
Some apps that generate their shader sources may rely on this. This was
noted when porting one of them to Linux from Windows.

gallium: extend resource_resolve to accommodate BlitFramebuffer
Resolve via glBlitFramebuffer allows resolving a sub-region of a
renderbuffer to a different location in any mipmap level of some
other texture, and, with a new extension, even scaling. Therefore,
location and size parameters are needed.
The mask parameter was added because resolving only depth or only
stencil of a combined buffer is possible as well.
Full information about the blit operation allows the drivers to
take the most efficient path they possibly can.
