- The previous solution was hacky and didn't do subchannel autobinding.
- The beheaviour should match what libdrm_nouveau does closely.
- The solution remains statically sized, but when debugging is on it will check
for abuse.

several drivers which chose to ignore edgeflags might require some more work,
while edgeflags never worked there they might now crash.

Rename Semantic.SemanticName to Semantic.Name. Similar for
SemanticIndex, and the members of the tgsi_version struct.

It would be nice if these drivers built under the linux-debug header
so that these types of interface changes can be minimally propogated
into those drivers by people without the hardware. They don't have to
generate a working driver -- though a command-dumping winsys would be
an excellent for regression checking.

|
Likewise, the extended negate functionality hasn't been
used since mesa switched to using tgsi_ureg to build programs,
and has been translating the SWZ opcode internally to a single MAD.
|
|
These haven't been used by the mesa state tracker since the
conversion to tgsi_ureg, and it seems that none of the
other state trackers are using it either.
This helps simplify one of the biggest suprises when starting off with
TGSI shaders.

Remove the need to have a pointer in this struct by just including
the immediate data inline. Having a pointer in the struct introduces
complications like needing to alloc/free the data pointed to, uncertainty
about who owns the data, etc. There doesn't seem to be a need for it,
and it is unlikely to make much difference plus or minus to performance.
Added some asserts as we now will trip up on immediates with more
than four elements. There were actually already quite a few such asserts,
but the >4 case could be used in the future to specify indexable immediate
ranges, such as lookup tables.

libdrm_nouveau is linked with the winsys, there's no good reason to do all
this through yet another layer.

Gallium used to do this for us :)

It turns out the user planes handed to the driver are already in clip space.
Hence, we no longer need to transform incoming vertices before computing the
clip distance, and no longer need to change the interface provided by
gallium. Yay :)
The clip state change handling could be better, but this works.
