nouveau > 10 years ago had a plan for new multiplexer inside a multiplexer
API using nvif. It never fully reached fruition, fast forward 10 years,
and the new vulkan driver is avoiding libdrm and calling ioctls, and
these 3 ioctls, getparam, channel alloc + free don't seem to be things
we'd want to use nvif for.

Undeprecate and put them into the uapi header so we can just copy it
into mesa later.

Do we want to use `uint32_t` or `__u32` here? It looks like the original
headers used `uint32_t` and then it got switched to `__u32` after the
deprecation happened.  We probably want `__u32` given that this is a uapi
header.

IDK what to do about this one. I want to make it __s32. I think that should
be safe on all the hardware we care about. Having an unsized type in a UAPI
header is concerning.

Do we have any architectures we care about where `int` isn't `__s32`? I
think on all 32/64 bit x86, ppc and arm it's that way and I don't think we
care about anything else?
