rust: uapi: Add UAPI crate
This crate mirrors the `bindings` crate, but will contain only UAPI
bindings. Unlike the bindings crate, drivers may directly use this crate
if they have to interface with userspace.
Initially, just bind the generic ioctl stuff.
In the future, we would also like to add additional checks to ensure
that all types exposed by this crate satisfy UAPI-safety guarantees
(that is, they are safely castable to/from a "bag of bits").
[ Miguel: added support for the `rustdoc` and `rusttest` targets,
since otherwise they fail, and we want to keep them working. ]
