This resolves build warnings and failures for architectures where the
Linux userspace `asm/types.h` header defines 64-bit types (u64, s64) as
`long` instead of `long long`.
By defining `__SANE_USERSPACE_TYPES__`, these types are defined as
`long long` instead.

This moves the Rust sources out of rust_src/ and into the top level.
Running the bcachefs executable out of the development tree is now:
$ ./target/release/bcachefs command
or
$ cargo run --profile release -- command
instead of "./bcachefs command".
Building and installing is still:
$ make && make install

This would correspond to GFP_RECLAIM in the kernel - but we don't
distinguish between different types of reclaim here.
This solves a deadlock in the btree node memory allocation path - we
allocate with the btree node cache lock held but without GFP_KERNEL set.
