Add more WASI libc definitions. 

This adds various WASI libc definitions to the Rust libc bindings that I
needed while porting some applications to WASI.

It also removes the `pause` binding since newer versions of WASI libc
have removed this function as well. (WASI currently has no syscall with
this functionality.)
