Merge 'Performance improvements for Unix I/O backend' from Preston Thorpe
...
This PR reworks the unix I/O backend, removing runtime reference
counting/borrow checking and optimizing away the hashmap in favor of a
static array, with an unlikely fallback vec.
The only reason the fallback vec is there is because unlike the
`io_uring` module, we cannot simply index into the array with the fd as
the OS could theoretically give us a fd up to I believe 1024 so keeping
an array of that size for a few elements is unnecessary.
Closes #940

core: remove dependency on nix. We keep depending on libc, though, because crate io_uring requires libc's iovec.
