library: Normalize safety-for-unsafe-block comments
...
Almost all safety comments are of the form `// SAFETY:`,
so normalize the rest and fix a few of them that should
have been a `/// # Safety` section instead.
Furthermore, make `tidy` only allow the uppercase form. While
currently `tidy` only checks `core`, it is a good idea to prevent
`core` from drifting to non-uppercase comments, so that later
we can start checking `alloc` etc. too.

reduce syscalls by inferring FD types based on source struct instead of calling stat()

`impl Write for &mut T where T: Write`, thus the same should
apply to the specialization traits

prioritize sendfile over splice since it results in fewer context switches when sending to pipes
...
splice returns to userspace when the pipe is full, sendfile
just blocks until it's done, this can achieve much higher throughput

specialize io::copy to use copy_file_range, splice or sendfile
...
Currently it only applies to linux systems. It can be extended to make use
of similar syscalls on other unix systems.
