563fb8e43d Implement dup and close for stdin/stdout/stderr
Support F_DUPFD on stdin/stdout/stderr

Enable `close`-ing stdin/stdout/stderr

For `dup`, check if FD is `File` first

If not, clone the appropriate standard IO stream

Merge POSIX `close` and `dup` tests into same module

Also, add assertion that `write` on a closed FD returns an error.

Add `dup` as FileDescriptor trait fn

Also:
- Fix `close` so it drops `self` instead of reference to it
- Remove FD clamping in insert_fd_with_min_fd, since FDs 0-2 can be
closed

Fix fs_libc tests

Make error message when closing stdin/out/err more specific

Return io::Result from `FileDescriptor::dup`

Change error message when closing stdin/out/err

Refactor `FileDescriptor::dup` impl for `FileHandle`

Remove empty line

Nanosleep

This PR adds a shim for `libc::nanosleep`, (available under -Zmiri-disable-isolation only) which backs `thread::sleep` on Linux and macOS. I started off by extracting the `timespec` parsing from the `pthread_cond_timedwait` shim into a helper method, and adding checks for invalid values. The second commit adds the new shim and a small test. The shim blocks the current thread, and registers a timeout callback to unblock the thread again, using the same method as `pthread_cond_timedwait` does.

Move panic payload state from Machine to Thread

This PR moves the panic payload storage from the `Machine` state to per-thread state. Prior to this change, if one thread panicked while another was still unwinding, Miri would fail with `thread 'rustc' panicked at 'the panic runtime should avoid double-panics', src/shims/panic.rs:51:9`. I ran into this issue while prototyping a round-robin scheduler, but it's also reachable with the current scheduler and contrived programs that use blocking API calls to cause thread switching during unwinding. I wrote a test case along those lines for this change.
