Add std::process::abort
This calls libc abort on Unix and fastfail on Windows, first running
cleanups to do things like flush stdout buffers. This matches with libc
abort's behavior, which flushes open files.

std: Derive `Default` for `Duration`.
Discussed in #37546 the libs team reached the conclusion that a default zero
duration seems like a reasonable implementation of the `Default` trait.
Closes#37546
Remove one bounds check from BufReader
Very minor thing. Otherwise the optimizer can't be sure that pos <= cap. Added a paranoid debug_assert to ensure correctness instead.

Stabilize `..` in tuple (struct) patterns
I'd like to nominate `..` in tuple and tuple struct patterns for stabilization.
This feature is a relatively small extension to existing stable functionality and doesn't have known blockers.
The feature first appeared in Rust 1.10 6 months ago.
An example of use: https://github.com/rust-lang/rust/pull/36203
Closes https://github.com/rust-lang/rust/issues/33627

std: Track change to cprng syscall signature (Fuchsia)
The mx_cprng_draw syscall has changed signature to separate the status
and size return values, rather than multiplexing them into a single
value with errors interpreted as a negative value. This patch tracks
that change.

Add conversions from `io:ErrorKind` to `io::Error`
Filing to help with discussion around the possibility of doing this.
Current changes are clearly backwards incompatible, but I think adding a new function (with a bikeshed on naming) like `Error::new_str` should be possible (or some other way of specializing the string error message case) to fix#36658.
More refactoring to obey platform abstraction lint
The most interesting things here are moving `std/sys/common` to `std/sys_common`, and `std/num/{f32,f64}.rs` to `std/{f32,f64}.rs`, and adding more documentation to `std/lib.rs`.
