Where structures included unions, I only defined the most useful member.  This
means that sigevents can't be delivered using SIGEV_THREAD until Rust gets better
union support (SIGEV_THREAD_ID still works).

Use `#[link(cfg(..))]` in preparation for libstd

In preparation for rust-lang/rust#37545 this is adding the appropriate
directives to libc to get included.

Minimal liblibc for Redox

add pledge(2) syscall.

Remove mipsel target_arches

The `mipsel` `target_arch` was introduced with the initial MIPSel
support (rust-lang/rust@82ec1aef293ddc5c6373bd7f5ec323fafbdf7901),
but was subsequently removed with implementation of the Flexible Target
Specification (Rust RFC 0131,
rust-lang/rust@3a8f4ec32a80d372db2d02c76acba0276c4effd0).
Remove these to be consistent with other arches and reduce confusion.

I've very slightly formatted the deletions so as to not require a style
cleanup later and obscure `git blame` output.

Update CI download location

Add setfsgid()/setfsuid() on linux

Fix typo in comment

Generate docs on 1.10.0

Should help us keep the size explosion under control.

Added tcsetpgrp

Enable musl with aarch64

Add setresuid/setresgid for linux

Signed-off-by: Dylan Reid <dgreid@chromium.org>

Add support for Fuchsia

Try to fix powerpc64 and update to crates.io ctest

This reverts commit 7ac91c6d.

Merge two separate config blocks for conditionally including ai_addr
in the addrinfo struct for unix/notbsd.

The reference to the unwind lib belongs in libstd, not here. Also fix
lint error.

These patches add support for the Fuchsia operating system. For the
time being, it shares a lot of infrastructure with the Linux target,
because of the use of a musl-based libc.

Add UNIX 98 pty functions

Bump to 0.2.17

Add SO_REUSEPORT to mips64
