These constants aren't available from the system headers so don't expose
them here.

Add const socket protocol for divert rule ipfw on FreeBSD

Link libc crate against pthread

pthread_* functions are defined in libpthread thus we need to link against
this library.

Make networking on Solaris/Illumos great again

Add fchown

add UTIME_OMIT, UTIME_NOW on linux

add truncate64/readdir64/openat64 on linux

add AT_* constants

Add FIONREAD for apple/b64

Adds the FIONREAD constant for macos/x86_64 machines.

add fdopendir

Solaris/Illumos: Add several more filio ioctls

MIO needs these

move *at family to unix

apparently supported on all platforms.

Get CI working again

Add support for the `accept4` system call for FreeBSD* & NetBSD*

As outlined in #540.

However since support for this system call seems to be committed, but not yet released in NetBSD & BitRig (is BitRig actually still be developed at all, btw?), I'm not sure whether it wouldn't be a better idea to only add OpenBSD support instead?
What's the official policy on this?

Bump to 0.2.21

Adds many socket related constants

Started off adding a few constants to help cleaning up some `nix-rust/nix` issues.  Went a little.. further.

Adds lots of socket-related constants (`PF_*`, `MSG_*`, `AF_*`, `SO_*`, `SOL_*`, etc.) to linux/bsd flavors.

Added constants to `bsd/frebsdlike/dragonfly` for completeness, though they aren't covered by CI.  Did not touch `notbsd/linux/s390x.rs`
