Currently restricted to non-Android Linux. In theory this should work on
Android as well (since it's a function of the kernel ABI), but the
released version of the NDK doesn't export it, so putting it in
`notbsd/mod.rs` makes Travis very unhappy.

Add support for Haiku x86 and x86_64

* Rework of original patches from Niels Sascha Reedijk
  that include style and build fixes for libc master

Use correct type for c_ulong and c_long on 32-bit netbsdlike

add CI for mips-musl

and fix the statvfs struct for this target

r? @alexcrichton

I didn't really test the CI part but this target now passes libc-test under QEMU

Add checksums to cargo lock files

add MSG_NOSIGNAL (linux, android)

see rust-lang/rust#36426

Add shadow password bindings

Add shadow password bindings: setspent, endspent, getspent, getspnam plus spwd, the corresponding struct.

[Example code](https://github.com/philippkeller/apue-rust/blob/master/src/bin/e06-01-shadow-pw.rs) (tested on Linux 4.4.0-21-generic)

Add getchar_unlocked and putchar_unlocked

Adds [getchar_unlocked](http://pubs.opengroup.org/onlinepubs/9699919799/functions/getchar_unlocked.html) and [putchar_unlocked](http://pubs.opengroup.org/onlinepubs/9699919799/functions/putchar_unlocked.html).

Add EAI_SYSTEM getaddrinfo error code.

This is useful to decide if value returned from getaddrinfo is actual
error or you should look at errno instead.

Add System V message queue bindings for Linux (glibc/musl)

Add netlink constants

Add netlink constants from linux/netlink.h

define `sethostname` under OpenBSD and Bitrig

factorize the definition with NetBSD

add time, localtime

time, localtime and strftime are all in POSIX.1 and should IMO all be part of `libc`.

I [tested the bindings](https://github.com/philippkeller/apue-rust/blob/master/src/bin/f06-11-strftime.rs) - works fine on OSX and linux.

And: I added the netbsd aliases based on `time.h` of netbsd

couldn't get strftime to work, even with help from IRC. Removing it now as it's not worth the hassle

Adding accept4 function

accept4 is a version of accept that takes flags.
It is more efficient for certain use cases, and has
a more modern path inside the kernel.

Adding POSIX 'E' error code constants for Windows

Believe it or not, Windows actually defines a few POSIX
'E' error codes (eg EINVAL). By adding them to libc, the Windows
bindings for things like `read()` become useful.
