Add schedule params & priority pthread functions
Fixes#609. Provides bindings to `pthread_getschedparam`, `pthread_setschedparam` and `pthread_setschedprio` functions.
P.S. My first PR in such a project.
P.P.S. `libc-test` crashed at building stage with a lot of errors, so I hope `travis` will do a check.
P.P.P.S. These functions are tested to work on Linux (Ubuntu 14.04) with my own crate. I will release it next week, it provides ability to control thread schedule policies and priorities.
Add experimental L4re support
This PR introduces a UNIX-alike target for the l4re microkernel
operating system. While this system is not a UNIX system at all, it is
easiest to use the POSIX interface and hence benefit from common
definitions.
This version is a very early draft, only the basic data types have been
verified and most of the complex data types (structs and unions) have
not been ported yet.
Thanks to TobiasSchaffner for providing his patched version, to verify some assumptions.

Adding missing structs from linux/user.h
Adding structs from linux/user.h (or sys/user.h depending on OS version). This adds the linux user_regs_struct and user struct from sys/user.h into libc for x86 and x86_64. Also, bumping the version number.
As an aside, I was wondering if this was also the right place to add the bit offsets for the [EFLAGS register ](https://en.wikibooks.org/wiki/X86_Assembly/X86_Architecture#EFLAGS_Register)? These aren't defined anywhere in the linux system libraries instead the definition seems to just be in the x86 and x86_64 documentation but they are useful for anyone looking to interpret eflags. If libc is the right place for these constants I'd like the opportunity to add them before it's merged in. :)
Fixed the issues that prevented the libc_tests that are generated from passing. Also, fixed struct names and types to be representative of the linux source files.
