Follows the IEEE Std 1003.1, 2013 Edition (The Open Group Base Specifications Issue 7) as much as libc implementations do, along with some common additions that are required by Crystal.

Bindings are automatically generated with CrystalLib from C headers.

Crystal only supports the x86 and x86_64 targets for now, but we should be capable to generate bindings for whatever POSIX C implementation. Each target will be checked when headers have been verified to be compliant.
