Add few docs and implementation of strcpy and strcat. Summary: This patch illustrates some of the features like modularity we want in the new libc. Few other ideas like different kinds of testing, redirectors etc are not yet present.

Add implementations of POSIX mmap and munmap functions. Summary: A set of of linux x86_64 internal syscall helpers have also been added. This change does not try to be perfect with respect to OS and machine abstractions. A TODO note has been added at places where such abstractions would help and make the arrangement scalable and cleaner. Addressing the TODOs and building such abstractions is not in the scope of this change. It is hoped that follow up changes cleaning up the problem areas and addressing the TODOs will better illustrate the need for the changes. This change also does not try to imitate mmap and munmap implementations of other libcs. The idea here is to put in the bare minimum required to obtain a working mmap and munmap, and then add the rest of the functionality on an as needed basis.

[libc] Add Initial Support for Signals Summary: This patch adds signal support on Linux. The current implementation gets the SIG* macros and types like `sigset_t` from <linux/signals.h> This patch also adds raise(3), and internal routines `block_all_signals` and `restore_signals` Reviewers: sivachandra, MaskRay, gchatelet Reviewed By: sivachandra Subscribers: libc-commits, mgorny, tschuett Differential Revision: https://reviews.llvm.org/D74528

Illustrate a redirector using the example of round function from math.h. Setup demonstrated in this patch is only for ELF-ish platforms. Also note: 1. Use of redirectors is a temporary scheme. They will be removed once LLVM-libc has implementations for the redirected functions. 2. Redirectors are optional. One can choose to not include them in the LLVM-libc build for their platform. 3. Even with redirectors used, we want to link to the system libc dynamically.
