Siva Chandra Reddy 9364107cf3 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.

Siva Chandra 4380647e79 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.
