CP/M ulibc

The aim of this project is to develop minimalistic C library for CP/M using
plain C and Z80 assembly language. It should compile with LLVM's Clang patched
for Z80 architecture support and GNU as from binutils package built with
--target=z80-none-elf flag passed to its configure script.

Before starting a build process of this library, the settings (paths mostly)
held in compiler.def and emulator.def files need to be adjusted.

The tests are started by invoking make test. In order to proceed, they require
Joseph Allen's CP/M emulator (see https://github.com/jhallen/cpm.git).
