libvmcp: Add common vmcp code to the lib

This patch prevents code duplication in vmcp related programs.
Some applications such as vmur, vmcp, and lsqeth
use z/VM CP commands to query information. Each program
uses its own defines and code.

Supply a library and common header file to use common code.
