[cc65] New environment routines

After some discussions with Stefan Haubenthal, I've written new routines for
handling the environment. Available functions are putenv and getenv, plus the
environment pointer _environ. The module that defines _environ will call a
constructor named initenv, which is not defined and must come from platform
code. For platforms that have some form of environment (Lunix?), this
constructor can initialize _environ, which makes its values available to the
program. Other platforms that want to use the environment routines must supply
an empty constructor. Using a dummy module that contains

       	.export	initenv
       	initenv = return0

is sufficient.

Existing platform dependent getenv routines (which all returned NULL) have
been removed.
