New function: replace-env.
Using this new function together with env, it's now possible
to save the set of environment variables, clobber it to a
specified set (possibly empty) and then restore it.
Useful for improved security in running child processes.
* lib.[ch] (chk_substrdup_utf8): New function.
* sysif.c (replace_env): New function.

* sysif.h (replace_env): Declared.
* txr.1: Documented.
