core: cfg.lex support for undefned env vars

Feature Request GH #2967 for undefined defenv

Add new keywords for preprocessing:

- #!trydefenv - The same as #!defenv, except if the variable is
  undefined, the def value will be undefined as well.

- #!trydefenvs - The same as #!defenvs, except if the variable is
  undefined, the def value will be undefined as well.
