introduce a Var_Substi to substitute on intervals.
Since we don't really know how to change Var_Subst and dependent functions,
we cheat, and copy the string to a buffer instead.

Clean-up the parser a bit: reorganize the include files lookup function:
introduce a resolve_include_filename function that figures out the full name
of the file, introduce a handle_include_file that does all the include file
handling, and rename the functions into handle_xxx_include, so that we
can remove most comments.

Rename ParseIsCond into handle_bsd_command, cut most of its code into
constituent functions.

Semantic changes:
- follow the rules that, if an optional construct does not parse correctly,
then it's not a real extension, and give the normal parser a chance to figure
it out. If the syntax checks out, semantic errors ARE real errors.
- allow variables to not be defined in include file names, no reason not to.
