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.

VAR_GLOBAL context, so make it the common case: rename the basic functions
to Var_Set_with_ctxt/Var_Append_with_ctxt, define Var_Set and Var_Append
as macros that specify VAR_GLOBAL, and use these.

Var_Parse and Var_ParseSkip (the code that figures out the variable name
up to eventual modifiers).

- remove globals curdir and objdir, stuff them into a structure, and pass
it around to the relevant functions.
- cut up most of main code into functions:
figure_out_MACHINE/ARCH, figure_out_CURDIR, setup_CURDIR_OBJDIR, setup_VPATH,
no_fd_limits, read_makefile_list, read_all_make_rules...
- simplify the code used to figure out curdir/objdir.
No semantic changes.

1.6.9 has changed relative to older versions. Sudo now starts
commands with a minimal environment containing the variables in the
env_keep and env_check lists. This behavior is configurable in the
sudoers file. Please see the "SECURITY NOTES" section in the sudo
manual.

and keeping track of a length, we just advance the char *, and ditch
the length. We can still get the length at the end of the top-level
functions to satisfy existing interfaces.
Much simpler code, less error-prone.

Extend the code a bit to be much more thorough in case of a recursive
expansion: shows exactly the cycle of variable names involved.

(causes .for loops to give weird results very infrequently, memory handling
was slightly wrong, but not enough to break things thoroughly).

Check the rtm_version before trying to print an entry. If the rtmsg has a
different version skip it and don't try to print it. Solves a SIGSEGV I have

- rename a few functions in var.c to names that make more sense.
- introduce Var_Deletei because it makes more sense.
- rewrite .for loops to use a local LoopVar construct to avoid looking up more
stuff.
- reformat var.c to near K&R
- rewrite most comments in var.c
shown to a few people. millert@ gave me his okay since it passes through
ports correctly.
