XSB Src (SVN)-old

added the ability to use user-defined types to proc_files: user can use
add_cvt_type_hook/2 to specify conversion hooks for specific types, eg, a time-hook may take something like '9:8:7' and return time(9,8,7).
Some refactoring of code.

squash the DISABLE_LINUX_COMPILER_WARNING macro on windows.
Replace /MT with /MD flag in windows makefiles

Added hook to not remove .xwams when running in gc-test mode.

IDG traversal routines using CNs instead of SFs, and code cleanup.

Finished (I think) updating code so that IDG traversal for meta-predicates
works on call nodes rather than SF. (I didn't change xsb_compute_scc, which can only work on
interior IDG nodes, anyway).

Also do a bit of code cleanup, removal of dead code, and rationalization of code within files.

No longer needed.

Changed my mind. Now a Mod:Term term in a structure (not in predicate
positions) is left as Mod:NTerm, where Term is transformed to
NTerm. So the module modifier is left alone and does not affect the
Term. This is what the compiler would do.
