XSB Src (SVN)-old

Added conditional windows phraseology to eliminate inconsistent dll
linkage warnings. Also added functionality to intern_term by adding
another flag argument to all return of address of interned term tagged
as integer.

changed the compilation option for DLLs from MT to MD
recompiled dlls
minor changes in dbdrivers

dbdriver: NULL() replaced with NUL(_)
manual: typos
slgdelay: commented out spurious printf's

Deleted error processing for situation that shouldn't arise during type
conversiont, and just throw an internal error instead.

if 'term' is specified as a field type and the field is empty or space-only, return that atom ' ' rather than a variable.
Also, issue an error/warning if can't convert to term.
I think it is better than before.

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.
