XSB Src (SVN)-old

A new set of routines that support creating and using "Prolog Databases"
in XSB. A Prolog DB is Prolog term that represents a set of rules. Users
can create sets of rules, pass them aroung, and call goals in them.
These Prolog DBs are represented as a Prolog term which implements a trie,
with hash tables at each branch point. They are asymptotically quite
efficient. See documentation in User Manual 2 under Libraries.

Added documentation on interning terms and using (e.g.)
:- table p/2 as intern.

Updated for release of 3.5.

Some extra minor changes.

Major rewrite of incremental tabling system; updated biblio references
and credits.

documented new flags, concat_atom running backwards.

Added documentation for character sets: renamed ASCII to LATIN-1,
added cp1252 (code page 1252) for windows, and we now associate
a character set with a stream.

Added lots of casts to remove (hopefully) spurious compiler warnings.

fixed title length and typo

Added include of cell_xsb_i.h for some defines that seem to have been moved.
Also added primitive code to get and printout detailed error diagnostics.
It's called only after SQLDirverConnect for now. Should be better integrated
and be allowed to be called for all bad returns. Also maybe return error
messages as a string back to caller, as new option in odbc_error handling.
