XSB Src (SVN)-old

test added for abolish_nonincremental_tables/1.

Fixed outstanding bug in incremental tabling. Structure managers required a structure to be at least 2 words long, but smKey structures were 4 bytes.
So I redefined the size of KEY structures to be 4/8 bytes on 32/64 bit machines, and created a SM_DeallocateSmallStruct that handles structures of 1 word.
Regular structure managers still require 2 words.

Defined trans_depends/affects tables as opaque -- they are internal and are abolished at the beginning of each call.

Added condition to ifdef so that GENERAL_TAGGING is not enabled for 64-bits.

Changed from disassembling to a file named "stdout" to stdout.

Changed message for disassemble as per Peter Ludemann's suggestion.

Return successfully for SQL_SUCCESS_WITH_INFO for call to execute.
(Needed to allow PRINT stmts, pointed out by Miguel.)

Added missing ;
(Interestingly, this only showed up in -mt compilation, since without -mt
a macro introduced an "extraneous" ; which masked the error.)

Committing with new version (I hope)

Changes for release (hopefully soon).
