XSB Src (SVN)-old

Implemented version of message queues for single-threaded engine, to
support interrupts with general goals.

Added interrupt_with_goal and handle_goal_interrupt. These allow a
computation to interupt itself from Prolog with any goal.

Fixed minor bug in timed_call test.

Fixing xsb testsuite for MT

Changed boundary condition on term stacks in 2 term traversal routines. This fixes 2 memory errors uncovered by Valgrind.

got rid of -ansi -pedantic

Hopefully, a fix to a transient problem w. immutable.

fixed the makefile and couple of casts so that the c_calling_XSB example will compile and with fewer warnings.

Disabled dissasembly for immutable modules. Debug messages for immutable set on w. verboseness flag.

Debug messages for immutable only come on w. verboseness level set.
