XSB Src (SVN)-old

Updated section on timed_call to include timed_call_modify and current_timed_call.

Minor changes. Changed get_timed_call_index to get_interpreter_index, and
also use this for abort/1.

Implemented timed_call_modify, and current_timed_call.

Added utility predicate to tables to print out tabled predicates with number
of calls and answers. Makes it easier to track down tables that should
have been abolished but aren't.
In writing it descovered a minor bug in predicate_property that I also fixed.

Refactored slightly to provide new slightly lower-level interface to this
functionality.

Added definitions for get_mod_for_psc, and get_mod_name.

Improved an error message in one cse when getc returns an error. (Previously
everything was treated as eof.)

Removed logging, and improved (I think) a comment.

Added new versin of c_string_to_p_charlist that includes length of
string, to allow construction of code lists with '0' bytes in them.

Change get_mod_for_psc to be a macro; so delete code here.
