XSB Src (SVN)-old

curr_sym.P, std_xsb.P : added
subgoal_property/2,variant_subgoal_prperty/2 as "standard" predicates.
This replaces the following predicates (which are obsolete but are
still working):

incr_is_invalid/1,incr_is_invalid/3, incr_invalid_subgoals/1,
is_incremental_subgoal/1,

Also added some code for set_subgoal property, which isn't finished

standard.P tables.P
moved check_table_option/4 from standard to tables

tables.P, tr_utils.c
in set_tif_property changed subgoal_depth,answer_depth to
subgoal_size,answer_size. This isnt a user predicate, so it shouldn't
pose a problem:

get_calls/1 fixed to allow explicit module in input

typo

added sleep_ms/1 to sleep for milliseconds rather than seconds.
recompiled

some changes to get configure and partly makexsb work under cygwin

Added documentation to include str_repl/4.
Updated documentation for proc_files predicates.
Updatd tables documentation to mention intern_termhash.

Added documentation for intern_termhash/2.

Added better error checking to str_repl.

Added str_repl to replace substrings in strings. Found myself rewriting
versions of this. Performance could be improved, but at least it's here.

Added interm_termhash builtin. (Thought this had been done...)

Add decl to eliminate MSVC warning.
