XSB Src (SVN)-old

Atom_codes and atom_chars are no longer inline builtins. The problem
is that these predicates may require heap expansion, and if the
explicit call is optimized away, the number of registers to pass to
heap expansion is unknown, leading to a core dump when they are called
on large atoms (or large code lists).

recompiled win64 pkgs

changed the default on windows32 to __cdecl
For stdcall'ers, configure --with-stdcall
Crucial changes in export.h, config files, and various package NMakefiles.

Note: Win64 ignores _stdcall and always uses __cdecl.

minor typo

fixes in url_property. recompiled dlls

minor improvements, clarifications

base64_enc.c: casts to quite compiler.
biassert.c: handle 0-ary predicates for profiling.
builtin.c: minor cleanup around profiling (plus array overflow fix.)

Modified printout to include a predicate only if it has at least 0.1% of
the total time.

fixed a typo, which broke http PUT requests

Fixed a couple of bugs in the SCC analysis of max_scc_subgoals_header.
