XSB Src (SVN)-old

Made timed_call work with breaks.

Added cancel_sleeper_thread for making timed_call work with XSB/Ergo break.

Updates for timed_call additions.

added quotation to Windows paths so that pcre/curl/xpath packages could work for the cases when XSB is installed in directories that contain spaces.

Fixed a performance bug in tsiOrderedInsert in tst_insert.c to avoid
running a long list to insert a node in the proper location. Used a
"skiplist" idea. Only implemented one level, since that more than
handled my problem. Left warning if more levels would be needed for
faster access.
The other files are updated to try to support the same functionality
in the multithreaded engine. I'm unable to test those changes now, so
I'm depending on others to test this...

Changed a type from long to int, so quiets my compiler warnings.

Fixed some broken format specifications in printf's. Used only in debugging,
I believe.

Fixed insert_cpred() to add type of T_FORN

added a note that XSB can't be built under cygwin32-WOW, ie, if cygwin32 is installed on a 64 bit Windows. Probably a tagging problem.

Forgot to change title.
