XSB Src (SVN)-old

Added a note about updating project news.

fixes to last change
had removed memory counters for sequential system!

Removed global counters for stastics (including mem space values)
from multi-threaded system if not in debug mode.
Those counters were hurting scalability on a multi-processor badly

Added context.h to list of includes, since CTXTDeclc is required by the
funtion prototype for bld_boxedfloat in cell_xsb.h and cell_xsb.h is included

Fixes to last changes - some wrong files were commited by mistake

replaced shared struct manangers with malloc
which improves scalabilty on a multi-processor

that required a number of small fixes to have coherency
between shared and private struct managers

Just moved some redefines, which change the meaning of the unify_xsb() macro,
closer to the use of that macro. At least now it's easier to see what's
going on.

Changed source definition of \= slightly so compiler generates slightly
better code. Really should be added to the jumpcof instruction and coded
in C.

Checkin new .xwam files due to compiler improvement of compiling
some conditions in if-then-else.

Change compiler to include all the jump_cof predicates as deterministic
non-state-changing inlines for conditions. (Somehow they weren't there,
so some of them still resulted in choicepoints being laid down. I discovered
it in looking at flatten, where is_list in a condition still resulted in
a choicepoint.)
Also check in the several .xwam files that changed due to this compilation
improvement.
