+ * Mega patch merge to change the format of the object IDs to
+ loosen the dependency between the SCORE and the various APIs.
+ There was considerable work to simplify the object name management
+ and it appears that the name_table field is no longer needed.
+ This patch also includes the addition of the internal mutex
+ which is currently only used to protect some types of allocation
+ and deallocation. This significantly can reduce context
+ switch latency under certain circumstances. In particular,
+ some heap/region operations were O(n) and had dispatching
+ disabled. This should help enormously. With this merge,
+ the patch is not as clean as it should be. In particular,
+ the documentation has not been modified to reflect the new object
+ ID layout, the IDs in the test screens are not updated, and
+ _Objects_Get_information needs to be a real routine not inlined.
+ As part of this patch a lot of MP code for thread/proxy blocking
+ was made conditional and cleaned up.
+ * src/bdbuf.c: Modified as part of above.
