Fixed a problem with the internal Owner ID allocation and
deallocation mechanisms for control method execution and
recursive method invocation. This should eliminate the
OWNER_ID_LIMIT exceptions and "Invalid OwnerId" messages
seen on some systems. Recursive method invocation depth
is currently limited to 255. (Alexey Starikovskiy)

Completely eliminated all vestiges of support for the
"module-level executable code" until this support is
fully implemented and debugged. This should eliminate the
NO_RETURN_VALUE exceptions seen during table load on some
systems that invoke this support.

Fixed a problem within the resource manager code where
the transaction flags for a 64-bit address descriptor were
handled incorrectly in the type-specific flag byte.
Consolidated duplicate code within the address descriptor
resource manager code, reducing overall subsystem code size.
