Added code to save space in namespaces. Currently #ifdef'ed out for compat.

Also added code from itcl-ng for better separation of concerns.

+	* generic/tclInt.h (Namespace):		   Added machinery to allow
+	* generic/tclNamesp.c (many functions):	   reduction of memory used
+	* generic/tclResolve.c (BumpCmdRefEpochs): by namespaces. Currently
+	#ifdef'ed out because of compatibility concerns.
+
+	* generic/tclInt.decls: Added four functions for better integration
+	with itcl-ng.

 	Extended the bytecode compiler initialization to recognize the
-	compilation of whole files (NRE enabled 'source' command) and
-	switch to the counting of absolute lines in that case.
-
-	Further extended the bytecode compiler to track the start line in
-	the generated information, and modified the bytecode execution to
-	recompile an object if the location as per the calling context
-	doesn't match the location saved in the bytecode. This part could
-	be optimized more by using more memory to keep all possibilities
-	which occur around, or by just adjusting the location information
-	instead of a total recompile.
-
-	Reworked the handling of literal command arguments in bytecode to
-	be saved (compiler) and used (execution) per command (See the
-	TCL_INVOKE_STK* instructions), and not per the whole bytecode.
-	This, and the previous change remove the problems with location
-	data caused by literal sharing (across whole files, but also proc
-	bodies). Simplified the associated datastructures (ExtIndex is
-	gone, as is the function EnterCmdWordIndex).
-
-	The last change causes the hashtable 'lineLABCPtr' to be state
-	which has to be kept per coroutine, like the CmdFrame stack.
-	Reworked the coroutine support code to create, delete and switch
-	the information as needed. Further reworked the tailcall command
-	as well, it has to pop its own arguments when run in a bytecode
-	context to keep a proper stack in 'lineLABCPtr'.
-
-	Fixed the mishandling of line information in the NRE-enabled 'for'
-	and 'while' commands introduced when both were made to share their
-	iteration callbacks without taking into account that the loop body
-	is found in different words of the command. Introduced a separate
-	data structure to hold all the callback information, as we went
-	over the limit of 4 direct client-data values for NRE callbacks.
