macro language and stream library changes

	addition of 3-word argument to c/lc macro in stack.def

	force case-sensitive assembly in stack.def so certain things
	in it work

	comment the change in scalars() for referencing
	dynamic item displacements while the stack is growing.
	also in stack.def

	change to repoussez routine in aquiform.msm
	repoussez is ungetc() for the bit stream read channel
	change affects byte sizes which do not divide into 24
	RDATA overflowed backwards is now compensated
	with RDATAC changed back into range and read pointer
	register q decremented

	changes in aquiform.def to accommodate writes of bytes
	larger than 16 bits when the bit stream write channel
	is in 16-bit mode for networks / 16-bit peripherals.
	wsr instruction should cause one write cycle or none
	but never two writes
	add some integer functions to stream libraries
