Nomenclature change. BDM is a specific type of OCD
(On chip debugging). Wiggler is the parallel port box controlled
by Wigglers.dll. The faster target box from Macraigor Systems
is not a wiggler.
* ocd.c:
* ocd.h:
* ppc-bdm.c:
* ser-ocd.c:
Replace all instances of "wiggler_" with "ocd_" and change most other
instances of "wiggler" to "ocd" or "ocd device" depending on context.
* config/m68k/monitor.mt: remove remote-wiggler.o from TDEPFILES
until OCD with that target is supported again.
