fhandler.h throughout. Remove device argument and unit arguments from fhandler
constructors throughout. Remove pc arguments to fhandler functions and use
internal pc element instead, throughout. Use dev element in pc throughout.

fhandler class. Use correct methods for fhandler file names rather than
directly accessing file name variables, throughout.
* Makefile.in (DLL_OFILES): Add devices.o, fhandler_fifo.o
