Use major/minor elements rather than units and device numbers previously in
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
* dcrt0.cc (dll_crt0_1): Call device::init.
