avr.c avr.h fileio.c term.c :

     Change the avrpart data structure so that the typedef AVRMEM is
     used as an index into an array for the sizes of the memory types
     and also for pointers to buffers that represent the chip data for
     that memory type.  This removes a lot of conditional code of the
     form:

		switch (memtype) {
			case AVR_FLASH :
		 	...
		}

     Also, re-code avr_read_byte() and avr_write_byte() to properly
     handle the flash memory type without having to tell them whether
     they should program the high byte or the low byte - figure that
     out from the address itself.  For flash memory type, these
     routines now take the actual byte address instead of the word
     address.  This _greatly_ simplifies many otherwise simple
     operations, such a reading or writing a range of memory, by not
     having to worry about whether the address starts on an odd byte
     or an even byte.
