First pass at providing feedback via the optionally connected leds. I
don't actually have any of these attached to my programmer, so I can
only guess as whether this is toggling them on and off correctly.
Also, enable and disable the optional 74367 buffer.

Provide hooks to support a buffered programmer, pin 6 is now used to
enable a buffer that can be used to isolate the target system from the
parallel port pins. This is important when programming the target
in-system.
Totally change the way the pin definitions are defined. Actually
set/clear pins based on the way more intuitive pin number, instead of
PPI data register, bit number combination. A table of pin data is
used so that any hardware inversion done by the parallel port is
accounted for, what you set is actually what appears at the pin.
Retain the old method for handling Vcc, however, because the hold
method is much easier to use when setting / retrieving multiple pins
simultaneously.

prompted.
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.

only via main() so that the exitspecs are properly applied.
When reading input data from a file, remember how many bytes were read
and write and verify only that many bytes.
Don't complain when an input file size is smaller than the memory size
we are programming. This is normal.

to get the history capabilities working yet, but even so, it does
better handling of the prompt and strips newlines for us, so it's
still a win.
Add a few new commands for terminal mode: help, sig, part, erase.
Display rudimentory help using the help command.
Add some function prototypes.
