bsd dd7d98ccf4 Move pin definitions to their own file.
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.

bsd 46a4582009 Rearrange the pinout for the programmer to be a little more logical.
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.

bsd b211c95bfe The program was getting too large for a single file. Split it up into
more modular pieces.

Also, accept command abbreviations as long as they are not ambiguous.
