Split higher level parallel port programmer code off from ppi.c into

its own file par.c, leaving low level parallel port accessor routines
in ppi.c to help with portability.  Change the programmer type to
'PAR' now instead of 'PPI' - 'PAR' represents the parallel port
programmer type.

Be more liberal with 'static' function declarations within the
programmer implimentation files - these functions should never be
called directly - always use the programmer function references.

There are still a few places in 'main.c' that directly reference the
parallel programmer explicitly (par_getpinmask).  These should be
fixed somehow.

Axe a few unused functions.
