First stab at an implementation of the STK500 parallel programming 

feature (v2 firmware only), named "stk500pp".  Still not yet
complete: EEPROM writes not working, documentation missing, only
ATmega16 parameters available in avrdude.conf.in, some parameters
not yet implemented.

* avrdude.conf.in: Add sample parameters for PP mode to ATmega16.
* avrpart.h: Add the parallel programming control parameters.
* avrpart.c: (Ditto.)
* config_gram.y: Add stk500pp configuration grammar.
* lexer.l: Add stk500pp token recognition.
* stk500v2.h: Add declaration for stk500pp_initpgm().
* stk500v2.c: Add stk500pp implementation.
