features required for HVSP support.
* lexer.l: (Ditto.)

Joerg Wunsch 8bdbf1774e 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.

Joerg Wunsch 04831af970 Mega-commit to bring in both, the STK500v2 support from Erik
Walthinsen, as well as JTAG ICE mkII support (by me).

Erik's submission has been cleaned up a little bit, mostly to add his
name and the current year to the copyright of the new file, remove
trailing white space before importing the files, and fix the minor
syntax errors in his avrdude.conf.in additions (missing semicolons).

The JTAG ICE mkII support should be considered alpha to beta quality
at this point.  Few things are still to be done, like defering the
hfuse (OCDEN) tweaks until they are really required.  Also, for
reasons not yet known, the target MCU doesn't start to run after
signing off from the ICE, it needs a power-cycle first (at least on my
STK500).

Note that for the JTAG ICE, I did change a few things in the internal
API.  Notably I made the serial receive timeout configurable by the
backends via an exported variable (done in both the Posix and the
Win32 implementation), and I made the serial_recv() function return a
-1 instead of bailing out with exit(1) upon encountering a receive
timeout (currently only done in the Posix implementation).  Both
measures together allow me to receive a datastreem from the ICE at 115
kbps on a somewhat lossy PCI multi-UART card that occasionally drops a
character.  The JTAG ICE mkII protocol has enough of safety layers to
allow recovering from these events, but the previous code wasn't
prepared for any kind of recovery.  The Win32 change for this still
has to be done, and the traditional drivers need to be converted to
exit(1) upon encountering a timeout (as they're now getting a -1
returned they didn't see before in that case).
