This is a relatively significant edit that brings the Arduino copy of

optiboot up-to-date with the optiboot source repository as of Jun-2011
(the last changes made in the optiboot repository were in Oct-2010)

This adds support for several plaforms, fixes the "30k bug", and
refactors the source to have separate stk500.h, boot.h, and pin_defs.h

These are the arduino opticode issues fixed:
http://code.google.com/p/arduino/issues/detail?id=380
    optiboot has problems upload sketches bigger than 30 KB
http://code.google.com/p/arduino/issues/detail?id=556
    update optiboot to the point of the latest optiboot project sources.

These are issues that had been solved in the optiboot source aready:
http://code.google.com/p/arduino/issues/detail?id=364
   optiboot leaves timer1 configured when starting app, breaks PWM on
   pin 9 and 10.  (fixed with a workaround in arduino core.)
   aka http://code.google.com/p/optiboot/source/detail?r=c778fbe72df6ac13ef730c25283358c3c970f73e
   Support for ATmega8 and mega88.
   Fix fuse settings for mega168 _ISP targets
   Additional new platforms (mega, sanguino)

http://code.google.com/p/optiboot/issues/detail?id=26
   Set R1 to 0  (already in arduino code)
http://code.google.com/p/optiboot/issues/detail?id=36&can=1
   Fails to build correctly for mega88

After this commit, the only differences between the Arduino optiboot.c
and the optiboot repository optiboot.c are cosmetic.
