First implementation of ATxmega support. By now, only the

Browse Source 
PDI mode of the STK600 is supported.  Single-byte EEPROM
(and flash) updates do not work yet.
* avr.c: "boot" memory is a candidate memory region for paged
operations, besides "flash" and "eeprom".
* avrdude.conf.in: add ATxmega128A1 and ATxmega128A1revD
* avrpart.h: add the AVRPART_HAS_PDI flag (used to distinguish
ATxmega parts from classic AVRs), the nvm_base part field, and
the offset field for a memory region.
* config_gram.y: add "has_pdi", "nvm_base", and "offset"
* lexer.l: (Ditto.)
* main.c: disable auto_erase for ATxmega parts
* stk500v2.c: implement the XPROG functionality, and divert to
this for ATxmega parts
* avrdude.1: Document the changes.
