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.

Disable auto erase for flash. When the -U option with flash memory is
specified, avrdude will perform a chip erase before starting any of the
programming operations, since it generally is a mistake to program the flash
without performing an erase first. This option disables that. However, to
remain backward compatible, the -i, and -m options automatically disable the
auto erase feature.
without performing an erase first. This option disables that.
Auto erase is not used for ATxmega devices as these devices can
use page erase before writing each page so no explicit chip erase
is required.
Note however that any page not affected by the current operation
will retain its previous contents.
@item -e
Causes a chip erase to be executed. This will reset the contents of the
flash ROM and EEPROM to the value `0xff', and is basically a
flash ROM and EEPROM to the value `0xff', and clear all lock bits.
Except for ATxmega devices which can use page erase,
it is basically a
prerequisite command before the flash ROM can be reprogrammed again.
The only exception would be if the new contents would exclusively cause
bits to be programmed from the value `1' to `0'. Note that in order
