Various fixes for Xmega devices.

Browse Source 
* avrdude.conf.in: Correctly declare EEPROM page sizes for
all Xmega devices (0x20 instead of 0x100).
* avr.c: If a memory region has a page size declared, try
using the paged IO routines regardless of the target memory
name.  Xmega EEPROM requires to be written in paged mode.
Correctly use a long (rather than unsigned long) variable to
evaluate the success status of the paged mode write attempt.
* stk500v2.c: Don't apply TIF space offsets twice (bug #27995:
AVRDUDE 5.8svn fails to program and read XMEGA); use
stk500v2_loadaddr() prior to paged mode (EEPROM and flash) writes,
otherwise programming of flash areas will fail; while being there,
check the return value of stk500v2_loadaddr() everywhere; use the
correct write/erase mode bits (same as AVR Studio does).
