Xmega page erase implementation for JTAGICEmkII

Browse Source 
* jtagmkII.c: Handle flash pages sizes > 256 bytes, implement
page_erase() method
* avrdude.conf.in: Change flash pagesize for all Xmega devices
to 512 bytes
* avr.c: Implement auto_erase, using page_erase if available
* avr.h: Remove unused parameters from avr_read(), replace
unused parameter in avr_write)() by auto_erase
* stk500v2.c: Handle flash page sizes > 256 bytes
* update.c (do_op): Handle new updateflags parameter
* main.c: Implement auto_erase as page_erase if possible
* update.h (enum updateflags): New enum
* pgm.h (struct programmer_t): Add page_erase method
