* jtag3_private.h (MTYPE_EEPROM_XMEGA): New define.
* jtag3.c (jtag3_write_byte): When updating flash or
EEPROM on Xmega devices, resort to jtag3_paged_write()
after filling and modifying the page cache.
* jtag3.c (jtag3_paged_write): use MTYPE_EEPROM_XMEGA
where appropriate.
* jtag3.c (jtag3_initialize): Open with debugging intent
for Xmega devices, so single-byte EEPROM updates will
work.
