Clean-up the Xmega erase functions.

Browse Source 
* jtagmkII_private.h: Add CMND_XMEGA_ERASE as well as
the various XMEGA_ERASE_* definitions (from updated
appnote AVR067)
* jtagmkII.c (jtagmkII_chip_erase): Correctly implement
Xmega chip erase based on CMND_XMEGA_ERASE.
* jtagmkII.c (jtagmkII_pre_write): Remove, this turned out
to be just a chip erase.
* jtagmkII.c (jtagmkII_program_disable): Don't try reading
"hfuse" for Xmega parts; they don't have it.
* main.c (main): Re-enable auto-erase.  It's been done
before (as "jtagmkII_pre_write") in jtagmkII_paged_write()
anyway.  Xmega boot and application flash areas should be
handled separately in the future, so auto_erase can only
affect the area just being programmed.
