bug #30451: Accessing some Xmega memory sections gives not

Browse Source 
supported error
* stk500v2.c: Handle all Xmega memory sections (except
"prodsig" which is not documented in AVR079)
* fileio.c: Treat the "boot", "application", and "apptable"
regions (which are actually subregions of "flash") all as
being flash, i.e. suppress trailing 0xFF bytes when reading
them
* avr.c: (Dito.)
