Joerg Wunsch e59b190654 * jtag3.c (jtag3_initialize): Fix a buffer overflow by limiting ...

the flash page cache size to at most "readsize".  For Xmegas with
a page size of 512 bytes, the maximum USB packet size was
overflowed, and subsequently, a memmove copied beyond the end of
the allocated buffer.
* jtag3.c (jtag3_read_byte): Add the correct offset also for the
various flash regions, so reading the apptable or boot regions
yields the correct data.
