patch #9507: Fix UPDI chip erase
* libavrdude.h (PROGRAMMER): add unlock method
* avr.c (avr_unlock): Generic unlock function
* jtag3.c: Implement unlock feature; avoid calling
jtag3_edbg_prepare() and jtag3_edbg_signoff() on XplainedMini
boards to work around a bug in early firmware versions;
implement "userrow" memory region
* main.c: Call avr_unlock() rather than avr_chip_erase() when
encountering a locked UPDI chip
