patch #9507: Fix UPDI chip erase
* lexer.l (family_id): New keyword.
* config_gram.y: (Ditto)
* doc/avrdude.texi: Document new keyword
* avrdude.conf.in: Add family_id for avr8x devices
* avr.c: Pass error code up.
* jtag3.c: Pass error code from memory read up; implement
jtag3_read_sib()
* libavrdude.h: Add new items.
* main.c: Implement different chip erase handling required
for UPDI devices.
