bug #34302: Feature request : device configuration with parent classes

(not in original patch) 
* avrpart.c: New function avr_dup_opcode. avr_dup_mem/avr_dup_part-
	functions now duplicate the opcodes in their op-array to avoid memory leaks.
* doc/avrdude.texi: Added description of part parent f

bug #34302: Feature request : device configuration with parent classes
* config_gram.y: Added part parent rule and allow overwriting existing
data at several places
* avrdude.conf.in: Added description comment and m328/m328p as example
* avrpart.c: avr_dup_mem-functions now copy buf and tags memory block
only they are already allocated.
* lexer.l: Added parent as valid token
(not in original patch)
* avrpart.c: New function avr_dup_opcode. avr_dup_mem/avr_dup_part-
functions now duplicate the opcodes in their op-array to avoid memory leaks.
