Implement EEPROM access through debugWire.

Browse Source 
* jtagmkII.c: Extend the jtagmkII_read_byte() and
jtagmkII_write_byte() methods to handle EEPROM through
debugWire.

* avrpart.h: Implement the "flash instruction" parameter.
* config_gram.y: (Ditto.)
* lexer.l: (Ditto.)
* avrdude.conf.in: (Ditto.)

* avrdude.1: Document the EEPROM access through dW.
* doc/avrdude.texi: (Ditto.)

* tools/get-dw-params.xsl: Extend to extract the flash
instruction field.
