* avrdude.conf.in: Add avr910 and pavr programmers.

* config_gram.y: Add parsing of avr910 programmer.
* lexer.l: Add avr910 token.
* avr910.c: [this is still work in progress]
Add some debug output.
Add probe for programmer presense.
* main.c: Set port to default_serial if programmer type is avr910.
