available.
* avr910.c (avr910_vfy_cmd_sent): New function.
(avr910_chip_erase): Add support for chip erase.
(avr910_enter_prog_mode): New function.
(avr910_leave_prog_mode): New function.
(avr910_initialize): Add code to select device type and enter prog mode.
(avr910_close): Leave programming mode before closing serial port.
(avr910_read_sig_bytes): New function.
(avr910_initpgm): Add avr910_read_sig_bytes method to pgm initializer.
* avrdude.conf.in: Add note about deprecating devicecode.
Change all occurences of devicecode to stk500_devcode.
Add avr910_devcode to a few parts for testing.
* avrpart.h (struct avrpart): Change devicecode field to stk500_devcode.
(struct avrpart): Add avr910_devcode field.
* config_gram.y: Add K_STK500_DEVCODE and K_AVR910_DEVCODE tokens.
Generate an error if devicecode is found in the config file.
Handle parsing of avr910_devcode and stk500_devcode.
* lexer.l: Handle parsing of avr910_devcode and stk500_devcode.
* pgm.c: Initialize pgm->read_sig_bytes field.
* pgm.h: Add pgm->read_sig_bytes field.
* stk500.c: Use stk500_devcode instead of devicecode.
