Fix error reporting by avr_write_byte().

Fix setting of status LEDs under various write-fail conditions.

Add a flag to indicate that a memory type requires the device to
possibly be powered off and back on after a write to it.  This is due
to a hardware problem on some Atmel devices, see:

	http://www.atmel.com/atmel/acrobat/doc1280.pdf

Add greater verbosity to the part-display code when verbose>1 to
display avrprog's encoding of the defined programming instructions.
This is primarily for debugging purposes.


Part updates:

  * add the AT90S4414 part

  * add fuse and lock bit access instructions for the AT90S1200,
    AT90S4434, and AT90S8515.

  * add the pwroff_after_write flag to the fuse bits for the AT90S2333
    and AT90S4433 parts
