Bug fixes #1 and #3 are (in my opinion) already present.

I adopted your fix for bug #2.

I'm not yet convinced about the cleanups (as partially already
mentioned).

While writing my own AVR109 compliant (SRAM) buffered bootloader I needed the attached butterfly.c changes.

Three bug fixes:

1. Word flash addresses (already fixed in master).

2. Absent butterfly_page_erase()
Seg fault when trying to program the eeprom only.

3. Terminal mode uses butterfly_read_byte_flash() to dump flash content. Original got byte order wrong.

Clean-up:

1. Skips address setting if the bootloader auto increments the address.

2. Allows multi-page load/write (if just the calling avr.c would take advantage of!).

For your perusal. Thanks, Enoch.
