avr_read_byte_default() and avr_write_byte_default (resp.) by directly
calling the latter functions from within all programmers that don't
implement their own read_byte()/write_byte() methods. In turn, make the
read_byte() and write_byte() methods mandatory, and the cmd() method
(direct ISP command) optional instead (it's effectively mandatory for
any programmer using avr_read_byte_default()/avr_write_byte_default()
though). Remove all the pointless cmd() method stubs from those programmers
that don't need it.
Eliminate avr_read_byte() as it was now completely identical to
pgm->read_byte().

when closing the connection. They cause the activity LED on the ICE
to continue to flicker, and are not necessary anyway (the target
starts to run by itself when leaving programmng mode).
This is a partial fix for bug #18262: JTAGMKI/JTAG1 Reset Bug

that indicates whether the underlying communication can dynamically
change its speed or not. This flag is set for true serial
communication but clear for USB communication. Don't try to adjust
the speed when talking over a communication channel that doesn't
support it. (The Dragon does not even support the respective
parameter.)

The very basic functionality (paged flash read/write, erase, terminal
mode reads, fuse writes) works fine. There are still the following
issues right now:
. paged EEPROM write (i.e. through -U eeprom:w:...) only works on an
erased EEPROM
. byte-access flash and EEPROM writes (i.e. in terminal mode) fail
. documentation needs to be updated still
