Replace the fallback of avr_read_byte() and avr_write_byte() to

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().
