Initial import of JTAG ICE mkI support.

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
