Joerg Wunsch f5882fc781 Implement and document a libusb-based USB transport for the JTAG ICE
mkII.

The serial transport methods have been moved out into a record of
function pointers for that purpose, defaulting to the actual serial
connection that natively applies to the hosting system.  Iff inside
the JTAG ICE mkII handler a port name starting with "usb" has been
detected, the record of function pointers is switched to USB.
Optionally, a serial number might be specified, so only the JTAG ICE
mkII matching the given serial number will be opened.  The match is
done right-to-left, so only the least significant bytes of the serial
number need to be given.

In order to make the change as least intrusive to existing drivers as
possible, the entire naming scheme of the serial_foo() function entry
points has been maintained as access macros that encapsulate these
into the respective indirect function calls via serdev->foo().

Joerg Wunsch 8a91d9afec Add "efuse" sections to the ATmega164/324/644 definitions.
Iff enter_progmode failed with RSP_ILLEGAL_JTAG_ID, give the user a
hint that their JTAGEN fuse might be unset.

Joerg Wunsch 2be5a10ed8 Fix a signedness bug when shifting bits; this caused the length field
of the packet to occasionally been misinterpreted as a negative
number.

When discarding a packet for being overly long, restart the state
machine instead of attempting to drop a preposterous amount of data.
It is unlikely in that case that preposterous amount of data would
ever arrive, so rather attempt to re-align the reading algorithm
(supposedly resulting in a timeout and retransmit).

Joerg Wunsch 97926d510f Rename the BAUD_xxx baud rate defines to PAR_BAUD_xxx to avoid a name
clash with the Win32 API names for baud rates.

Joerg Wunsch a5a700f7a1 Quite some cleanup of the JTAG ICE mkII stuff.
. Implement the new EECRAddress field in the device descriptor that is
  required by the 4.x firmware; make an uneducated guess about what
  firmware requires what length of device descriptor -- perhaps Atmel
  can be convinced to publish an official matrix for that.

. Specify EECR in the config file where required.  Obviously, only
  locations that differ from the 0x3c default are mentioned in the
  XML files, so by now, this only affects the AT90CAN128 for us.

. After clarification with Atmel, EnablePageProgramming should really
  default to 1, and only cleared if specified by an XML parameter.  So
  far, only the XML files for the ATmega256x and ATmega406 do specify
  it at all, and they specify a 1, too.

. Drop the entire OCDEN fuse heuristic.  If OCDEN is unprogrammed at
  startup, issue a warning that single-byte EEPROM updates won't be
  possible.  Leave it to the user to program the fuse if desired.
  That way, we won't run into any issue of prematurely wearing out the
  hfuse EEPROM cell.  Interestingly enough, this also solved the
  problem of the target not restarting from scratch upon sign-off.

Joerg Wunsch 566a0ec0e6 Make the retrier in case of rx timeouts more robust, by increasing
the receive timeout once a timeout happened.
