joerg_wunsch 2d236ed812 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 e44b866716 Try reading/writing more than one byte at a time, to improve overall
performance.

Note that many consumers still read one byte at a time though.

This patch has once been submitted to me by Bernd Walter
<ticso@cicely.de>, minor tweak by me (mainly to get it running under
Linux, too).

joerg_wunsch b49dc8f645 Mega-commit to bring in both, the STK500v2 support from Erik
Walthinsen, as well as JTAG ICE mkII support (by me).

Erik's submission has been cleaned up a little bit, mostly to add his
name and the current year to the copyright of the new file, remove
trailing white space before importing the files, and fix the minor
syntax errors in his avrdude.conf.in additions (missing semicolons).

The JTAG ICE mkII support should be considered alpha to beta quality
at this point.  Few things are still to be done, like defering the
hfuse (OCDEN) tweaks until they are really required.  Also, for
reasons not yet known, the target MCU doesn't start to run after
signing off from the ICE, it needs a power-cycle first (at least on my
STK500).

Note that for the JTAG ICE, I did change a few things in the internal
API.  Notably I made the serial receive timeout configurable by the
backends via an exported variable (done in both the Posix and the
Win32 implementation), and I made the serial_recv() function return a
-1 instead of bailing out with exit(1) upon encountering a receive
timeout (currently only done in the Posix implementation).  Both
measures together allow me to receive a datastreem from the ICE at 115
kbps on a somewhat lossy PCI multi-UART card that occasionally drops a
character.  The JTAG ICE mkII protocol has enough of safety layers to
allow recovering from these events, but the previous code wasn't
prepared for any kind of recovery.  The Win32 change for this still
has to be done, and the traditional drivers need to be converted to
exit(1) upon encountering a timeout (as they're now getting a -1
returned they didn't see before in that case).
