The old implementation has a big local_irq_save() / restore() around the
endpoint re-fill routine. This disables interrupts for a long time,
psossibly causing lost interrupts.
The new implementation works around this by disabling the USB (UDP)
interrupt only, rather than disabling all interrupts on the system.
Only send the ZLP if we send less data than was required/asked for
by the host and it is a multiple of the bMaxPacketSize0 (which is
hardcoded to 8 right now).
This is completing the change done in fe88b83e80 to
fix SIMtrace attached to OSX and not regress on windows.
Introduce another parameter to udp_ep0_send_data to specify the window
size (wLength) or if not available the default from USB 2.0 specification.
- DFU: put all DEBUG_ defines in "#ifdef DEBUG" enclosure
- alter GPIO defines for new OpenPICC v0.4 prototype
- add new AT91F_DBGU_Fini() function
- take care of new inverted USB pullip in OpenPICC v0.4 prototype
- fix typo in 'opicc_reg_write' macro
- add some more PICC related SSC code
NOTE: this firmware is the first version that will _NOT_ run on a OpenPICC v0.3 anymore!

DFU occupies 0x00100000 - 0x00100fff in flash, application starts at 0x00101000.
DFU also occupies the first couple of bytes in SRAM, application starts at 0x00200024.
In order to produce a samba-flashable image, first build dfu.bin by typing
'make -f Makefule.dfu', succeeded by 'make TARGET=... DEBUG=... BOARD=...' and then
concatenating the two files together, e.g. cat dfu.bin main_reqa.bin > flash.bin.
Actual flashing via DFU is still not operational, but will be implemented next
