f4dfac890f Always call new DoubleBufferedEPOutHandler on reconnect 
Avoid memory leak by deleting the buffers; DoubleBufferedEPOutHandler should be refactored (in beta branch) to allow separate "new" and "setup" procedures

2bb54068a2 Don't reallocate USB buffers if already allocated 
USB Configuration was meant to run only once, but if the board comes back from standby the host can reconfigure the device again.
Probably a cleaner patch could be free()-ing the buffers on standby() to release the memory but at least we don't leak anymore.

9a49ce2fc4 Improve interrupt handling response time 
Change the way ISRs are stored. Store now in a list on a ‘first come
first served basis’, the first interrupt that gets attached will be
served first. This improves the speed of the ISR calling from about 6us
to 2us for a single interrupt on extint14

complete a send will report as failed. If a send times out, a ZLP will
be in the send queue to check for future timeouts.

has been inlined in the callers, this also slightly improves performance
because it allows to remove some redundant checks.

0352cc8558 Change digitalPinToInterrupt to return pin, and use g_APinDescription[pin].ulExtInt to map pin inside attachInterrupt/detachInterrupt 
This brings things inline with the atachInterrupt documentation for
usage:
attachInterrupt(digitalPinToInterrupt(pin), ISR, mode);

0d57cfefe7 Set MANW bit of NVMCTRL to 1 at startup (default is 0). 
This prevents accidental overwrites of the bootloader if a NULL
pointer is used for writing by mistake.
