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

5265e1215a USB: EP0 ::recv method has been merged with ::read method 
It makes no sense to have ::recv calling repeatedly ::read in this
case.

a9127228d6 USB: Slightly refactored EP OUT handler 
Now the release() function only performs the action that is called for,
i.e. release the endpoint and let it receive data. All the buffers handling
has been inlined in the callers, this also slightly improves performance
because it allows to remove some redundant checks.

ac16594d2a Disabled SRAM shortcut when in USBCore::send 
The shortcut has some issues:

- sometimes it fails when sending an odd number of bytes (may be
  due to memory alignment?)
- the data pointer should point to "stable" data (and this is not
  guaranteed by caller, it may be some sort of temporary buffer)
- the SRAM is not guaranteed to start at 0x20000000

All the above problems must be properly fixed before reenabling
this part
