fa6292118d Major refactor of USB CCID and USB HID interfaces. All interfaces are rewritten. 
With this new scheme we ensure that:
- memcpy's are reduced.
- no race conditions are performed.
- critical areas are protected.
- callbacks are executed immediately.
- write's are executed after the positive report is received.
- no usb middle interface anymore.
- CCID and HID are totally independent.

11447371fe Rewritten continuous flow for HID. 
HID uses complete_cb to send the next packet and not the value returned by tud_write. Therefore, no other writes can happen in between of a writing packet if fails.

This ensures a proper interface multiplexing and continuous flow.

Also, the read pointer is used to multiplex usb packets.

4919eb980f Added a major refactoring to include Emulated interface. 
It works in combination with virtualsmarcard module (vpcd). It properly installed, it creates a virtual reader that can be interfaced via PCSC+vcpd. At user app level, it has no difference of having a physical smart card.

At this moment, it only works emulating a CCID interface.

4a8a6728c7 Adding support for specific vendor HID command (0x41). 
It is a self implementation, based on CBOR command.
data[0] conveys the command and the contents mapped in CBOR encoding.
The map uses the authConfig template, where the fist item in the map is the subcommand (enable/disable at this moment), the second is a map of the parameters, the third and fourth are the pinUvParam and pinUvProtocol.

With this format only a single vendor HID command is necessary (0x41), which will be used for all my own commands, by using the command id in data[0] like with CBOR.
