Paul Sokolovsky 751e3b7a82 extmod/virtpin: Initial implementation of open-ended C-level Pin interface. ...

Using usual method of virtual method tables. Single virtual method,
ioctl, is defined currently for all operations. This universal and
extensible vtable-based method is also defined as a default MPHAL
GPIO implementation, but a specific port may override it with its
own implementation (e.g. close-ended, but very efficient, e.g. avoiding
virtual method dispatch).
