    Add support for selecting pin alternate functions from python. · 6f418fc1

    Converts generted pins to use qstrs instead of string pointers.
    
    This patch also adds the following functions:
    pyb.Pin.names()
    pyb.Pin.af_list()
    pyb.Pin.gpio()
    
    dir(pyb.Pin.board) and dir(pyb.Pin.cpu) also produce useful results.
    
    pyb.Pin now takes kw args.
    
    pyb.Pin.__str__ now prints more useful information about the pin
    configuration.
    
    I found the following functions in my boot.py to be useful:
    ```python
    def pins():
        for pin_name in dir(pyb.Pin.board):
            pin = pyb.Pin(pin_name)
            print('{:10s} {:s}'.format(pin_name, str(pin)))
    
    def af():
        for pin_name in dir(pyb.Pin.board):
            pin = pyb.Pin(pin_name)
            print('{:10s} {:s}'.format(pin_name, str(pin.af_list())))
    ```
