Allow "n"/"m"/"y" as aliases for 0/1/2 in set_value()

More experience working with the API convinced me that it's worth it.
Gets rid of ugly conversions in the menuconfig.py and oldconfig.py
examples, and streamlines some things internally as well.

Include two other small fixes as well:

  - Make warnings generated by Choice.set_value() match those generated
    by Symbol.set_value().

  - Get rid of the input stripping in menuconfig.py. It's not like the
    interface is usable as-is anyway, and it just complicates the
    example.
