Subject: Migrate everything over to separate libraries.

  * `usb-host` is the crate containing the HAL traits.

  * `bootkbd` is a crate for a bare-bones boot protocol keyboard
    driver.

  * `samd21-host` is a crate with an implementation of `usb-host` for
    a SAMD21 platform, with an example for the trinket-m0 which uses
    the `bootkbd` driver to print keyboard reports.
