Unwrap after `assert` of transfer length.

Most of the values in the descriptor memory can be modified by the
hardware, so we need to tell Rust that.
Also, refactor the common register setup code into `register.rs`.

Remove let bindings and use `Option.map` instead.

Unfortunate, but necessary for automated testing. Documentation will
need to be added to show usage, and a demo crate.

Don't need special branch anymore.

Simplify the code a bunch to reduce it to states we actually care
about. This will now probe my Logitech G105, NIZ Plum 85EC, and
Keyboard.io Model 01.
* Don't listen for wakeup interrupts. Only listen for device
connection and disconnection, which wakeups sometimes mean.
* Remove the SETTLE_DELAY stuff on device connection, as this
appears to be handled in hardware, and prevents over-delay which
was causing the Model 01 to reset, since it wasn't getting a SOF
in time.
* Set initial max packet size for address 0 endpoint 0 based on
whether the connection is Full Speed or Low Speed.
* Remove all intflag checks from USB handler that we don't
explicitly set up.
* Always listen dor dconn/ddisc in handler. Since we're using a ring
buffer for event storage, we shouldn't miss these and always
handle them in order.
* Don't freeze pipes on errors. Let the hardware do it.
* Don't retransmit packets on errors, just keep polling hardware.
* Move trfail check to the end, since it's either dependent on
previous, more specific checks, or it's just a NAK (but, for some
reason, not ERRORFLOW).
* Add `modify` method to control pipe register.

Get rid of the static mut that can drop intermediate events and cause
innumerable race conditions.

Only use the data toggle from hardware if we get a data toggle
error. Otherwise, use computed toggle values based on endpoint.

This is necessary because atsamd-hal, which this crate uses, needs an
MCU feature selected in order to map peripherals properly.

Since I'm using `make` anyway, might as well consolidate build rules
there.
