Allow the control device to implement things such as flushing the
command buffer as part of the close operation. This used to be done to
ensure that any lingering power/usb off requests really where sent to
the device as we closed the control tty.

As cdba-server exits it turns off power, which used to cut VBUS as well,
but since the refactoring only cuts power. Reintroduce the VBUS toggle
to ensure the device doesn't stay powered through USB after use.

The power key dance is useful outside of alpaca, move it to device and
modify the device interface to better suite this.

Squash the power_on and power_off into a single "power" function, to
harmonize the code wrt the USB handling.

Some ancient device needed us to pull PSHOLD to trigger the shutdown,
but most of the code is lost, so clean out the last pieces until the
need comes up again.

All modern systems will properly populate /dev/serial/by-id with links
to the CDB Assist control and target tty, that includes the serial
number in the name.
So there's no reason to keep the complex code that scans for the two
devices by serial number around.
Switch the parameter of "cdb_assist" to be the path of the control tty
and rely on "console" for the "terminal" tty.
Naturally this breaks existing config files.

By renaming the "alpaca_dev" to "control_dev" is can be reused in the
other implementations as well.

USB on the Primus acts up when we toggle USB in Alpaca, so add a
configuration option to force it on at all times.

Make the fastboot key handling a property of the device configuration
and use the newly introduced timeout mechanism for handling it.

Add a new keyword "description" to the config file, add the necessary
wire protocol to acquire this string for a given device and introduce
the "-i" option to cdba to trigger its retrieval.

Add a new argument '-l' which in combination with '-h' will connect to
said server and list the attached devices, then exit.

It's possible for devices that are automated using e.g. a CDB Assist to
have console coming over a separate FTDI USB tty. Move the alpaca
specific implementation of the "console" directive to device.c to make
it generic.

For some devices it's not possible to use fastboot boot and
as such they will not enter fastboot unless the fastboot key
is held. Expose this functionality in the device api.

In order to support multiple control boards make all operations follow
indirections in the device context.
