This permits driving a board controlled by GPIOs on an FTDI
interface.
Also add a sample 99-libftdi.rules to permit using the FTDI device.

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.

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.

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.

It seems more suitable to use the "control_dev" to denote the target
conmux than "cdb_serial". Further more this makes it possible drop the
"cdb_serial" member in an upcoming commit.

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 device power controller optional, allowing one to use cdba in
non-automated setup (just simplifying the fastboot + console handling).

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

For some devices to reliably boot into fastboot mode volume down needs
to be held, so do this as we power on the device and release it as
fastboot appears.

The error message indicating that cdba-server failed to open the config
file was supposed to be moved to cdba-server.c, but I forgot to remove
the error from the device_parser. Fix this.

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.

After attempting to read .cdba, fall back to read /etc/cdba - to make it
possible to provide system wide configuration for a multiple users.

accept() expects the passed "scalar" to be 256 bytes long, so passing
the 80 char key will cause an out-of-range write.

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.

When pointing alpaca to persistent named aliases in /dev/serial/by-id we
end up with > 80 chars of path in value, which gets nicely truncated.
Increase this max.

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.
