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.

Introduce some scripts to allow storing users public keys in a git and
some hooks such that when this is pushed to the server the
authorized_keys file is re-generated.

Transfering the image to cdba server takes time (especially when working
with over the network). Notify users before actually booting the board
to ease detecting early boot issues.

Opening the lock files fails on one of my boards if the files exists and
are owned by someone else, if O_CREAT is set. This doesn't make sense,
but hack around it for now by first creating the file if it's not there,
ignoring any errors and then just opening it O_RDONLY.

For debug purposes it's useful to install a user-local version of the
cdba-server and invoke this instead, rather then having to change the
code add a flag to support specifying this on the command line.

For some reason the SC8180x Primus often fails to detect the attached
USB stick if USB is toggled as part of a power cycle, so let's continue
to support the property of not toggling it.

In the case that we quit without actually having opened a device this
would dereference a NULL pointer, so check the device before doing so.

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 fastboot_key function is no longer used, drop the remains in the

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

Squash the power_on and power_off into a single "power" function, to

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

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
