In order to sleep for fractions of a second in alpaca, change the
timeout from seconds to milliseconds.

There are cases where holding the fastboot key for too long will cause
the attached device to reset. So rather than holding the fastboot key
until fastboot arrives use the newly introduced common fastboot
handling.

In the event that the system contains ACM devices that are not CDB
Assist these won't be either control nor target devices. So don't err
out on this.

The generic device code will now request toggling of the fastboot key
based on the device's configuration, so remove the hard coded
invocation.

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

It's useful to be able to invoke some operation in the future, such as
releasing a key. Add support for registering and executing callbacks in
the future.

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.

If fastboot device is already present when starting cdba, cdba may miss
it. So enumerate usb devices via libudev to look for fastboot device
node.

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.

Rather than hard coding the server side path to
sandbox/cdba/cdba-server, just invoke cdba-server and rely on the server
side to have the tool in $PATH.

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

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

Receiving an invalid command should lead to termination of the client,
but doing so abruptly will cause the termios not to be reset.

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.

With tty_open() moved from cbd_assist to a common place we can use this
for the alpaca implementation as well.

The cdb_assist implementation of tty_open() can be reused by other
files, so let's move it to cdba-server.c.

SERVER better reflects its current role and reflects the rename of the
