Separate backend operations into control and console operations. Main
idea is that each device has single set of console ops (conmux or
console) and at most one way to control it. Each backend driver exports
a structure with the set of callbacks.

Allow PPPS function even if there is no device->usb callback. PPPS is

Since Linux kernel 6.0, PPPS capable USB hubs expose a simple sysfs
attribute for power control. Allow overwriting the usb control callback
to use PPPS hub control instead.

Limit access control to the boards according to the passed username. If
the user has no access, the board becoms completely invisible: it is not
listed, it is not possible to fetch board description, etc.

For different reasons it might be desirable to keep slot 'b' as an
active slot. Add support for specifying the active slot in the config
file. The default is still slot 'a'.

Code should avoid comparing signed and unsigned integers, because of
implicit case. Explicit casts are safe because 'lock' size is PATH_MAX.
device.c: In function ‘device_lock’:
device.c:64:15: warning: comparison of integer expressions of different signedness: ‘int’ and ‘long unsigned int’ [-Wsign-compare]

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 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.

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.

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.
