Add GUSE (FUSE based kernel module similiar to CUSE) based backend.
This allows transparent usage of Linux GPIO UAPI based tools like
in kernel tools/gpio or libgpiod.
libgpiod requires some modification to allow "/sys/class/guse" in
gpiod_check_gpiochip_device().
It requir
While vhost-user-gpio-pci is a good solution to pass gpios inside guest
it still doesn't cover the following cases:
- AFAIK the board needs to have a PCI bus;
- we add new hot-plugged gpios instead of re-using the existing ones;
- we can't connect it to existing gpio models;
This functionality is

Add gpiodev support for:
- getting line info
- getting/setting lines
- monitoring line events
- monitoting config events
Binding is done via id, i.e.:
... -gpiodev chardev,id=aspeed-gpio0

Currently based on passing linux GPIO UAPI structs over
UNIX socket.
This is more a PoC than a real application, still this is something to
start with.
