Add GPIO device front end with helper functions to provide information
about GPIO Port to Backends and to allow Frontend to set data.
To use it GPIO device should register with qemu_gpio_fe_init()
and provide handlers with qemu_gpio_fe_set_handlers().

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 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

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.

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

Public bug reported:
QEMU seems to support nothing (specific) that 4.4BSD was targeted
to...would be useful to have a complete emulator for a full HP300 to run
the binary dist from McKusick's CD set.
Devices that'd be needed:
* 68020, 68030, or 68040 (How much of these are already present? Not s
