Ladi Prosek b065e275a8 virtio-input: support absolute axis config in pass-through
VIRTIO_INPUT_CFG_ABS_INFO was not implemented for pass-through input
devices. This patch follows the existing design and pre-fetches the
config for all absolute axes using EVIOCGABS at realize time.

Ladi Prosek 1a782629f6 virtio-input: implement pass-through evdev writes
The write path for pass-through devices, commonly used for controlling
keyboard LEDs via EV_LED, was not implemented. This commit adds the
necessary plumbing to connect the status virtio queue to the host evdev
file descriptor.

Ladi Prosek 848c4d4480 virtio-input: retrieve EV_LED host config bits

returning an empty bitmap for pass-through input devices.

Markus Armbruster da34e65cb4 include/qemu/osdep.h: Don't include qapi/error.h
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef.  Since then, we've moved to include qemu/osdep.h
everywhere.  Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h.  That's in excess of
100KiB of crap most .c files don't actually need.

Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h.  Include qapi/error.h in .c files that need it and don't
get it now.  Include qapi-types.h in qom/object.h for uint16List.

Update scripts/clean-includes accordingly.  Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h.  Update the list of includes in the qemu/osdep.h
comment quoted above similarly.

This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third.  Unfortunately, the number depending on
qapi-types.h shrinks only a little.  More work is needed for that one.

Peter Maydell 9b8bfe21be virtio: Clean up includes
Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

This commit was created with scripts/clean-includes.

Gerd Hoffmann e2f6bac301 virtio-input: move sys/ioctl.h include
Drop from include/standard-headers/linux/input.h
Add to hw/input/virtio-input-host.c instead.

That allows to build virtio-input (except pass-through) on windows.

Gerd Hoffmann 006a5edebe virtio-input: evdev passthrough
This allows to assign host input devices to the guest:

qemu -device virtio-input-host-pci,evdev=/dev/input/event<nr>

The guest gets exclusive access to the input device, so be careful
with assigning the keyboard if you have only one connected to your
machine.
