Largely inspired from hid_bpf.c for the fixture setup.
Create a couple of tests for hidraw:
- create a uhid device and check if the fixture is working properly
- inject one uhid event and read it through hidraw
These tests are not that useful for now, but will be once we start adding
the ioctl and BPFs to revoke the hidraw node.

When adding new tests programs, we need the same mechanics to create
new virtual devices, and read from their matching hidraw node.
Extract the common part into its own header so we can easily add new
tests C-files.

There is a need for userspace applications to open HID devices directly.
Use-cases include configuration of gaming mice or direct access to
joystick devices. The latter is currently handled by the uaccess tag in
systemd, other devices include more custom/local configurations or just
sudo.
A better approach is what we already have for evdev devices: give the
application a file descriptor and revoke it when it may no longer access
that device.
This patch is the hidraw equivalent to the EVIOCREVOKE ioctl, see
commit c7dc65737c9a ("Input: evdev - add EVIOCREVOKE ioctl") for full
details.

By allowing the drivers to return a "const *" they can constify their
static report arrays.
This makes it clear to driver authors that the HID core will not modify
those reports and they can be reused for multiple devices.
Furthermore security is slightly improved as those reports are protected
against accidental or malicious modifications.

fuse_notify_store(), unlike fuse_do_readpage(), does not enable page
zeroing (because it can be used to change partial page contents).
So fuse_notify_store() must be more careful to fully initialize page
contents (including parts of the page that are beyond end-of-file)
before marking the page uptodate.
The current code can leave beyond-EOF page contents uninitialized, which
makes these uninitialized page contents visible to userspace via mmap().
This is an information leak, but only affects systems which do not
enable init-on-alloc (via CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y or the
corresponding kernel command line parameter).
