If copyin() fails, the driver will proceed blindly with a zeroed buffer,
which is not what we want. In preparation for annotating copyin() with
__result_use_check, start checking for errors.

In commit c77bfaa750 uhid(4) gained support for ioctl from
USB_GET_DEVICEINFO. This is used in libraries like libfido2 to
retrieve information about a device.
This commit adds binary compatible version to hidraw(4).

Make HIDIOCGRAWPHYS, HIDIOCGRAWNAME, and HIDIOCGRAWUNIQ return
the length of the copied out string (including the trailing NUL
character), so they behave like their Linux hidraw counterparts.

Use thunks or alternative access methods to support ioctls without
the COMPAT_32BIT hacks that store pointers in uint64_t's on 32-bit
platforms. This should allow a normal i386 libusb to work.
On CheriBSD, the sizes of the structs will differ between CheriABI
(the default) and freebsd64 no matter what so we need proper compat
support there. This change paves the way.

As side effect it renames traditional uhid(4) driver to hidraw

This driver provides raw access to HID devices through uhid(4)-compatible
interface and is based on pre-8.x uhid(4) code. Unlike uhid(4) it does
not take devices in to monopoly ownership and allows parallel access
from other drivers.
hidraw supports Linux's hidraw-compatible interface as well.
