hidraw(4): Add additional hidraw input/output report ioctls

to Linux hidraw compatibility API.

Respective Linux commit f43d3870cafa made by Dean Camera message is:

Currently the hidraw module can only read and write feature HID reports on
demand, via dedicated ioctls. Input reports are read from the device through
the read() interface, while output reports are written through the write
interface().

This is insufficient; it is desirable in many situations to be able to read and
write input and output reports through the control interface to cover
additional scenarios:

- Reading an input report by its report ID, to get initial state
- Writing an input report, to set initial input state in the device
- Reading an output report by its report ID, to obtain current state
- Writing an output report by its report ID, out of band

This patch adds these missing ioctl requests to read and write the remaining
HID report types. Note that not all HID backends will neccesarily support this
(e.g. while the USB link layer supports setting Input reports, others may not).

FreeBSD native uhid(4) compatible API already has similar ioctls.

Now that we have proper 32-bit compat support, remove COMPAT_32BIT
ifdefs to allow 32-bit code to use the 64-bit layout of USB ioctl

This includes the removal of redundant alignment directives that had
no effect in practice.

usb: add 32-bit compat for FIFOs

Unlike most 32-bit compatability code, this isn't just a simple thunk
in the ioctl code. An ioctl (USB_FS_INIT) is used to install a
pointer to an array of usb_fs_endpoint structs which are then used
by the ugen fifo code. These struct contains an array of pointers
which requires translation. We change the interfaces around
struct usb_fs_endpoint as follows:
- We store the size of struct usb_fs_endpoint in struct usb_fifo
in the USB_FS_INIT handler so we know the ABI of the userspace
array.
- APIs to manipulate userspace struct usb_fs_endpoint objects now
take a struct usb_fifo and an index rather than a pointer to
the object. This allows most code to remain oblivious to the
different struct usb_fs_endpoint sizes.
- Add ugen_fs_copyin() which copies the struct usb_fs_endpoint
from userspace, thunking it to the native size if required.
- Uses of struct usb_fs_endpoint's ppBuffer member are now
via ugen_fs_getbuffer() which produces a native pointer.
- Updates to userspace are now handled by ugen_fs_update().

For clarity, single, fixed-sized members now are accessed with
fueword/suword rather than copyin/copyout.

usb: real freebsd32 support for most ioctls

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.

sys/dev: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
