Split out evdev headers from multimedia/v4l_compat
Split out evdev headers (input.h, input-event-codes.h, uinput.h) into their
own port, devel/evdev-proto, and update those to be current with the Linux
4.19 kernel. This is done in order to be able to update the rest of the
FreeBSD input stack, which is forthcoming.
By splititng out the evdev headers we can update them independent of other
updates in v4l_compat, which makes it easier for the graphics team to keep
track of them and keep them updated as needed.
Update devel/libevdev from 1.4.4 to 1.5.9 instead of trying to make it work
with the updated headers. This will be further updated.
Update devel/py-evdev from 0.5.0 to 0.8.1 instead of trying to make it work(Only the first 15 lines of the commit message are shown above )
