Regenerate all distfiles using gitlab as source.

This regeneration is required as the new gitlab version changed
the address and the directory the source files can be downloaded.

This commit also applies some small fixes to make sure all ports using
gitlab are buildable.

devel/libevdev: Update to teh lastest snapshot

Update devel/libevdev to the latest snapshot.
This snapshot is comparable to libevdev 1.9.1 with added FreeBSD support and
some minor fixes.
Remove local patches for FreeBSD support, as FreeBSD support has been
developed and committed upstream.
Switch to use meson instead of autotools for builds
Use bundled files instead of evdev-proto, similar to how x11/libinput is
done.
Pass maintainership to x11@, since this port is used in the xorg and wayland
input stack.

Bump portrevision for devel/evdev-proto

Bump portrevision on everything with a build dependency on
devel/evdev-proto, to chace the update of evdev-proto in r550442.

devel/evdev-proto: Update to 5.3

There are currently 3 copies of joystick.h in the ports tree with
more on the way.  Provide it in evdev-proto instead to avoid adding
more copies and to allow removing the existing ones.

devel/libevdev: Drop unhooked TEST_USES helper

USES=pkgconfig is always in USES anyway.

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.

devel/libevdev: drop unused pkgconfig build dependency

pkg-config is only needed to detect libcheck used to build tests.
Running tests requires /dev/uinput which is only implemented by
evdev(4) from GSoC2014 but not webcamd.

devel/libevdev: add new port

PR:		196978
Submitted by:	hselasky

libevdev is a wrapper library for evdev devices. It moves the common
tasks when dealing with evdev devices into a library and provides a
library interface to the callers, thus avoiding erroneous ioctls, etc.

The eventual goal is that libevdev wraps all ioctls available to evdev
devices, thus making direct access unnecessary.
