graphics/mesa: Fix minor issues from meson switch

Fix a couple of minor issues with mesa related ports after the switch to
meson.
Define _GNU_SOURCE when building on FreeBSD.  This fixes blur effects in
Plasma 5 and issues with the SDDM greeter.  This fix was originally applied
in r516100 but got lost in the switch to meson. [1]
Properly detect sys/sysctl.h on FreeBSD.  On FreeBSD sys/sysctl.h needs
sys/types.h as well, patch the meson build script to take this into account.
Fix a broken sed command to properly set ${LOCALBASE}/etc and
${LOCALBASE}/share/ as appropriate.

Bump portrevision of all mesa related ports.

mesa: Fix build empty DRI_DRIVER

In some cases, such as on sparc64, armv6 and armv7 etc, DRI_DRIVER,
GALLIUM_DRIVER and/or VULKAN_DRIVER might be undefined.  This causes an
error similar to
make: "/usr/ports/graphics/mesa-dri/Makefile" line 106: Malformed conditional
(${DRI_DRIVERS:M${:UI915}})

Fix this by checking if [DRI,GALLIUM,VULKAN]_DRIVER is defined before
checking what it is set to.

While here, remove textproc/py-mako dependency from mesa-dri/Makefile, it's
already included in mesa-dri/Makefile.common, no need to depend on it twice.

 mesa*: Add platforms option

Keep the WAYLAND option for now but if you're using it switch to the
newly created PLATFORM_WAYLAND.

mesa*: Switch to meson

Upstream switched to meson for their build system so do the same as
it will be easier to find problems sooner than later.
This also switch to python3, python is only used for the build.
There is more thing enabled by default (or auto-enabled based on some
configuration) so we need to disable a lot more things than with autotools.

This should be a non functional change.

graphics/libglvnd: add new port

Submitted by:	Greg V <greg@unrelenting.technology>

libglvnd is a vendor-neutral dispatch layer for arbitrating OpenGL API calls
between multiple vendors. It allows multiple drivers from different vendors to
coexist on the same filesystem, and determines which vendor to dispatch each
API call to at runtime.

Both GLX and EGL are supported, in any combination with OpenGL and OpenGL ES.

graphics/mesa: Update to 19.0.8

build system and to enable further updates.

graphics/mesa-libs: fix build on powerpc head

Clang currently lacks atomic functions on powerpc, making build fail:
u_atomic.c:64:1: error: definition of builtin function
'__sync_val_compare_and_swap_8'

Use GCC for now.

graphics/mesa-libs: Change default to use DRI3

Change the default mesa configuration to use DRI3 rather than the older DRI2
interface.  This should improve performance somewhat, and alleviates the need
for the FIXDRM option in x11-servers/xorg-server.

Remove the FIXDRM option from x11-servers/xorg-server.

Add an UPDATING entry for the change.

For users of graphics/drm-legacy-kmod or the base graphics drivers, this might
cause regressions.  If you experience problems when running OpenGL applications
please force the use of the DRI2 backend by setting the LIBGL_DRI3_DISABLE
environment variable to 1 before starting any OpenGL application.  This is
easiest done by adding it to your shell startup file or .xinitrc.

Add UPDATING entry for xorg-server, detailing the change of device
configuration backend.
