FreshBSD

   fix merge botches.

   re-add files autoconf files that the build sort of needs at
   least configure for.  command used:

     % cd /usr/xsrc/external/mit/xf86-video-intel/dist
     % autoreconf -I m4 -I /usr/xsrc/external/mit/xorg-server/dist -i

   tested on sandy bridge and kaby lake.

   merge xf86-video-intel 6afed33b2d673d88674f0c76efe500ae414e8e1b.

   initial import of xf86-video-intel git version 6afed33b2d673d88674f0c76efe500ae414e8e1b

   merge libXvMC 1.0.11, libXxf86dga 1.1.5, libxkbfile 1.1.0, and xtrans 1.4.0.

   initial import of xtrans-1.4.0

   merge changes from xorg-server 1.20 list.h into this older version.

   fixes sandy bridge crashing problems for me.

   spell it defined(__NetBSD__) so it actually matches and we skip this
   pragma warning during the build:

   Warning: Per application configuration won't work with your OS version.

   remove files not wanted for mesa 18.

   remove reference to non existance sys.startxrc.

   restore change lost in Xservers.ws.cpp -> Xservers.ws.in rename:

   http://mail-index.netbsd.org/source-changes/2012/02/18/msg031930.html

   Add -noretro as default server arg in configuration files where we are
   sure the user will get a visible window "soon".
   The sole reason we backed out the "retro" change from upstream
   was to avoid an empty black screen after manualy starting just "X". With
   these preconfigured startup mehtods, this confusion can not happen.

       Don't warn (-Werror) about secure_getenv, use getenv_wrapper.

       Does the same thing for netbsd.

       Make GCC happier about prototype, include right header for __HAVE_ATOMIC64_OPS

   commit 93c2f416aa316cc3d0665661c9f927f6949cdd37
   Author: coypu <coypu at sdf.org>
   Date:   Mon Mar 4 12:16:56 2019 +0200

       Make the u_atomic.c fallback locked 64bit atomics more suited

       for the netbsd case: we are using __GNUC__ compilers, but without
       libatomic. so we are emitting the __GNUC__ names.

       Use __HAVE_ATOMIC64_OPS which is the netbsd name for this condition
       (we don't run configure)

   Initial revision

   from maya:

   Import mesa 18.3.4.

   Mesa 18.3.4 implements the OpenGL 4.5 API.
   Some drivers don't support all the features required in OpenGL 4.5.

   initial import of libvdpau-1.1.1

   fix merge botch in previous.

   Initial revision

   merge xf86-video-amdgpu 19.0.0.

   initial import of xf86-video-amdgpu-19.0.0

   turn on execinfo support.

   regen for fontconfig 2.13.1.

   merge fontconfig 2.13.1.

   initial import of fontconfig-2.13.1

   remove some unnecessary code:
   - win32
   - other comapt code
   - uuid daemon code
   - TLS code
   - unused functions and features

   import a small portion of util-linux's "libuuid".  this is needed for
   the new fontconfig which uses these APIs internally.  we'll rename
   the symbols and they aren't exported by fontconfig.so anyway.

   this is necessary because libuuid's API conflicts with netbsd libc
   uuid API while being not really simple to shim or provide compat for.
