Now x11-packages repository will use original names for
packages. For example, libgtk2 now will be provided as
gtk2, libgtk3 will be available as gtk3, libsdl - as sdl.
List of changed packages:
libatk --> atk
libglu --> glu
libgtk2 --> gtk2
libgtk3 --> gtk3
libmesa --> mesa
libsdl --> sdl
libsdl2 --> sdl2
libsdl-net --> sdl-net
riscvemu-sdl --> riscvemu
xorg-xvfb --> xorg-server-xvfb
List of dependent packages (should be rebuilt with new deps):
dosbox, emacs-x, galculator, geany, libepoxy, mtpaint,
qemu-system-x86_64, the-powder-toy, tigervnc, wireshark-gtk,
xarchiver.
Note: depending on which packages are installed, it may be
necessary to upgrade with 'apt dist-upgrade'.
Fixes issues with stale lock files in case Xvnc was killed.
Note: original implementation of locking uses link(2) which is
disallowed by seccomp on Android 8 or later.
