xserver_xorg-server: Bump version to 1.16.0

xserver_xorg-server: Bump version to 1.16.0

This version bump includes bumping version

xlib_libXfont to 1.4.99.901 & xproto_fontsproto to 2.1.3.

xserver_xorg-server 1.16.0 depends on them, but they are incompatible
with older versions of xserver_xorg-server, for details and libXfont-related
CVE´s see http://lists.x.org/archives/xorg-announce/2014-July/002453.html

Also remove patches applied upstream.

Since a different patch than xserver_xorg-server-100-mips.patch
was committed upstream:
http://cgit.freedesktop.org/xorg/xserver/commit/?id=19e5a13970ad9d440c0789395e94931429ef4fbb
I also compile tested using this defconfig:
