xorg-3.eclass: Copy from xorg-2.eclass and add EAPI 7 support

Nearly all the work is just removing uses of autotools-multilib and
autotools-utils.

I dropped font support for a couple of reasons:
	1) it's not a small amount of code
	2) font.eclass does not support EAPI 7
	3) none of the fonts packages have changed since the git import

+# This eclass makes trivial X ebuilds possible for apps, drivers,
+# and more. Many things that would normally be done in various functions
+# can be accessed by setting variables instead, such as patching,
+# running eautoreconf, passing options to configure and installing docs.
+#
+# All you need to do in a basic ebuild is inherit this eclass and set
+# DESCRIPTION, KEYWORDS and RDEPEND/DEPEND. If your package is hosted
+# with the other X packages, you don't need to set SRC_URI. Pretty much
+# everything else should be automatic.
