Resync and correct remove-native
Bump emul-linux-x86 ebuilds to 20140508-r50

So many bumps so little time :-(
Fix a few straglers in the baselibs, gtklibs & medialibs remove-native
files

Also add a temporary soundlibs until the remove-native stops causing
clashes
Think soundlibs has been fixed now
The nine state tracker hasn't been updated in a while

Removing as I've not been testing this
I start removing ebuilds that are already multilib in portage
Fix libdrm dep while I figure out release bump

Current Git master Mesa requires libdrm-2.4.54, but there's no ebuild
for it either in the main Portage tree, nor in x11/FireBurn overlays.
Depend on libdrm-9999 while I investigate whether a rename bump will
work or wait for someone else to do the work for me.
Switch to KeithP's xorg/xserver tree for extra glamor
