This patch series adds a registry for user interfaces (aka displays),
adds support for user interface modules and allows to build sdl, gtk
and curses as modules.  Especially gtk cuts down the number of shared
libraries qemu links against by a significant amount.

Note one: Modules are disabled by default, so configure with
          --enable-modules to test this.

Note two: Qemu build system doesn't rebuild object files when
          the compiler flags change.  You might see build failures
	  when enabling modules without "make clean" because of this,
          due to non-modular object files being built without -fPIC.

Gerd Hoffmann (12):
  console: add qemu display registry, add gtk
  sdl: switch over to new display registry
  cocoa: switch over to new display registry
  curses: switch over to new display registry
  egl-headless: switch over to new display registry
  console: add and use qemu_display_find_default
  console: add ui module loading support
  configure: add X11 vars to config-host.mak
  configure: opengl doesn't depend on x11
  sdl: build as ui module
  gtk: build as ui module
  curses: build as ui module
