Bumped copyright date on Mir code.
Add Mir to configure script's summary output.
Hooked up dynamic loading for Mir.
Unload Wayland libs if memory allocation fails during init.
Temporarily default Wayland and Mir to disabled, for 2.0.2 release.

We'll flip the default back to enabled right after 2.0.2 is finalized, and
try to declare them stable and ready by 2.0.3.

Those that have an interest in supporting them in 2.0.2 can manually enable
 them in the configure script with --enable-video-wayland and/or
 --enable-video-mir.
