[FFe] Enable Mir video support for 2.0.2

[Brandon Schaefer]

By default Mir support is turned off. Enable it by default.

The code is isolated and will not affect other platforms running SDL2. It will only provide support for Mir. This will be helpful with unity8 to have Mir support on by default. Allowing support for SDL2 apps on unity8 automatically just by enabling this flag.

Changelog:

libsdl2 (2.0.2+dfsg1-3ubuntu1) trusty; urgency=medium

  * Enable Mir video support. [linux-any]

Built successfully on 14.04, as well as ensured Mir support was enabled when configure was going off. Installed over the new lisdl2.0.2 that was just sync earlier today bug 1293043.

From there I used my own test application [1] that is an SDL2 app. With this minor change, it now works directly on mir/unity8. As well as tested each test program that lives inside SDL2/tests/.

I see that the MP review has gone through a couple rounds of feedback, and the latest patch looks solid.

This will introduce a new dependency from the libsdl2-2.0-0 package on libmirclient. Since both packages are in main, and neither package is seeded on any images, this is ok.

FFe granted.

This bug was fixed in the package libsdl2 - 2.0.2+dfsg1-3ubuntu1

I believe something is wrong with MIR support. A daily build of openmw just failed with:
/usr/include/SDL2/SDL_syswm.h:97:44: fatal error: mir_toolkit/mir_client_library.h: No such file or directory
 #include <mir_toolkit/mir_client_library.h>

In SDL_syswm.h:
#if defined(SDL_VIDEO_DRIVER_MIR)
#include <mir_toolkit/mir_client_library.h>
#endif

the file is:
/usr/include/mirclient/mir_toolkit/mir_client_library.h

it built successfully until this libsdl2 commit hit that enabled mir
