CanvasX11: Check GL version string to ensure that OpenGL(ES) 2.0 is really supported.

When running glmark2 on older hardware (OpenGL 1.x compatible) leads to a
crash. This commit checks that OpenGL(ES) 2.0 is really supported before
trying to execute any OpenGL(ES) 2.0 only code and fails gracefully if it's not
supported (LP #842279).

Android: Use a custom EGLConfigChooser that gracefully handles eglChooseConfig failures.

When proper GLES2.0 drivers are missing from an Android device,
eglChooseConfig() will fail to find a GLES2.0 capable config, as expected.
Unfortunately, the default EGLConfigChooser implementation doesn't give us a
chance to handle this error; it throws an exception that we cannot catch
(because it comes from an internal thread) and crashes the application.

In order to handle the error gracefully, this commit introduces a custom
EGLConfigChooser implementation that in case of error displays an informative
alert and then quits the application.

SceneDesktop: Include cstdlib header file to fix compilation with older compilers.

Older compiler versions are not able to convert int arguments to float in
calls to std::abs() provided by cmath. Include cstdlib header to get the
integer version of std::abs().

Scene,Options: Don't display all the scene options used for benchmarks, unless the user asks for it.

The displayed list of used scene options for each run benchmark can get quite
long and confusing. With this change, only explicitly set options are shown by
default. The user can use the "--show-all-options" command line option to
display all the scene option values used for each run benchmark.
