Fixed crash if initialization of EGL failed but was tried again later.

Browse Source 
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().

Support for Wayland with QmlCompositor as Server
================================================
The Wayland video driver has support for some additional features when
using QtWayland's "qmlcompositor" as Wayland server. This is needed for touch
input when running SDL applications under a qmlcompositor Wayland server.
The files following headers have been
generated from the Wayland XML Protocol Definition in QtWayland as follows:
Clone QtWayland from Git:
http://qt.gitorious.org/qt/qtwayland/
Generate headers and glue code:
for extension in touch-extension surface-extension windowmanager; do
wayland-scanner client-header < src/extensions/$extension.xml > wayland-qt-$extension.h
wayland-scanner code < src/extensions/$extension.xml > wayland-qt-$extension.c
