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

Add and update include guards Include guards in most changed files were missing, I added them keeping the same style as other SDL files. In some cases I moved the include guards around to be the first thing the header has to take advantage of any possible improvements compiler may have for inclusion guards.
