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().

threads: Move SDL's own thread creation to a new internal API. This allows us to set an explicit stack size (overriding the system default and the global hint an app might have set), and remove all the macro salsa for dealing with _beginthreadex and such, as internal threads always set those to NULL anyhow. I've taken some guesses on reasonable (and tiny!) stack sizes for our internal threads, but some of these might turn out to be too small in practice and need an increase. Most of them are simple functions, though.
