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().

emscripten: send fake mouse events for touches, like other targets do. (This really should be handled at the higher level and not in the individual targets, but this fixes the immediate bug.)

emscripten: keep track of pointer lock losses and maybe regrab pointer later. If an Emscripten app is in relative mouse mode and the user presses Escape (or whatever is appropriate), then the pointer lock is broken by the browser. This keeps track of those losses, and next time the user presses a mouse button down on the canvas, if the app is still meant to be in relative mouse mode, we will attempt to regrab the pointer. This makes it much more seamless for things like first-person shooters, and the app doesn't need any manual intervention.
