* Avoid unnecessary SDL_PumpEvents calls in SDL_WaitEventTimeout
* Add a sentinel event to avoid infinite poll loops
* Move SDL_POLLSENTINEL to new internal event category
* Tweak documentation to indicate SDL_PumpEvents isn't always called
* Avoid shadowing event variable
* Ignore poll sentinel if more (user) events have been added after

This is needed to support CHERI, and thus Arm's experimental Morello
prototype, where pointers are implemented using unforgeable capabilities
that include bounds and permissions metadata to provide fine-grained
spatial and referential memory safety, as well as revocation by sweeping
memory to provide heap temporal memory safety.
Added support for the PS4 controller gyro and accelerometer on iOS and HIDAPI drivers
Also fixed an issue with the accelerometer on iOS having inverted axes

The event timestamp members should be documented to indicate their meaning and units.
Currently the timestamps are populated using SDL_GetTicks() in SDL_PushEvent() in SDL_events.c.
This allows an app to know when a set of drops are coming in a grouping of
some sort (for example, a user selected multiple files and dropped them all
on the window with a single drag), and when that set is complete.
This also adds a window ID to the drop events, so the app can determine to
which window a given drop was delivered. For application-level drops (for
example, you launched an app by dropping a file on its icon), the window ID
will be zero.
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().
