Failing to check if a key was known to be pressed by SDL was causing
SDL_SendKeyboardKey to send duplicate key pressed events with the repeat
property set to true.
Fixes Bugzilla #3637.
The message sent upon the window being activated or deactivated, to trigger
the call to SDL_SetKeyboardFocus was missing a mandatory parameter. So
keyboard focus was never properly set.
Fixes Bugzilla #3658.
We don't fill buffers just to throw them away during shutdown now, we let the
AudioQueue free its own buffers during disposal (which fixes possible warnings
getting printed to stderr by CoreAudio), and we stop the queue after running
any queued audio during shutdown, which prevents dropping the end of the
audio playback if you opened the device with an enormous sample buffer.
Fixes Bugzilla #3555.
We need more than two buffers to flip between if they are small, or CoreAudio
won't make any sound; apparently it needs X milliseconds of audio queued when
it needs to play more or it drops any queued buffers. We are currently
guessing 50 milliseconds as a minimum, but there's probably a more proper
way to get the minimum time period from the system.

"Starting with Android API 13, another configuration change must be declared
to be handled by the app if it is desired to not let the system handle
rotation itself:
https://developer.android.com/guide/topics/resources/runtime-changes.html#HandlingTheChange
This will have effect if either a developer or SDL per default will set target
API > 12. Currently it is set to 12, but this might change in the future, like
when applying this patch: https://bugzilla.libsdl.org/show_bug.cgi?id=3445
The effect of not having this change applied is that the SDL app is destroyed
upon rotation. Even when the manifest has an additional entry to e.g. always
stay in landscape mode, the onDestroy() call will happen on devices that are
portrait per default, when switching off screen due to power save. The device
will then (at least try to) rotate into portrait to show the portrait screen
lock after resume.
I believe it is safe to apply this patch even with target API still set to 12,
the additional parameter is simply ignored."
