This was the only API that broke the "GetNumThings" convention
used elsewhere, so renaming it helps with consistency.
Adding "logical cores" to the name also makes it a bit
more immediately obvious what the count actually represents.
This had the unfortunate side-effect of blocking if you tried to write too much. Instead you can use SDL_GetProcessInput() and handle SDL_IO_STATUS_NOT_READY as needed.

Also marked the existing functions as unsafe, as they can cause crashes if used in multi-threaded applications.
As a bonus, since the new functions are hashtable based, hint environment lookups are much faster.
Also added SDL_PROP_IOSTREAM_FILE_DESCRIPTOR_NUMBER and refactored the internal API to be able to create SDL_IOStream objects from native file handles.
Allow setting a parent/child relationship on toplevel windows, which allows raising sets of windows together, and allows child windows to always float above their parents.
Modal windows are now set by setting the parent, then toggling modal status, as the previous interface duplicated functionality now handled by SDL_SetWindowParent().
This changes the API in various ways, and updates the backends for this.
Overall, this is a massive simplification of the API, as most future backends
can't support the previously-offered API.
This also removes the testautomation pen code (not only did these interfaces
change completely, it also did something no other test did: mock the internal
API), and replaces testpen.c with a different implementation (the existing
code was fine, it was just easier to start from scratch than update it).
This adds functions to query the keymap:
* SDL_GetCurrentKeymap()
* SDL_GetKeymapKeycode()
* SDL_GetKeymapScancode()
* SDL_ReleaseKeymap()
and these are distinct from the function to query the event keycode associated with a scancode, which might be affected by SDL_HINT_KEYCODE_OPTIONS.
Also added an SDL_bool parameter to SDL_GetKeyName() and SDL_GetKeyFromName() to enable upper case handling of the name.
SDL_Log() no longer prints a log prefix by default for SDL_LOG_PRIORITY_INFO and below. The log prefixes can be customized with SDL_SetLogPriorityPrefix().
Removed duplicate hints SDL_HINT_APP_NAME, SDL_HINT_APP_ID, and
SDL_HINT_AUDIO_DEVICE_APP_NAME.
Wired up a few things to use the metadata; more to come!

This was just causing confusion and anxiety. SDL temporary memory will be automatically freed on the main thread when processing events and on other threads when it ages out after a second. The application can free it directly by calling SDL_ClaimTemporaryMemory() to get ownership of the pointer, if necessary.
SDL_BlitSurfaceScaled() is more flexible and uses the SDL_SoftStretch() fast path when possible. Having two surface scaling APIs was confusing, especially when one of them has unexpected limitations.
