LINUX_JoystickInit does a manual scan first so devices are sorted.
If SDL_UDEV_Init hasn't run by then, then the product info cannot
be looked up by SDL_UDEV_GetProductInfo and the initial-plugged-
in-device classification falls back to heuristic guessing.

Replacing function call `kill(0, SIGINT);` with `(void)raise(SIGINT);` in file test/testlock.c.
The `kill()` function is not available on Unix systems when compiling without system extensions enabled.
Closing a device file takes 0.01 to 0.5s, which can add up to
significant startup delays. The udev classification does not
require opening the actual device files, so, use it if possible,
and only fall back to opening the device and probing otherwise.

The idea is that if you have a `typedef Uint32 MyFlags` that has a bunch of
defines that are meant to be bitflags, you can pack them into the same wiki
page automatically.
This only works with `typedef`s that are _not_ struct/union/enums, and it
only pulls in `#define` lines that immediately follow the typedef line.
Even a blank line or a comment will signal to stop including lines for
this page!
Some backends, such as Wayland, don't support explicit mouse capture, and thus don't implement the backend function to do so, but do set/unset the capture flag on button events to handle cases where a button is pressed and the pointer is dragged outside the window.
If the backend doesn't support explicitly setting the mouse capture mode, manually clear the capture flag when the window has had the focus forcibly removed, to avoid sending bogus motion events as well as an assert condition.
Trying to capture the pointer via XGrabPointer() when XInput2 is in use will always fail with 'AlreadyGrabbed', since the pointer is already grabbed by XInput2.
- A refactor changed how SetupWindowData handled external windows where previously it was tracked
in a field of SDL_CocoaWindowData but now it is tracked by setting SDL_WINDOW_EXTERNAL in the
window flags. Removed the now unused field and updated the external window check in DestroyWindow.
The "jump magic" codepath was never written, and would have involved a lot
of low-level and platform/processor/compiler specific work.
A better solution is for compilers to treat the function call in the jump
table functions as a tail call, which would effectively produce the same
result in a portable way.
Clang already has a way to do this that we could add later. But this wouldn't
need a separate "jump magic" section.
This was hardcoded to disabled, since building it in bloated the binary
massively for little gain (one could probably accomplish this same thing
with ltrace or something).
If we need it, we'll pull it out of revision control.
