X11 scancode mapping cleanup
* Consolidated scancode mapping tables into a single location for all backends
* Verified that the xfree86_scancode_table2 is largely identical to the Linux scancode table
* Updated the Linux scancode table with the latest kernel keycodes (still unmapped)
* Route X11 keysym -> scancode mapping through the linux scancode table (which a few hand-written exceptions), which will allow mappings to automatically get picked up as they are added in the Linux scancode table
* Disabled verbose reporting of missing keysym mappings, we have enough data for now

events: Don't lose window RESIZED events during SIZED_CHANGED processing.
Previously, calling SDL_SendWindowEvent for a SIZED_CHANGED event would
filter the queue to remove RESIZED and SIZED_CHANGED events, so you don't
overflow the queue with obsolete data, but any RESIZED events would be
lost in this process.
Now we note if there was a RESIZED pending and replace it with a new
event using the same dimensions as the new SIZED_CHANGED event. This fixes
cases where an app is only listening for RESIZED events and thus might
lose important information in some cases.
Fixes #5925.

Improve behavior of SDL_events_need_periodic_poll() and SDL_events_need_polling()
SDL_events_need_periodic_poll() and SDL_events_need_polling() are intended to allow the event loop to update joysticks and/or sensors if needed, however those systems only update when the SDL_update_joysticks and/or SDL_update_sensors variables are true. This change brings the behavior of these functions in line with if work will actually need to be performed.
This change allows the hints for AUTO_UPDATE to influence the polling behavior of the event loop such that an app can choose to update joysticks/sensors itself and avoid the expense of constantly sleeping and waking the event loop. Additionally in makes these functions marginally faster in some situations by not searching the active events.

Fix updating SDL_update_joysticks and SDL_update_sensors in response to hint changes
Hint callbacks are called before the actual value in the hint is changed, so the functions SDL_AutoUpdateJoysticksChanged and SDL_AutoUpdateSensorsChanged were not actually properly updating their respective variables in repsonse to their auto update hint changing.
Instead, we pull the new hint value out of the value passed into the callback and use that to update the variables. Assume true on a null value as that was the previous behavior and it matches with the default values of SDL_update_joysticks/SDL_update_sensors.

Fix relative mouse input for Unvanquished (unvanquished.net)
Here's an IRC dump that hopefully explains the issue this fixes:
> I'm debugging something odd where, for a libre game,
unvanquished.net (a FPS), relative mouse input in fullscreen is
buggy
> it's like, working mostly ok, but it has a weird
performance/cleanup bug
> after some time in relative mouse input mode, some time as low
as 15s, usually more, the SDL sends A LOT of relative mouse
input per frame
> almost all of which have xrel==0 && yrel==0
> by A LOT, I mean that after ~1min, it's usually in the
thousands per frame
> each frame, a while ( SDL_PollEvent( &e)) loop reads the
inputs, but it seems SDL is not clearing the list.
> one way to clear the list is to open the in-game console or
menu, which switches the input mode to absolute, then close it
which gets a working relative input mode (for some time at least)
> I've shown the issue to be present with SDL2.0.20 but not with
2.0.14 on my system
> some other players on Arch Linux (SDL2.0.20) report a possibly
related issue, where some keys seem to be pressed at random
> I've did some bisection on SDL master, and I've found that
there are actually two commits involved, one breaking it
totally (no input at all), and one fixing it partially (with
the problem described above)
First related commit that breaks it totally:
commit 82793ac279d19b5bde8fc2bd62877b05ba5a76e0
Author: Sam Lantinga <slouken@libsdl.org>
Date: Thu Oct 14 14:26:21 2021 -0700
Fixed mouse warping while in relative mode

Second related commit, that halfway fixes it:
commit 31f8c3ef4409a93fafa894b78c2ce176bd0c3cf3
Author: Sam Lantinga <slouken@libsdl.org>
Date: Thu Jan 6 11:27:44 2022 -0800
Fixed event pump starvation if the application frequently pushes its own events
Reverting the first commit did fix the issue for me, but would

bug, and contains some early investigation.

events: Only add sentinels for pumping done inside SDL_WaitEventTimeout()
We don't want to catch explicit SDL_PumpEvents() calls by the application with
our polling check to avoid stale data. If the call to SDL_PumpEvents() produced
no events, there will be a sentinel sitting in the queue that will cause
SDL_PollEvent() to immediately return 0 next time it is called.
Our SDL_WaitEventTimeout() implementation avoids this issue by always popping
an event after calling SDL_PumpEvents(). This will remove the new sentinel if
we didn't get any new events.

Fixed mouse warping while in relative mode
We should get a mouse event with an absolute position and no relative motion and shouldn't change the OS cursor position at all

Fix weak enforcement of timeouts in SDL_WaitEventTimeout_Device. This will loop pumping events and waiting for a system event to come in. However not all system events will turn into an SDL event. It's not unusual for a Windows message to be some internal thing that SDL doesn't convert into a message. In that case the loop will simple circle but not exit. As long as such messages are coming in the loop will continue to run regardless of the timeout. When messages finally stop it'll still wait for the full timeout so you can have arbitrarily long delays.
Instead do an absolute elapsed time check since the start of the wait. If that is exceeded during any iteration the routine exits as the timeout has elapsed.

Use the new SDL_clamp() macro where sensible
There were a few places throughout the SDL code where values were
clamped using SDL_min() and SDL_max(). Now that we have an SDL_clamp()
macro, use this instead.

Get the window size for the window receiving the mouse motion
This is the mouse focus except in the case where relative motion is enabled and the mouse is over a window floating on top of the application window (e.g. the taskbar)

Relative mouse mode grab is based on the window with the input focus
This fixes restoring the cursor clip rectangle after the mouse has moved off of the window.
Also try to better synchronize cursor visibility with mouse position changes when changing relative mode. This doesn't work perfectly, but it seems to improve things on Windows.

Avoid warping the cursor to the center of the window when not in relative_warp_mode
When relative mode is enabled and not using warp mode, the cursor is
being clipped to the window. Therefore there is no reason to restore the
cursor position to the center.
Avoiding the warp to center simplifies mouse position event flow, as we
are no longer potentially receiving mouse events for the automated
movement of the cursor and can be (mostly) assured that an incoming
event from the windowing system is that of external means.

Pump events each time through the loop in SDL_WaitEventTimeout_Device()
Not only is it more efficient to batch process pending events, it is
necessary for correctness with the Win32 backend. WIN_PumpEvents() runs
periodic updates of the cursor clip region and disambiguation of
left and right shift keys in addition to standard event processing.

Only queue one wakeup event per wait

SDL_keyboard.c: Add bounds guards when assigning to the scancode array.
Based on a patch by Jochen Schäfer <josch1710@live.de> :
On a T420 pressing the ACPI button for volume control, big scancodes
were emitted. This was causing an overflow, because missing guards.

Don't skip sending wakeups for the current thread
We can be in a situation where we receive a win32 hook callback on the same
thread that is currently waiting. In that case, we do still need to trigger
a wakeup when an event is pushed because the hook itself won't necessarily
do that (depending on what we return from the hook).

Call SDL_SendWakeupEvent() directly from SDL_PeepEvent()
SDL_PeepEvent() is a documented public API, so we must properly support
waking a waiting thread in SDL_WaitEventTimeout() with SDL_PeepEvent().

Modifies WaitEvent and WaitEventTimeout to actually wait instead of polling
When possible use native os functions to make a blocking call waiting for
an incoming event. Previous behavior was to continuously poll the event
queue with a small delay between each poll.
The blocking call uses a new optional video driver event,
WaitEventTimeout, if available. It is called only if an window
already shown is available. If present the window is designated
using the variable wakeup_window to receive a wakeup event if
needed.
The WaitEventTimeout function accept a timeout parameter. If
positive the call will wait for an event or return if the timeout
expired without any event. If the timeout is zero it will
implement a polling behavior. If the timeout is negative the
function will block indefinetely waiting for an event.
To let the main thread sees events sent form a different thread
a "wake-up" signal is sent to the main thread if the main thread
is in a blocking state. The wake-up event is sent to the designated
wakeup_window if present.
The wake-up event is sent only if the PushEvent call is coming
from a different thread. Before sending the wake-up event
the ID of the thread making the blocking call is saved using the
variable blocking_thread_id and it is compared to the current
thread's id to decide if the wake-up event should be sent.
Two new optional video device methods are introduced:
WaitEventTimeout
SendWakeupEvent
in addition the mutex
wakeup_lock
which is defined and initialized but only for the drivers supporting the
methods above.
If the methods are not present the system behaves as previously
performing a periodic polling of the events queue.
The blocking call is disabled if a joystick or sensor is detected
and falls back to previous behavior.
