Fixes battery level dropping to empty with the Qanba Drone Arcade Stick.
It looks like we might also be able to skip the check for all third party controllers, but I think this is the right thing to do for Sony controllers as well.
In all cases they were using SDL_SCANCODE_TABLE_XFREE86_2 with some keycodes remapped or fewer than expected keycodes. This adds a sanity check that catches all of them and gives them the right scancode table.
If we can't find the X11 keysym, it's likely that either the keysym is NoSymbol, in which case we won't hit it anyway, or it's been mapped to a character, in which case the existing mapping is correct for the scancode and the character will be reflected in the keycode mapping.
* 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
The original code mapped incorrectly from [min, max] to [-32768, 32512], the upper bound being SDL_JOYSTICK_AXIS_MAX - 255 instead of SDL_JOYSTICK_AXIS_MAX.
If this assertion fails on some platform (unlikely), we will need a
third implementation for SwapLongLE().

The check for whether to use a 32- or 64-bit swap for an array of long
values always took the 64-bit path, because <limits.h> wasn't included
and therefore ULONG_MAX wasn't defined. Turn this into a runtime check,
which a reasonable compiler will optimize into a constant.
This fixes testevdev failures on 32-bit big-endian platforms such as hppa
and older powerpc. Little-endian and/or 64-bit platforms are unaffected.

This will only log things going through dynapi, which means it won't
do anything if dynapi is disabled for a given build, but also things
that call the `*_REAL` version of an API won't log either (which is
to say, if an internal piece of SDL calls a public API, it won't log
it, but if an application calls that same entry point, it will).
Since this just inserts a different function pointer, unless you
explicitly request this at runtime, it won't add any overhead, and,
of course, the entire thing can be turned off with a single #define
so it doesn't even add extra unused code to the shared library if
the kill switch is flipped.
