Basically fixing original Bug#427 reported by MArkus Elfring.
Unfortunately there are still more defines (in IrrCompileConfig.h) which also are not nice c++
Lots of files touched for very minor cleanup *sigh*

C++ has undefined behavior for identifiers starting with __ or with _ followed by an uppercase letter.
We still have many more (in IrrCompileConfig.h and in all header-guards), will likely replace those later as well.
As a workaround for users which might use irrlicht defines in their code, I've added the header irrLegacyDefines.h
Including that allows to continue using old defines for a while - or make it easier to have code which compiles
with old and new Irrlicht library versions.

Problem is that the mouse jumps when users have set a coordinate transformation matrix for their mouse on X11.
XWarpPointer first sets the correct coordinates, but X11 then moves the mouse wrongly to the scaled position on the next mouse event.
On X-Org bugtracker it's this bug: https://gitlab.freedesktop.org/xorg/xserver/-/issues/600
The fix needs compiling with _IRR_LINUX_X11_XINPUT2_ enabled (so far disabled by default)
Note: We only use XINPUT2 so far for touch-input... I hope this patch won't conflict with that.
Also I mix now IInput2 and X11 functions as getting the mouse-position still uses X11. But seems to work in my tests.

Thanks @TheBrokenRail for a patch proposal based on example code from esjeon (patch #322).
See https://sourceforge.net/p/irrlicht/patches/322
Original example code here: https://github.com/esjeon/xinput2-touch
Users have to enable _IRR_LINUX_X11_XINPUT2_ in IrrCompileConfig and link with Xi to make this work.
I rewrote the patch a bit and have no system for testing here, so this still needs some testing.
I also backported EET_TOUCH_INPUT_EVENT for this from the ogl-es branch.
