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.

This changes the behaviour on Win32 somewhat when Windows returned a CURSOR_SUPPRESSED state (touch-screen input hiding cursor globally).
Previously we set IsVisible it to false when CURSOR_SUPPRESSED was set.
Also we handle the CURSOR_SUPPRESSED state slightly different now and still try to hide cursors once when requested.
Reason for the change is that the old behaviour made it harder to recover from touch-screens hiding the cursor because Irrlicht didn't
know anymore which state is _should_ have. This also unifies the behaviour on all drivers as the other drivers already returned the visible
flag independent of the system being able to actually show the cursor.
