add warning control macro set
Add a way to toggle on and off a warning for a specific section of code.
This supports clang and gcc, and has no effect for any other compilers.
This follows commit bfc29ba442dbb65599f29fe5aa44c6219ed0d3a8 and
provides a generic way to handle warnings in such corner cases.
To disable a warning enabled by "-Wsome-warning" for a specific code:
WARN_OFF(some-warning) // disable compiler warning
; /* some code */
WARN_ON(some-warning) // enable the warning again
