This changes the LOG macro to be varadic removing the need for all
callsites to have double bracketing and allows for future improvement
on how we use the logging macros.
The callsites were changed with coccinelle and the changes checked by
hand. Compile tested for several frontends but not all.
A formatting annotation has also been added which allows the compiler
to check the parameters and types passed to the logging.
- Currently only libnsfb's SDL surface supports resizing.
- Flickers like crazy while resizing. Possibly because the SDL
surface is not set to use double buffering.
- The internal widget library, fbtk, was never intended for this,
as such it has no knowledge of how a widget should be positioned
with respect to its parent.
This means the top level window has to track everything and move
them itself.
