Remove a few warnings when compiling Qt and unexport some functions.

Make some functions static that are not used anywhere but in the
current file. Others that are used, add the declaration to the _p.h to
ensure we don't forget about them.

Finally, there's no need to enable debugging code if it's not used
anywhere.
