Fix some warnings and header-file improvement

Ther were lot of 'extern' declarations in the x-files, so called
'imports from xboard.c', (sometimes backend.c) which logically belonged
in xboard.h (backend.h) to ensure their uniform definition. These have
now been moved there. Some prototypes have been added in xboard.h as
well, for functions that needed calling from xoptions.c.
