core: Move write_serial() prototype to core.h

There's nothing inherently BIOS-specific about write_serial(), so it
doesn't make sense to have it in bios.h. Move the prototype to core.h
so that files can access the prototype without pulling in all the BIOS
symbols. Also add some missing function prototypes while we're at it.
