The call_site stuff uses cu_offset, also defined in gdbtypes.h, so cu_offset also needs to move somewhere else (otherwise, call-site.h will need to include gdbtypes.h, and we are back to square 1). I could move cu_offset to the future new file dwarf2/call-site.h, but it doesn't sound like a good place for it, at cu_offset is not specific to call sites, it's used throughout dwarf2/. So, move it to its own file, dwarf2/types.h. For now, gdbtypes.h includes dwarf2/types.h, but that will be removed once the call site stuff is moved to its own file. Move sect_offset with it too. sect_offset is not a DWARF-specific concept, but for the moment it is only used in dwarf2/.
