Make sure that each C file in `girepository/` includes its corresponding

function contains the symbol visibility macros. This fixes symbol export
(`dllexport`) on Windows platforms.

The pkg-config file sets the include directory to the level above
`girepository/`, just like with GIO, GObject and GModule.

Add the SPDX license runes to all the files which have an obvious
copyright header already. This is a mechanical edit.
