Subject: [PATCH] Wrap public declarations with G_BEGIN_DECLS/G_END_DECLS

Glib release 2.67.3 started conditionally using some C++ code[1] in the
public headers and it's no longer legal to include "glib.h" or anything
that includes it transitively from `extern "C"` block.

The solution recommended by the glib developers is to enclose all
declarations in a header within G_BEGIN_DECLS and G_END_DECLS as shown
in gobject developer manual[2].
