Avoid warnings on Windows

Remove unused functions, or put in #if 0 if potentially useful. Make
internal functions used just in one file static. Use -Werror after all
also on Windows. Construct the installation root from the location of
the dbus DLL, not from the location of the program .exe of the
process.
