Message:

Moved Registry::ReadFileCallback? + WriteFileCallback?, and osgDB::ReaderWriter::Options into their own separate Options file and into the osgDB namespace.

Introduced a new callback osgDB::FindFileCallback? that overrides the default behavior of findDataFile/findLibraryFile.

Introduced support for assigning ReaderWriter::Options directory to PagedLOD.

Introduced new osgDB::FileLocationCallback? for assistancing the DatabasePager? to know when a file is hosted on a local or remote file system.
