Refactor common code in the BoundingVolumeBuildVisitor.hxx.

It turns out that the database pager causes the texture image to be
unloaded after it is applied, so the image and its file name may not
be available for doing the livery substitution. Ask a work around we
set the name of the texture to its file name.
Also, add a NodeAndDrawableVisitor that descends into osg::Drawable.
That motivation for this is that it's a bad idea to modify state sets
that the osgDB::SharedStateManager might be keeping.
Create the local path in the right order in OptionsPusher. When
OptionsPusher is used, put it inside a new code block so the order of
destruction with respect to the mutex on reader functions id clear.
Add #include <algorithm> to top of ModelRegistry.cxx.
Change include syntax in PathOptions.cxx
The OSG reader plugins overwrite the path list passed in options with the local
directory of the file being read, forcing you to set the path list in
the Registry. I think this a bug, but in the meantime here's a workaround.
To set a path when loading model files, use an osg ReaderWriter::Options object.
Put locks in ModelRegistry::readNode and ModelRegistry::readImage to avoid
conflicts when files are loaded from both the pager and the main thread.
In a big effort to improve use of the object cache, provide a
ModelRegistryCallback template class with different policies for
substitution, caching, optimization, etc.
Change SGTexDataVarianceVistor to make StateSets static too.
Move SGReadFileCallback and all its help classes into a new
ModelRegistry class that also provides an interface to add custom
callbacks for specific file extensions. SGReaderWriterBTG uses that to
keep any further processing from being done on .btg files. Various
namespace-releated cleanup was done on this code too.
