Add a RenderTarget class to manage and annotate FBOs

I want to have deferred lighting support at some point, and it requires
multiple outputs from the geometry rasterization stage.  There needs to
be some way to annotate which buffer holds which information.

Remove dynamic allocation from VertexFormat

On 64-bit systems the pointer takes eight bytes, and a typical malloc
implementation will have two pointers worth of overhead.  Vertex formats
hardly ever reach even eight components, so it's cheaper to just store
a fixed-size array in the class itself.

Ensure that program syntax nodes get deep-copied properly

The changes in 57c1139 prevented copies happening even when they should,
so the shared section got inserted into shader stages by reference.  This
caused some funny business with the variable resolver and unused variable
locator.

Containers of nodes must have RefPtrs inside them, since insertions will
create some temporary copies of the element and with NodePtr that would
trigger copying the node as well.  So the cloning of nodes is performed
when the container itself is copied.
