Robert Bragg 7901e30aac buffer: adds immutable ref/unref mechanism
This adds an internal mechanism to mark that a buffer is in-use so that
a warning can be generated if the user attempts to modify the buffer.

The plans is for the journal to use this mechanism so that we can warn
users about mid-scene modifications of buffers.
