Title: VertexStream lockData() and unlockData() methods for bulk updates

I miss some means in VertexStream to perform bulk updates on its data without triggering signals, updating buinding values etc. each time I use VertexStream.set() method. Basically, I just want to get the whole data array, work with it in a "raw" fashion and then commit changes.
I propose 2 new methods:
lockData() to obtain exclusive write access to the stream data
unlockData() to commit changes and trigger buffer upload
