runtime: Custom Buffer/Accelerator Device Support - Milestone 2
Completion of custom buffer/accelerator device support changes:
* Improved custom buffer interface by removing awkward memory
allocation functions from the block class
* Increased flexibility for creating custom buffers by allowing
creation of buffer_single_mapped subclasses
* Fully incorporated data movement abstraction into the custom
buffer interface and the runtime itself; accelerated blocks are no
longer directly responsible for their own data movement
* Zero copy back-to-back accelerated blocks are now supported (data
no longer needs to be moved back to the host between each block)
