runtime: Custom Buffer/Accelerator Device Support - Milestone 1
Custom Buffer/Accelerator Device Support - Milestone 1 changes:
* Refactored existing single mapped buffer code and created single
mapped buffer abstraction; wrapping within single mapped buffers
is handled explicitly by input blocked and output blocked
callbacks that are called from block_executor
* Added simple custom buffer allocation interface (NOTE: this
interface will change for milestone 2)
* Accelerated blocks are still responsible for data transfer but the
custom buffer interface eliminates the double copy problem
