32d8d23cd0 Re-apply 5acd47169884, Add a shared-memory based orc::MemoryMapper, with fixes. 
The original commit was reverted in 3e9cc543f223 due to buildbot failures, which
should be fixed by the addition of dependencies on librt.

5acd471698 [ORC] Add a shared-memory based orc::MemoryMapper. 
This is an implementation of orc::MemoryMapper that maps shared memory
pages in both executor and controller process and writes directly to
them avoiding transferring content over EPC. All allocations are properly
deinitialized automatically on the executor side at shutdown by the
ExecutorSharedMemoryMapperService.
