Implement ipc-channel on Windows

This implementation uses named pipes on Windows, with auto-generated uuid
names.  It takes advantage of DuplicateHandle to clone handles to target
processes when sending handles cross-process.  Shared memory is implemented
using anonymous file mappings.  select() and friends are implemented using
IO Completion Ports.
