The original CL had a bug in the unit tests where an incorrect
parameter was passed to mach_vm_region.

SharedMemory.
base::FileDescriptor has a property |auto_close| that is used to indicate that
when the object is passed to an IPC message, the message takes ownership of the
underlying OS handle. Since SharedMemoryHandle needs to be interchangeable with
base::FileDescriptor, I added a property with similar functionality named
|ownership_passes_to_ipc_|.
The method ShareToProcess() is used to lower the current and maximum protection
of the underlying OS handle before it is transferred to a different process. I
implemented this functionality for Mach memory objects.

They are about to be used by a second test suite. This CL is intended as a
refactor with no behavioral change.
