fifo: Add support for multi-process

For multi-process, the indices are allocated in separate shared memory.
This permits the buffer, write index, and throttling read index to each
have their own protection.

By default, the indices are allocated within the object to retain
API compatibility for the single-process case.

Test: in next CL
