- Reject a negative FILECONTENTS_SIZE result: m_lSize is unsigned, so a
negative value became a huge bogus stream size that keeps reads going.
- Use a unique per-stream counter as the CLIPRDR streamId instead of a
truncated IStream pointer, which could collide or be reused after free
(and leaked heap addresses to the peer).
- Add req_f_request_mutex to serialize whole file-contents request/response
cycles, enforcing the previously assumed one-outstanding-request
invariant when multiple streams are read concurrently. Bounded acquire
so a wedged request fails the read instead of hanging a consumer.

Cover the zeroed optional request fields, stream ID filtering,
oversized/NULL response rejection and the zero-byte EOF path.
