Introduce several improvements to improve the stability of dual-channel
replication and fix compatibility issues.
1. Make dual-channel-replication tests more reliable: use pause instead
of forced sleep.
2. Fix race conditions when freeing RDB client.
3. Check if sync was stopped during local buffer streaming.
4. Fix $ENDOFFSET reply format to work on 32-bit machines too.
