1. Moved sslKeyFails. 2. Added sslEphemeralMisses, sslEncryptedConns, sslDecodeFails. 3. Removed the Rehandshake stats as the sniffer does not support rehandshaking. 4. Removed two of the per second stats as they seemed redundant. 5. Added a function to atomically read and reset the sniffer statistics.
