Applied part of the patch submitted by Carl Hasselskog on dev list. Fixed a NullPointerException that occurred for instance when an SSLSocket called getTcpNoDelay() on PseudoTCPSocket. PseudoTcpSocketImpl returned null but the SSLSocket assumed it would be true/false. Improved logging to better detect if someone is trying to get some other option that would return null.

Decreased receive buffer size in PseudoTcpSocketImpl that caused invalid packets to be logged into .pcap file. Filled missing javadoc.
