* Seal off some buffer functions so that only the higher-level IO functions
are exposed.
* Using the above change to buffer, add support to tunala for displaying
traffic totals when a tunnel closes. Useful in debugging and analysis -
you get to see the total encrypted traffic versus the total tunneled
traffic. This shows not only how much expansion your data suffers from
SSL (a lot if you send/receive a few bytes at a time), but also the
overhead of SSL handshaking relative to the payload sent through the
tunnel. This is controlled by the "-out_totals" switch to tunala.
* Fix and tweak some bits in the README.
Eg. sample output of "-out_totals" from a tunnel client when tunneling a brief
"telnet" session.
Tunnel closing, traffic stats follow
SSL (network) traffic to/from server; 7305 bytes in, 3475 bytes out
tunnelled data to/from server; 4295 bytes in, 186 bytes out
