about https support for transparent proxy

Hi, all

Many people want https support for transparent proxy using tproxy.
Now, squid is not supported. Certainly, https support may make
security problem, but I think it's useful as an "optional extra".

As a trial, I implemented the patch for https support,
(but it's still too ad-hoc...)

What do you think about https support ?

- Environment
  squid-3.1.0.7

Sincerely,
