Use TLS SNI extension in the client, if pyOpenSSL is available.

This fixes resource fetches to https servers that require the
extension. These are typically cdn servers.

Example of such server, without SNI:

$ openssl s_client -connect cdn3.vox-cdn.com:443
CONNECTED(00000003)
140434795792032:error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure:s23_clnt.c:732:
...

With SNI:

$ openssl s_client -connect cdn3.vox-cdn.com:443 -servername cdn3.vox-cdn.com
CONNECTED(00000003)
depth=3 C = US, O = "The Go Daddy Group, Inc.", OU = Go Daddy Class 2
Certification Authority

Can you record HTTPS pages? I'm still getting SSL proxy error

Yeah. I had problems with some https sites (the ones requiring SNI), not all of them. So if you have problems with all HTTPS pages, you have a different problem :)

I'm using chromium with --ignore-certificate-errors. Also mainly using it with --testing-fixed-http-port=$1 --testing-fixed-https-port=$2 , though I tried to test also with the dns spoofing .

I don't have http or https proxies for the web-page-replay, though. I don't know if they work, and unfortunately I could not test if this patch breaks them or not..
