SNI: added restriction on requesting host other than negotiated.

According to RFC 6066, client is not supposed to request a different server
name at the application layer.  Server implementations that rely upon these
names being equal must validate that a client did not send a different name
in HTTP request.  Current versions of Apache HTTP server always return 400
"Bad Request" in such cases.

There exist implementations however (e.g., SPDY) that rely on being able to
request different host names in one connection.  Given this, we only reject
requests with differing host names if verification of client certificates
is enabled in a corresponding server configuration.

An example of configuration that might not work as expected:

  server {
      listen 433 ssl default;
      return 404;
  }

  server {
      listen 433 ssl;

a certificate for example.org, and vice versa.

SNI: reset to default server if requested host was not found.
