inets httpc: TLS via proxy

Introduces new option htts_proxy so that it is possible
to have different proxies for http and https. The new option
defaults to the old proxy option.

Implements HTTP-1.1 extension method CONNECT to establish SSL/TLS tunnel

We choose not to implement "TLS upgrade" as defined by RFC 2817 as
this method of upgrade is vulnerable to man in the middle attacks,
can be easily broken by proxies and does not seem to be widely adopted.
