My primary motivation at this point is to use it for basic proxy auth.
(specify "Proxy-Authorization" header)
But there can be other use cases for proxy-specific extra headers.
If/when we want to support other non-trivial auth methods, probably
a callback-based mechanism will be necessary. But at this point,
this serves my purpose well.
Use a separate webclient_context for tunnel establishment.
I chose this way (instead of having tunnelling steps in
the state machine of a single webclient_context) because
I want to allow tunnelling of non-HTTP protocols sooner or later.
Add a primitive API for tunnel establishment.
(WEBCLIENT_FLAG_TUNNEL and webclient_get_tunnel)
I plan to use this to implement https proxy support.
That is, the primary user will be webclient itself.

When making the following change, I haven't noticed that
g_httpuseragentfields contains a "Connection" header.
```

webclient: Always use "connection: close" for HTTP 1.1 for now
* This matches the HTTP 1.0 behavior.
* Persistent connection doesn't make much sense with the current API.
```
It seems that some servers are not happy with the duplicated header
and ignore them. (and do the default keep-alive for HTTP 1.1)
eg. Azure Blob (global)
