Add HTTP proxy support to http-client

[sjamaan]

Figure out how to set up a local proxy to test this, and implement it.

Code can be cribbed from the Chicken 3 "http" egg's http-client

I would disagree. The code I wrote for chicken3/http-client is a workaround.
It was OK for chicken3/http-client, because the entire code was rather hack.

Chicken4/http-client, as far as I understand, is cleaner and strict for the protocol, so careful reading of RFC docs might be needed.

[sjamaan]

Please test http-client trunk. I've added basic proxy support in [20749]

How to use it is documented in the wiki page for http-client in a section called "Proxy support". By default, it should "just work" (ie, it picks up commonly-used environment variables for proxies).

I hope to add authentication support for proxies soon.

[sjamaan]

Proxy authentication was added in [20759].

You'll need to update to [20760], the proxy implementation caused something else to break (null paths when not using a proxy).

[sjamaan]

Make that [20761], the other one is a documentation commit :)

Verified to work in a message to chicken-users
