Add support for HTTP proxies.
* module/web/http.scm (http-proxy-port?, set-http-proxy-port?!): New
exported procedures.
(write-request-line): If we're using an http proxy, write an
absolute-URI in the request line.
* module/web/client.scm: Import (web http).
(current-http-proxy): New exported parameter.
(open-socket-for-uri): If 'current-http-proxy' is not false,
connect to the proxy instead of the URI host, and use
'set-http-proxy-port?!' to make note of that fact.
* doc/ref/web.texi (Web Client): Document 'current-http-proxy'.
