/* Overview:
*
* We have an echo server, two proxy servers, two GProxy
* implementations, and two GProxyResolver implementations.
*
* The echo server runs at @server.server_addr (on
* @server.server_port).
*
* The two proxy servers, A and B, run on @proxy_a.port and
* @proxy_b.port, with @proxy_a.uri and @proxy_b.uri pointing to them.
* The "negotiation" with the two proxies is just sending the single
* letter "a" or "b" and receiving it back in uppercase; the proxy
* then connects to @server_addr.
*
* Proxy A supports "alpha://" URIs, and does not support hostname
* resolution, and Proxy B supports "beta://" URIs, and does support
* hostname resolution (but it just ignores the hostname and always
* connects to @server_addr anyway).
*
* The default GProxyResolver (GTestProxyResolver) looks at its URI
* and returns [ "direct://" ] for "simple://" URIs, and [
* proxy_a.uri, proxy_b.uri ] for other URIs. The other GProxyResolver
* (GTestAltProxyResolver) always returns [ proxy_a.uri ].
