ureq doesn't actually support the semantics of CONNECT, since it doesn't
offer a bidirectional channel on a Response. So I'm fairly confident no
one is using these methods.
This defines a new trait `Resolver`, which turns an address into a
Vec<SocketAddr>. It also provides an implementation of Resolver for
`Fn(&str)` so it's easy to define simple resolvers with a closure.

By using `RUSTFLAGS="-D dead_code -D unused-variables -D unused"`, we tell
the compiler to upgrade warnings for unused code to errors. This combined
with a more elaborate test matrix means we can have the CI catch feature
flag combos that cause warnings.
`Some(AgentState)` seem to be assumed pretty much everywhere. I could not
find any test or piece of code hinting at how `None` should be interpreted,
or even see how a state of `None` could even be constructed.

Adds set_max_idle_connections and set_max_idle_connections_per_host.
This turns the values of Pool.recycle into a VecDeque of Streams for the same PoolKey.
The freshest stream (most recently used) is at the back; the stalest stream is at the front.
This also removes the invariant "Each PoolKey exists in recycle at most once and lru at
most once," replacing it with "each PoolKey has the same number of entries in lru as in
recycle."
Fixes#110
PoolKey calls unwrap() on an option that can be None. Specifically, the
local variable `port` can be None when PoolKey is constructed with a Url
whose scheme is unrecognized in url.port_or_known_default().
To fix that, make port an Option. Also, make scheme part of the PoolKey.
This prevents, for instance, a stream opened for `https://example.com:9999`
being reused on a request for `http://example.com:9999`.
Remove the test-only pool.get() accessor. This was used in only one test,
agent_pool in range.rs. This seemed like it was testing the agent more
than it was testing ranges, so I moved it to agent.rs and edited to
remove the range-testing parts.
Also, reject unrecognized URLs earlier in connect_socket so they don't
reach try_get_connection.
Adds some feature guards, and removes an unnecessary feature guard
around a call to connect_https (there's an implementation available for
non-TLS that returns UnknownScheme).
Also, remove unnecessary agent.state() method that was only available in
TLS builds. The state field is directly accessible within the crate, and
can be used in both TLS and non-TLS builds.
