Protocol's get() method no longer takes ownership of the URI. HTTP is the

exception rather than the rule; we may as well keep things clean for other

Gave asynchronous operations approximate POSIX signal semantics. This
...
will enable us to cascade async operations, which is necessary in order to
properly support DNS. (For example, an HTTP request may have to redirect
to a new location and will have to perform a new DNS lookup, so we can't
just rely on doing the name lookup at the time of parsing the initial
URL).
Anything other than HTTP is probably broken right now; I'll fix the others
up asap.

Make TCP give up immediately when it receives -ENETUNREACH from

tcpip_tx(). This avoids the irritating wait when you accidentally type
