Now RetryError is parameterized on an underlying error type.

As with the tor-chanmgr code, the circuit manager is now implemented
using an AbstractCircMgr type that uses traits to abstract the
particular behavior of other types that it uses. (Specifically:
circuits, building circuits, and telling whether one circuit usage
is compatible with another.) Abstracting out the dependencies in
this ways makes it possible to test the circuit manager without
having to actually build real circuits.
This commit also introduces new behavior for handling pending
circuit requests. Upon getting a new request, first we check to see
if there's an existing circuit we can use. If there isn't, we look
for pending circuits and wait for them. If there aren't any pending
circuits we can use, we launch one or more, and wait for them.
So far, that's the same as the old behavior. But here's a change:
if, while we are waiting for some pending circuits, a different
circuit is completed, and it's one we could use, then the task that
was building _that_ circuit will tell us: "please look at this
circuit". This gives us better changes of getting a usable circuit
fast.
Minor changes:
* The Error type in CircMgr no longer uses anyhow; several errors
have been simplified.
* We've gotten more formal about the relationship between circuit
usage and target usage.

Public function so an application can use to build a circuit using a
custom path.

dalek-crypto is stuck on rand_core 0.5.1, so we've been stuck too.
This commit introduces a compatibility module so that we can wrap
new rand_core instances to make them backward compatible.

This is fairly ugly and I think I'll need to mess around with the
feature configuration a while until we get something that's pleasant
to develop with. This still seems like a good idea, though, since
we _will_ need to be executor-agnostic in the end, or we'll have no
way to handle wasm or embedded environments.
Later down the road, we'll probably want to use futures::Executor or
futures::Spawn more than having global entry points in
tor_rtcompat. That would probably make our feature story simpler.
Tokio is the default now, since tokio seems to be more heavily used
for performance-critical stuff.
This patch breaks tests; the next one will fix them, albeit
questionably.

Like tor_llcrypto, this crate is meant to expose only the part of
other crates (in this case, a async runtime crate) that we use.
