After we generate the event, we expect users to spawn a timer in
the background and let us know when it finishes. However, if the
user shuts down before the timer fires, the user will restart and
have no idea that HTLCs are waiting to be forwarded/received.

To fix this, instead of serializing PendingHTLCsForwardable events
to disk while they're pending (before the user starts the timer),

Make `NetworkGraph` Clone-able again

There isn't a lot of user-utility for cloning `NetworkGraph`
directly (its a rather large struct, and there probably isn't a lot
of reason to have *multiple* `NetworkGraph`s). Thus, when locks
were pushed down into it, the `Clone`-ability of it was dropped as
well.

Sadly, mapping the Java memory model onto:
 * `Read`-ing a `NetworkGraph`, creating a Java-owned
   `NetworkGraph` object that the JVM will destruct for us,
 * Passing it to a `NetGraphMsgHandler`, which now expects to own
   the `NetworkGraph`, including destructing it,
isn't really practical without adding a clone in between.

Given this, and the fact that there's nothing inherently wrong with
clone-ing a `NetworkGraph`, we simply re-add `Clone` here.

Make method time on trait impl explitit to help bindings generator

Associated types in C bindings is somewhat of a misnomer - we
concretize each trait to a single struct. Thus, different trait
implementations must still have the same type, which defeats the
point of associated types.

In this particular case, however, we can reasonably special-case
the `Infallible` type, as an instance of it existing implies
something has gone horribly wrong.

In order to help our bindings code figure out how to do so when
referencing a parent trait's associated type, we specify the
explicit type in the implementation method signature.

Use Infallible for the unconstructable default custom message type

When we landed custom messages, we used the empty tuple for the
custom message type for `IgnoringMessageHandler`. This was fine,
except that we also implemented `Writeable` to panic when writing
a `()`. Later, we added support for anchor output construction in
CommitmentTransaction, signified by setting a field to `Some(())`,
which is serialized as-is.

This causes us to panic when writing a `CommitmentTransaction`
with `opt_anchors` set. Note that we never set it inside of LDK,
but downstream users may.

Instead, we implement `Writeable` to write nothing for `()` and use
`core::convert::Infallible` for the default custom message type as
it is, appropriately, unconstructable.

This also makes it easier to implement various things in bindings,

unreachable.

`wire::Type` is only (publicly) used as the `CustomMessage`

trait bounds on `Debug` and `Writeable`. The documentation for

this is the one place it is used.

To make this more clear, we move the type bounds onto the trait
