Move cryptographic algorithms and utilities to a new crypto mod
...
As we'd generally like the `lightning` crate to, over time, have
more modules rather than being very monolithic, we should move the
cryptographic things into their own module, which we do here.
We also take this opportunity to move stream adapters into their
own module and make clear that the ChaChaPoly `decrypt` method is
variable time.

Expose onion_message items directly rather than via re-exports
...
When we originally added the `onion_message` module, there weren't
a lot of public items in it, and it didn't make a lot of sense to
export the whole sub-module structure publicly. So, instead, we
exported the public items via re-exports directly in the
`onion_message` top-level module. However, as time went on, more
and more things entered the module, which left the top-level module
rather cluttered.
Worse, in 0.0.119, we exposed
`onion_message::messenger::SendSuccess` via the return type of
`send_message`, but forgot to re-export the enum itself, making
it impossible to actually use from external code.
Here we address both issues and simply replace the re-export with
the underlying sub-module structure.
