Randomize initial onion packet data.
...
This avoids at least the trivial hop count discovery attack, though
other obvious ones remain and are slightly harder to avoid.

Add dyn tags in fuzz_targets
...
We only support newish rust in fuzz_targets, so this is fine.

Drop msgs bound for a disconnecting peer at disconnect time
...
This simplifies chanmon_fail_consistency greatly and makes it a
tiny bit more realistic. It also sets us up for more
disconnect-relatex events without the complexity blowing up.

Make rand a dev-dep by having the user randomize HTLC forward delay
...
This removes the last calls to rand outside of test and moves the
dep to a dev-dependency, dropping our fuzz rng wrapper in the
process.

Stop using rng in peer_channel_encryptor to generate ephemeral keys
...
This removes the bulk of our reliance on the rand crate in non-test
envs, paving a way towards a syscall-less rust-lightning and WASM.
Since this is a breaking change for full_stack_target (and several
fuzz targets), go ahead and make other changes to make things more
distinct.

Provide peer local_features to handle_open_channel/accept_channel
...
Peer may send us a shutdown_scriptpubkey in open_channel or
accept_channel messages. Before to enforce this policy on channel
closing, we want to be sure that our peer has opt-in to it.
Extend LocalFeatures new method visibilty from crate to public
for fuzz tests

This fixes compatibility with c-lightning etc as they won't accept
a minimum_depth of 12.

Travis' runtime limits.
