084ef28708 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.

0052b2c5c3 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

80aa4f20a9 Make channel open confs configurable (and change from 12 to 6) 
This fixes compatibility with c-lightning etc as they won't accept
a minimum_depth of 12.

74588b2519 Send back the actual received amount, not expected on HTLC fails 
This resolves an incorrect implementation of the spec and fixes a
major privacy leak.

Fixes GH #289.

49d63302c3 Add a fuzz target to test monitor update failure handling

Travis' runtime limits.

90ce97198c Simplify and expand logging in is_resolving_htlc_output 
This clarifies all the conditions we can hit and also ensures they
are all logged in a clear and consistent manner.

cdf9b4f8ba Add option to use libfuzzer sys in full_stack_target 
Note that there doesn't appear to be a way to conditionally set
 #[no_main] so that has to happen manually at compile-time.

8e07259326 Use bitcoin_hashes' Ripemd160/Hash160 from rust-crypto+rust-bitcoin 
Note that this requires rewriting full_stack_target tests, which
sucks, but it does let the fuzzer hit more stuff since the real
ripemd160 isn't ever actually called anymore.

caeff85368 Update incorrect_payment_amount generation/handling for BOLT uptd 
ie dont generate them as they're a really obvious privacy leak.
Luckily we were already handling them the same aside from log
printing so don't have to touch anything there. I was lazy in
updating tests but it only effects log printing, so whatever.

221bfa6bd4 Move monitor-generated HTLC event handling to manager event-getters 
This is somewhat awkward, but prevents a slew of duplicate events.
Really this should probably be more explicit, but would be easy to
move that along with a slew of block_connected-event-processing
refactors, see-also GH #80.

This affects full_stack_target only on accident cause the demo test
didn't continue onwards with another block connection.
