f78d7299d6 Also fwd channel_update and node_announcement immediately 
Not really sure why the API was different for channel_announcement,
but this brings everything in sync.

b9a793a0a0 Correct excess-data handling in NodeAnnouncement 
Breaks parsing of padding within addresses, but nothing currently
generates such messages, and I'm proposing we remove it in the spec

42e908883f Return a malformed HTLC message when ephemeral pubkey is garbage 
This resolves a spec-compliance bug with BOLT 4 where we simply
failed to deserialize the message and thus could never return an
HTLC failure message. However, note that BOLT 4 incorrectly hints
that a non-malformed message should be used ("...MUST report a
route failure to the origin node") which we cannot do as we cannot
derive a SharedSecret to encrypt a regular update_fail_htlc message

ab00e4ccff Merge HTLC-update events, remove FailHTLC ErrorAction 
UpdateFailHTLC isn't really an error anymore now that its handled
async after channel commitment (as required by BOLT 2), and since
its unused this is free. To resolve the TODO which intended to use
it for HTLC failure when trying to route forwards, we instead opt
to merge all the HTLC update events into one UpdateHTLCs event
which just contains a CommitmentUpdate object.

66023b7886 Update NodeAnnouncement addr deserialization to check addr len. 
This more aggressively checks the message contents are correct
before returning WrongLength so existing fuzz setup has an easier
time.

0c1f47807a [msgs::ChannelReestablish] implement encoding and decoding 
Summary:

Implementing these, taking inspiration from the surrounding code since i'm a rust n00b.

Test Plan:
```
cargo build
cargo test channel_reestablish
```
output:
```
running 3 tests
test ln::msgs::tests::encoding_channel_reestablish_with_secret ... ok
test ln::msgs::tests::decode_channel_reestablish_bad_length ... ok
test ln::msgs::tests::encoding_channel_reestablish_no_secret ... ok

test result: ok. 3 passed; 0 failed; 0 ignored; 0 measured; 14 filtered out
```

fd141bbed2 [Error] rename msg field to action 
this was a TODO and also briefly discussed in https://github.com/rust-bitcoin/rust-lightning/pull/43#pullrequestreview-135649551

I'm not fully sure how to remove the `Option`, and make it completely required. Would love suggestions. So, have omitted that for now. Plus, better to make smaller, incremental changes.

Test Plan:
`cargo build`
`cargo test`

should at least kinda sorta work now.
