multi: partition lnwire.ChanUpdateFlag into ChannelFlags and MessageFlags
In this commit:

* we partition lnwire.ChanUpdateFlag into two (ChanUpdateChanFlags and
ChanUpdateMsgFlags), from a uint16 to a pair of uint8's

* we rename the ChannelUpdate.Flags to ChannelFlags and add an
additional MessageFlags field, which will be used to indicate the
presence of the optional field HtlcMaximumMsat within the ChannelUpdate.

* we partition ChannelEdgePolicy.Flags into message and channel flags.
This change corresponds to the partitioning of the ChannelUpdate's Flags
field into MessageFlags and ChannelFlags.

0b10f4c4d8 lnwire: when reading node aliases, properly check validity
In this commit, we ensure that when we read node aliases from the wire,
we ensure that they're valid. Before this commit, we would read the raw
bytes without checking for validity which could result in us writing in
invalid node alias to disk. We've fixed this, and also updated the
quickcheck tests to generate valid strings.

lnwire: export ReadElements and WriteElements
In this commit, we export the ReadElements and WriteElements functions.
We do this as exporting these functions makes it possible for outside
packages to define serializations which use the BOLT 1.0 wire format.

peer: don't d/c peer if we encounter lnwire.ErrUnknownAddrType
In this commit, we fix a minor deviation in our implementation from the
specification. Before if we encountered an unknown error type, we would
disconnect the peer. Instead, we’ll now just continue along parsing the
remainder of the messages. This was flared up recently by some
c-lightning related incompatibilities that emerged on main net.

lnwire: replace instances of *btcec.PublicKey with [33]byte in ann messages
In this commit, we replace all instances of *btcec.PublicKey within the
announcement messages with a simple [33]byte. We do this as usually we
don’t need to immediately validate an announcement, therefore we can
avoid the scalar multiplications during decoding.

lnwire: add new FundingFlag type for OpenChannel
In this commit we add a new type to the lnwire package: FundingFlag.
This type will serve as an enum to describe the possible flags that can
be used within the ChannelFlags field in the OpenChannel struct.

We also define the first assigned flag: FFAnnounceChannel, which
indicates if the initiator of the funding flow wishes to announce the
channel to the greater network.

lnwire: properly encode/decode addrs in NodeAnnouncement msg
This commit fixes an existing deviation in the way we encode+decode the
addresses within the NodeAnnouncement message with that of the
specification. Prior to this commit, we would encode the _number_ of
addresses, rather than the number of bytes it takes to encode all the
addresses.

In this commit, we fix this mistake by properly writing out the total
number of bytes, modifying our parsing to take account of this new
encoding.

d97575d6d2 lnwire: ensure that addrs in ClosedSigned are below 35 bytes
This is a very simple bug that go-fuzz found. If length of an address
within CloseSigned is greater than 34, a runtime error: slice bounds out
of range happens. An error should be returned instead.

lnwire: introduce new lnwire.MilliSatoshi type
This commit adds a new type to the lnwire package: MilliSatoshi. A
milli-satoshi is simply 1/1000th of a satoshi, and will be used for all
internal accounting when sending payments, calculating fees, updating
commitment state, etc. Two helper methods are added: ToBTC(), and
ToSatoshis() to make manipulation of the values easy.

lnwire: create distinct type for UpdateFailHTLC failure reason
This commit creates a distint type for the opaque failure reason within

variable length byte slice within the protocol and therefore requires a
length prefix in order to serialize/deserialize properly.

lnwire: morph CancelHTLC into UpdateFailHTLC, remove HTLCAddReject
This commit morphs the prior CancelHTLC into the new UpdateFailHTLC
message and also gets rid of the obsolete HLTCAddReject message while
we’re at it.

The primary change from the CancelHTLC message to the UpdateFailHTLC
message is that the CancelReason is now simply called Reason and that
it’s now an opaque encrypted set of bytes. With this update the failure
messages are now more flexible (they can even carry new
ChannelUpdate’s) and also don’t reveal the exact cause of failure to
intermediate nodes.
