lnwire: remove MaxPayloadLength from Message interface
Removes the MaxPayloadLength function from the Message interface
and checks that each message payload is not greater than MaxMsgBody.
Since all messages are now allowed to be 65535 bytes in size, the
MaxPayloadLength is no longer needed.

lnwire: convert the delivery addr in [Open+Accept]Channel to a TLV type in ExtraData
In this commit, we convert the delivery address in the open and accept
channel methods to be a TLV type. This works as an "empty" delivery
address is encoded using a two zero bytes (uint16 length zero), and a
tlv type of 0 is encoded in the same manner (byte for type, byte for
zero length). This change allows us to easily extend these messages in
the future, in a uniform manner.

When decoding the message we snip the bytes from the read TLV data.
Similarly, when encoding we concatenate the TLV record for the shutdown
script with the rest of the TLV data.

lnwire: update quickcheck tests, use constant for Error

multi: update unit tests to pass deep equal assertions with messages

In this commit, we update a series of unit tests in the code base to now
pass due to the new wire message encode/decode logic. In many instances,
we'll now manually set the extra bytes to an empty byte slice to avoid
comparisons that fail due to one message having an empty byte slice and
the other having a nil pointer.

lnwire: create new ExtraOpaqueData type for parsing TLV extensions
In this commit, we create a new `ExtraOpaqueData` based on the field
with the same name that's present in all the announcement related
messages. In later commits, we'll embed this new type in each message,
so we'll have a generic way to add/parse TLV extensions from messages.

discovery+lnwire: remove embedding within ReplyChannelRange
In order to prep for allowing TLV extensions for the `ReplyChannelRange`
and `QueryChannelRange` messages, we'll need to remove the struct
embedding as is. If we don't remove this, then we'll attempt to decode
TLV extensions from both the embedded and outer struct.

All relevant call sites have been updated to reflect this minor change.

lnwire: add new RequiresFeature method
In this commit, we add a new RequiresFeature method to the feature
vector struct. This method allows us to check if the set of features
we're examining *require* that the even portion of a bit pair be set.
This can be used to check if new behavior should be allowed (after we
flip new bits to be required) for existing contexts.

discovery: rate limit incoming channel updates
This change was largely motivated by an increase in high disk usage as a
result of channel update spam. With an in memory graph, this would've
gone mostly undetected except for the increased bandwidth usage, which
this doesn't aim to solve yet. To minimize the effects to disks, we
begin to rate limit channel updates in two ways. Keep alive updates,
those which only increase their timestamps to signal liveliness, are now
limited to one per lnd's rebroadcast interval (current default of 24H).
Non keep alive updates are now limited to one per block per direction.

44555a70ed lnwire: fix decoding for initial zero sid
This fixes a decoding error when the list of short channel ids within a
QueryShortChanIDs message started with a zero sid.

BOLT-0007 specifies that lists of short channel ids should be sorted in
ascending order. Previously, this was checked within lnwire by comparing
two consecutive sids in the list, starting at the empty (zero) sid.

This meant that a list that started with a zero sid couldn't be decoded
since the first element would _not_ be greater than the last one
(namely: also zero).

Given that one can only check for ordering starting at the second
element, we add a check to ensure the proper behavior.

A unit test is also added to ensure no future regressions on this
behavior.

lnwire: explicitly handle empty list when encoding short chan IDs
Before this commit, both writing and reading an encoded empty set of
short channel IDs from the wire would fail. Prior to this commit, we
treated decoding an empty set as a caller error, and failed to write out
the zlib encoding of an empty set in a way that us and the other
implementations were able to read.

To fix this, rather than giving zlib an empty buffer to write out (which
results in an encoding with the zlib header data and the rest), we just
write a blank slice. When decoding, if we have an empty query body, then
we'll return a `nil` slice.

With the above changes, we'll now always write out an empty short
channel ID set as:
```
0001 (1 byte follows) || <encoding_type>
```

A new test has also been added to exercise this case for both known
encoding types.

feature: add new feature pkg to manage feature sets
This commit introduces a feature.Manager, which derives feature vectors
for various contexts within the daemon. The sets can be described via a
staticly compiled format, which makes any runtime adjustments to the
feature sets when the manager is initialized.

routing: use unified policy for path finding
In this commit we change path finding to no longer consider all channels
between a pair of nodes individually. We assume that nodes forward
non-strict and when we attempt a connection between two nodes, we don't
want to try multiple channels because their policies may not be identical.
Having distinct policies for channel to the same peer is against the
recommendation in the spec, but it happens in the wild. Especially since
we recently changed the default cltv delta value.

What this commit introduces is a unified policy. This can be looked upon
as the greatest common denominator of all policies and should maximize
the probability of getting the payment forwarded.
