routing: check for empty hops list
This commit fixes a crash that could be triggered by sending an empty
hop list to the SendToRoute rpc.

routing: prune channels unidirectional
In this commit we introduce pruning of channel edges instead of channels.
Channel failures apply to a single direction and it is unnecessarily
restricting to prune both directions.

routing: remove route hop maps
Hop maps were used in a test to verify the population of the hop map
itself and further only in a single function (getFailedChannelID).
Rewrote that function and removed the hop maps completely.

routing: fix node ordering in test graph
There is the general assumption that channel edge policy nodes are
ordered such that the node1 pubkey is smaller than the key of node 2. In
the test graph, this assumption didn't hold. This commit fixes the test
graph and also adds a check to prevent this from happening again.

routing/pathfind test: add TestPathSourceEdgesBandwidth
This commit adds a new test that checks that the bandwidth hints are
considered correclty for local channels, and that disable flags are
ignored in this case.

routing/pathfind: pass ignore disable flags for local channels
To decouple our own path finding from the graph state, we don't consider
the disable bit when attempting to use local channels. Instead the
bandwidth hints will be zero for local inactive channels.

We alos modify the unit test to check that the disable flag is ignored
for local edges.

routing: define graphParams and restrictParams
To avoid the findPath parameter list getting out of hand, we define new
structs that wraps the mandatory and optional parameters to findPath.

routing: make routing retry behaviour consistent
Fixes the following issues:
- If the channel update of FailFeeInsufficient contains an invalid channel
  update, it is not possible to properly add to the failed channels set.
- FailAmountBelowMinimum may apply a channel update, but does not retry.
- FailIncorrectCltvExpiry immediately prunes the vertex without
  trying one more time.

In this commit, the logic for all three policy related errors is
aligned.

htlcswitch+routing: implement expiry_too_far failure
In this commit we add a check to HtlcSatifiesPolicy to verify that the
time lock for the outgoing htlc that is requested in the onion packet
isn't too far in the future.

Without this check, anyone could force an unreasonably long time lock on
the forwarding node.

lnrpc+routing: fix issues with missing data in unmarshallRoute
In this commit the dependency of unmarshallRoute on edge policies being
available is removed. Edge policies may be unknown and reported as nil.
SendToRoute does not need the policies, but it does need pubkeys of the
route hops. In this commit, unmarshallRoute is modified so that it
takes the pubkeys from edgeInfo instead of channelEdgePolicy.

In addition to this, the route structure is simplified. No more connection
to the database at that point. Fees are determined based on incoming and
outgoing amounts.

discovery+routing: move validation logic to routing package
Previously, gossiper was the only object that validated channel
updates. Because updates can also be received as part of a
failed payment session in the routing package, validation logic
needs to be available there too. Gossiper already depends on
routing and having routing call the validation logic inside
gossiper would be a circular dependency. Therefore the validation
was moved to routing.

routing: return ErrRejected if found in reject cache
We make sure to return an error other than ErrIgnored, as ErrIgnored is
expected to only be returned for updates where we already have the
necessary information in the database.

In case of a channel ID found in the rejectCache, there was a
possibility that we had rejected an invalid update for this channel
earlier, and when attempting to add the current update we wouldn't
distinguish the failure to add from an outdated/ignored update.
