a14f25830e htlcswitch: remove redudant variables
Because processing of onion blob have been moved in another place we
could get rid of the variables which are not needed any more.

NOTE: pendingBatch have been replaced with batchCounter variable, but
it should be removed at all, because number of pending batch updates
might be counted by the state machine itself.

0e2209cb12 htlcswitch: move onion blob processing
Step №4 in making htlcManager (aka channelLink) testable:

This step consist of two:
1. Start using the hop iterator abstraction, the concrete
implementation of which will be added later, basically it will we the
same sphinx onion packet processor, but wrapped in hop iterator
abstraction.

2. The RevokAndAck processing part have been replaced by the
"processLockedInHtlcs" function which implement the same logic, but make
it a bit simpler.

Such changes will allow as to get rid of the the unnecessary variables.

de01721aed htlcswitch: add hop iterator
Short: such abstraction give as ability to test the channel link in the
future.

Long: hop iterator represents the entity which is be able to give payment
route hop by hop. This interface will be used to have an abstraction
over the algorithm which we use to determine the next hope in htlc route
and also helps the unit test to create mock representation of such
algorithm which uses simple array of hops.

db30571efe htlcswitch: start using config in channel link

Apply the channel link config inside the channel link itself.

2eea76375c htlcswitch: make channel link implements interface
Step №2 in making htlcManager (aka channelLink) testable:
Implement the ChannelLink interface which is needed to use it in pair
with htlc switch. With this commit channel link impelements interface,
but isn't able to operate properly yet.

7f572fc155 htlcswitch: add channel link config
Step №1 in making htlcManager (aka channelLink) testable:
Start use config which will allow as mock/stub external subsystems.

0de4ea2712 htlcswitch: copy the initial representation of htlc manager
In this commit all initial code which will be transformed into channel
link have been added. Rather than changing the in the same commit is
better to create the standalone commit, in order to see the changes
which have been applied to relocated code.
