lnwire: add a HtlcSigs field to the CommitSig message
This commit adds a new field to the CommitSig message: HtlcSigs. This
new field will house signatures for each of the HTLC’s on the newly
created commitment state. This addition allows us to implement the new
commitment transaction structure outlined within the specification
which modifies HTLC’s such that the claiming process is now a two-phase
process. The first state transitions an HTLC to the delay+claim state,
and the second state (after the delay has passed) allows the
broadcaster of the commitment transaction to sweep the HTLC’s.

Fixes #61.

lnwire: add a case for a slice of signatures to readElement/writeElement
This commit modifies the readElement and writeElement functions to add
the capability of reading/writing a slice of btcec.Signature. This new
case is required for the upcoming commit which will modify the
CommitSig message to include a field which houses signatures of reach
HTLC on the commitment transaction.

lnwire: add new single funder messages from specification
This commit adds the new set of single funder messages from the
specification. As a result, after this commit and a follow up, all of
our messages will directly line up with those that are detailed within
the specification.

The new set of funding messages are very similar to our prior ones,
aside from the main difference of the addition of several channel level
constraints that give nodes control over their exposure, throughput,
and other values.

lnwire: modify RevokeAndAck to remove NextRevocationHash
This commit modifies the RevokeAndAck message in order to bring it more
in line with the current draft of the specification. The prior version
was based on a version that used a revocation hash for HTLC’s and a
revocation key for commitment outputs. The current commitment design
uses revocation keys uniformly throughout.

lnwire: remove deprecated single funding wire messages
This commit removes the original single funder wire messages as they’ve
now been deprecated by the new commitment and HTLC structure within the
latest draft of the specification.

79b8d26b1a htlcswitch+router+server: handle payment error topology updates
In previous commits we have intoduced the onion errors. Some of this
errors include lnwire.ChannelUpdate message. In order to change
topology accordingly to the received error, from nodes where failure
have occured, we have to propogate the update to the router subsystem.

2d378b3280 htlcswitch+router: add onion error obfuscation
Within the network, it's important that when an HTLC forwarding failure
occurs, the recipient is notified in a timely manner in order to ensure
that errors are graceful and not unknown. For that reason with
accordance to BOLT №4 onion failure obfuscation have been added.

98956bc2fe lnwire: add specification onion errors
In this commit onion routing error from BOLT#4 have been added, the
initial error construction have been splitted on two parts: The first
part which contains the actual data will reside inside the lnwire
package because it contains all necessary function to decode/encode
the data. The second part obfuscation and hmac checking will resides
inside the lighting-onion package because it requires the key
generation.

funding: avoid dereferencing a nil localDiscoverySignal
This commit fixes a possible panic within the funding manger’s workflow
for pending channels. We now ensure that the local discovery signal
retrieved from the localDiscoverySignals map is always non-nil.
Otherwise, we risk a server panic in the case that a node retransmits
the FundingLocked message after a channel has been fully processed, or
even just sends a FundingLocked message for a non-existent channel.

352461d551 config: add regtest support to lnd
Support for regtest allows us to create integration tests to verify
interoperability with other implementations. This seems to work, and
allows to connect to `btcd` and indirectly to `bitcoind` so we can run
lnd on the same network as eclair and c-lightning.

For details about my integration framework check this repo:

test: ensure the WaitForBlockchainSync grouting always exits
This commit fixes a minor bug in the goroutine that’s launched to check
the sync status of a particular node. Previously, the goroutine could
end up infinitely stuck on a send as once the chain has been detected
as synced, it didn't exit.

We fix this now by ensure that the goroutine always terminates after
the initial notification to the caller. Additionally, we not ensure
that both the internal and exterior goroutine are both reading off of
the peer’s quit channel.

build: create parallel travis builds to isolate race condition tests
This commit modifies the travis build script, and our local test script
to ensure that the race condition builds are conducted in a parallel
build. After this commit two travis builds will be kicked off for each
push/commit: one that runs the race condition tests in isolation, and
another that runs the integration tests then the coverage tests.

In order to do the above cleanly, the integration tests are now guarded
behind a build flag. In order to run the integration tests, one now
needs to specify the `-tags rpctest` flag when running the `go test`
command.

htlcswitch: restore the ability to properly handle debughtlc recv's
This commit fixes a regression introduce in the prior commit which
added full verification of the per-hop payloads to the ChannelLink
interface. When this was initially implemented, the added checks
weren’t guarded on the existence of debughtlc’s. As a result,
debughtlc’s would be rejected as they don’t match the expected invoice
value.

This commit fixes that issue by only checking the hop payload if debug
HTLC mode isn’t on.
