b54f8a1b97 kvdb+channeldb: create ExtendedBackend interface to allow rich tx logic 
This commit adds the ExtendedBackend interface which is an extension to
the walletdb.DB interface. This paves the way to using etcd.db.View and
etcd.db.Update in the global View and Update functions without much code
rewrite.

02f9d91e49 kvdb+etcd: only lock on bucket path mod revision for reads and writes 
This commit reduces the compare set size the STM will submit in
transactions by adding only the bucket keys along the bucket path to a
specific lock set. This lock set then used to filter the read set,
effectively removing all read only keys from the transaction predicate
that are not bucket keys.
By tracking if a read-write tx actually changes something, we can also
"bump" the mod revision of the bucket keys.
With this trick we essentially implement a read-write lock for our
bucket structure greatly reducing transaction processing time.

9d57c1a6b4 lncfg: add configuration for user specified db backend 
This commit extends lncfg to support user specified database backend.
This supports configuration for both bolt and etcd (while only allowing
one or the other).

137dee04e8 channeldb+kvdb: an extended STM on top of etcd clientv3 
This commit adds an extended STM, similar to what available in etcd's
clientv3 module. This incarnation of said STM supports additional
features, like positioning in key intervals while taking into account
deletes and writes as well. This is a preliminary work to support all
features of the kvdb interface.

peer: fix struct alignment 
Integers used atomically MUST be aligned properly, otherwise the
sync library will crash on purpose. Therefore non-aligned struct
members must come later.

channeldb+htlcswitch: don't use fastsha256 in tests 
The btcsuite/fastsha256 registers itself in the crypto package of
golang as a replacement for sha256. This causes problems in TLS1.3
connections that require the hash implementations to be serializable
and results in the "tls: internal error: failed to clone hash" error.
By removing all uses of the library we fix that error.

htlcswitch: sync link hand-off 
This commit extends the link with a new synchronous delivery point for
local UpdateAddHTLC messages. The switch method SendHTLC is updated to
use this delivery point and thereby becomes a synchronous call.

For MPP payments, synchronous hand-off is important. Otherwise the next
pathfinding round could start without the channel balance updated yet.
