In this commit, we check that the extra bytes appended to gossip
messages contain valid TLV streams. We do this here for:
- channel_announcement
- channel_announcement_2
- channel_update
- channel_update_2
- node_announcement
This is in preparation for the SQL version of the graph store which will
normalise TLV streams at persistence time.
Find and replace all nolint instances refering to the `lll` linter and
replace with `ll` which is the name of our custom version of the `lll`
linter which can be used to ignore log lines during linting.
The next commit will do the configuration of the custom linter and
disable the default one.
Add the TrueBoolean type along with its Record method. Also update the
Millisatoshi type with a Record method. Both of these will be used in an
upcoming commit which adjusts a mission control migration to use pure
TLV types.
