Add more fields to channel acceptor response so that users can have more
fine grained control over their incoming channels. With our chained
acceptor, it is possible that we get inconsistent responses from
multiple chained acceptors. We create a conjugate repsponse from all the
set fields in our various responses, but fail if we get different, non-
zero responses from our various acceptors. Separate merge functions are
used per type so that we avoid unexpected outcomes comparing interfaces
(panic on comparing types that aren't comparable), with casting used
where applicable to avoid code duplication.
This commit moves and partially refactors the channel acceptor logic
added in c2a6c86e into the channel acceptor package. This allows us to
use the same logic in our unit tests as the rpcserver, rather than
needing to replicate it in unit tests.
Two changes are made to the existing implementation:
- Rather than having the Accept function run a closure, the closure
originally used in the rpcserver is moved directly into Accept
- The done channel used to signal client exit is moved into the acceptor
because the rpc server does not need knowledge of this detail (in
addition to other fields required for mocking the actual rpc).

Give the external subservers the possibility to also use their own
validator to check any macaroons attached to calls to their registered
gRPC URIs.
This allows them to have their own root key ID database and permission
entities.
When dealing with online events, we actually need to track our events
by peer, not by channel. All we need to track channels is to have a
set of online events for a peer which at least contain those events.
This change refactors chanfitness to track by peer.
We currently query the store for uptime and lifespan individually. As
we add more fields, we will need to add more queries with this design.
This change combines requests into a single channel infor request so
that we do not need to add unnecessary boilerplate going forward.
As a convenience method for users to look up what RPC method URIs exist
and what permissions they require, we add a new ListPermissions call
that simply returns all registered URIs (including internal and external
subservers) and their required permissions.
To make sure we can use the abandonchannel RPC for getting rid of
externally funded channels who's funding transaction was never
published, we allow the RPC to be used on non-dev builds for externally
funded and pending channels only.
This commit adds the same CORS functionality that's currently in the main gRPC proxy to the WalletUnlocker proxy. This ensures the CORS configuration is carried through all API endpoints
To avoid the scenario where the user tries to force close a channel too
early that was restored through SCB, we check the channel status in the
RPC server already. If a restored channel cannot connect to its peer and
mark it as local data loss the channel arbitrator would try to publish
the commitment TX it does not have and crash.
This commit removes the activeNetParams global in chainparams.go. This
is necessary to isolate code from the lnd package so we can import it
for use in tests, other projects, etc.
In this commit, we split the database storage into two classes: remote
and local data. If etcd isn't active, then everything is actually just
local though we use two pointers everywhere. If etcd is active, then
everything but the graph goes into the remote database.
