7c85363ef6 config: Add norest config for disabling REST API
This commit adds a new config `norest` for disabling the REST API.
This is useful in cases where it is not needed (i.e lnd running on
mobile devices).

htlcswitch: cap fee updates to max fee allocation
In this commit, we begin to enforce a maximum channel commitment fee for
channel initiators when attempting to update their commitment fee. Now,
if the new commitment fee happens to exceed their maximum, then a fee
update of the maximum fee allocation will be proposed instead if needed.

A default of up to 50% of the channel initiator's balance is enforced
for the maximum channel commitment fee. It can be modified through the
`--max-channel-fee-allocation` CLI flag.

config: add new legacy protocol build tag protected sub-config for legacy onion
In this commit, we add a new build tag protected sub-config for legacy
protocol features. The goal of this addition is to be able to default to
new feature within lnd, but expose hooks at the config level to allow
integration tests to force the old behavior to ensure that we're able to
support both the old+new versions.

htlcswitch+config+server: Adds a rejecthtlc flag that disables forwarded
htlcs

config: Adding RejectHTLC field in config struct

This commit adds a RejectHTLC field in the config struct in config.go.
This allows the user to run lnd as a node that does not accept onward
HTLCs.

htlcswitch/switch: Adding a field RejectHTLC to the switch config

This commit adds a field RejectHTLC to the switch config. When the
switch receives an HTLC it will check this flag and if the HTLC is not
from the source hop, the HTLC will be rejected.

htlcswitch/switch: adding check for RejectHTLC flag and incomingChanID

This commit adds a check when receiving UpdateAddHTLC. The check looks
for the RejectHTLC flag set and whether the HTLC is from the sourceHop
(the local switch). If the HTLC is not from the sourceHop, then we
reject the HTLC and return a FailChannelDisabled error.

server: adding RejectHTLC field to initialization of switch

lnd_test: adding test for RejectHTLC

This commit adds a test which tests that a node with the --rejecthtlc
flag will reject any onward HTLCs but still can receive direct HTLCs and
can send HTLCs.

multi: remove debug invoices
Debug invoices are rarely used nowadays, but keep asking for maintenance
every time refactoring in primarily the invoice registry occurs. We have
passed the cost/benefit tipping point, so therefore the debug invoice
concept is removed in this commit.

Previously the debughtlc flag also controlled whether hodl masks were
active. It is safe to remove that additional condition because the hodl
masks are still guarded by the dev build tag.

config+server: add ignore-historical-filters CLI option
This commit adds the ignore-historical-filters CLI option, initially
defaulting to false. Users may use this option to prevent lnd from doing
historical gossip dumps to peers that set their `gossip_timestamp_range`
in the past. Enabling this option will result in lower bandwidth and
memory consumption. Down the road the plan is to make this default to
true.

multi: only allow specifying towers to TowerClient through RPC
With the introduction of the WatchtowerClient RPC subserver, the lnd
configuration flag to specify private watchtowers for the client is no
longer needed and can lead to confusion upon users. Therefore, we remove
the flag completely, and only rely on the watchtower client being active
through a new --wtclient.active flag.

This commit fixes a bug where it was impossible to run lnd in litecoin's

conditional was always true when running lnd with `cfg.Litecoin.SimNet`

server: stagger initial reconnects
This commit adds optional jitter to our initial reconnection to our
persistent peers. Currently we will attempt reconnections to all peers
simultaneously, which results in large amount of contention as the
number of channels a node has grows.

We resolve this by adding a randomized delay between 0 and 30 seconds
for all persistent peers. This spreads out the load and contention to
resources such as the database, read/write pools, and memory
allocations. On my node, this allows to start up with about 80% of the
memory burst compared to the all-at-once approach.

This also has a second-order effect in better distributing messages sent
at constant intervals, such as pings. This reduces the concurrent jobs
submitted to the read and write pools at any given time, resulting in
better reuse of read/write buffers and fewer bursty allocation and
garbage collection cycles.

When Tor is enabled, this change allows manual hidden service

the loopback address. It also allows overriding this manually
for situations where the Tor daemon is running on another machine,
such as when using Whonix or OnionPi-like systems.

config+rpc: create new generalized dynamic sub rpc server config framework
In this commit, we add the glue infrastructure to make the sub RPC
server system work properly. Our high level goal is the following: using
only the lnrpc package (with no visibility into the sub RPC servers),
the RPC server is able to find, create, run, and manage the entire set
of present and future sub RPC servers. In order to achieve this, we use
the reflect package and build tags heavily to permit a loosely coupled
configuration parsing system for the sub RPC servers.

We start with a new `subRpcServerConfigs` struct which is _always_
present.  This struct has its own group, and will house a series of
sub-configs, one for each sub RPC server. Each sub-config is actually
gated behind a build flag, and can be used to allow users on the command
line or in the config to specify arguments related to the sub-server. If
the config isn't present, then we don't attempt to parse it at all, if
it is, then that means the RPC server has been registered, and we should
parse the contents of its config.

The `subRpcServerConfigs` struct has two main methods:
`PopulateDependancies` and `FetchConfig`. The `PopulateDependancies` is
used to dynamically locate and set the config fields for each new
sub-server. As the config may not actually have any fields (if the build
flag is off), we use the reflect pacakge to determine if things are
compiled in or not, then if so, we dynamically set each of the config
parameters. The `PopulateDependancies` method implements the
`lnrpc.SubServerConfigDispatcher` interface. Our goal is to allow sub
servers to look up their actual config in this main config struct. We
achieve this by using reflect to look up the target field _as if it were
a key in a map_. If the field is found, then we check if it has any
actual attributes (it won't if the build flag is off), if it is, then we
return it as we expect it to be populated already.
