routing: avoid modifying AssumeChannelValid in unit tests
This produces a race condition when reading AssumeChannelValid from a
different goroutine. Instead we isolate the test cases and initial
AssumeChannelValid properly.

routing: dial back max concurrent block fetches
This commit reduces the number of concurrent validation operations the
router will perform when fully validating the channel graph. Reports
from several users indicate that GetInfo would hang for several minutes,
which is believed to be caused by attempting to validate massive amounts
of channels in parallel. This commit returns the limit back to its
original state before adding the batched gossip improvements.

We keep the 1000 concurrent validation request limit for
AssumeChannelValid, since we don't fetch blocks in that case. This
allows us to still keep the performance benefits on mobile/low-resource
devices.

routing: if MaxShardAmt is set, then use that as a ceiling for our splits
In this commit, we thread through the necessary state to allow users to
set a max shard amount. If this value is set, then this'll effectively
serve as a ceiling for all our split attempts. If we need to split,
we'll first try to use `paymentAmt/2`, if that's bigger than
`MaxShardAmt, then we'll use the latter instead.

Ideally in the future we have a dynamic way to automatically set both
the `MaxShardAmt` as well as `MaxParts` for users. Until then exposing
these two new fields will allow us to experiment with setting them
automatically using the RPC interface, and also give users a bit more
control over how we attempt to route payments, akin to coin control for
on-chain payments.

Fixes #4730

routing: add new TestPaymentAddrOnlyNoSplit test case
This test case ensures that we won't try to split payment if the dest
has the payment addr bit, but NOT the mpp optional/require bit.

routing: allow custom dest feature bits in integratedRoutingContext.testPayment
This is a preparatory commit for a new test to ensure that if a node
only has the TLV and payment addr feature bits, we don't try to split a
payment.

routing: move locking for ReportPaymentSuccess and ReportPaymentFailure
All of the other mission control exported functions acquire their locks
immediately, and do not lock in the subsequent unexported functions.
This commit moves the lock up for the report payment functions so that
mission control's config values are covered by this lock, in preparation
for allowing config to be updated at runtime. Moving this lock means
that we will hold the lock for the additional time it takes to store a
single result, AddResult, to the store.

kvdb: add timeout options for bbolt (#4787)
* mod: bump btcwallet version to accept db timeout

* btcwallet: add DBTimeOut in config

* kvdb: add database timeout option for bbolt

This commit adds a DBTimeout option in bbolt config. The relevant
functions walletdb.Open/Create are updated to use this config. In
addition, the bolt compacter also applies the new timeout option.

* channeldb: add DBTimeout in db options

This commit adds the DBTimeout option for channeldb. A new unit
test file is created to test the default options. In addition,
the params used in kvdb.Create inside channeldb_test is updated
with a DefaultDBTimeout value.

* contractcourt+routing: use DBTimeout in kvdb

This commit touches multiple test files in contractcourt and routing.
The call of function kvdb.Create and kvdb.Open are now updated with
the new param DBTimeout, using the default value kvdb.DefaultDBTimeout.

* lncfg: add DBTimeout option in db config

The DBTimeout option is added to db config. A new unit test is
added to check the default DB config is created as expected.

* migration: add DBTimeout param in kvdb.Create/kvdb.Open

* keychain: update tests to use DBTimeout param

* htlcswitch+chainreg: add DBTimeout option

* macaroons: support DBTimeout config in creation

This commit adds the DBTimeout during the creation of macaroons.db.
The usage of kvdb.Create and kvdb.Open in its tests are updated with
a timeout value using kvdb.DefaultDBTimeout.

* walletunlocker: add dbTimeout option in UnlockerService

This commit adds a new param, dbTimeout, during the creation of
UnlockerService. This param is then passed to wallet.NewLoader
inside various service calls, specifying a timeout value to be
used when opening the bbolt. In addition, the macaroonService
is also called with this dbTimeout param.

* watchtower/wtdb: add dbTimeout param during creation

This commit adds the dbTimeout param for the creation of both
watchtower.db and wtclient.db.

* multi: add db timeout param for walletdb.Create

This commit adds the db timeout param for the function call
walletdb.Create. It touches only the test files found in chainntnfs,
lnwallet, and routing.

* lnd: pass DBTimeout config to relevant services

This commit enables lnd to pass the DBTimeout config to the following
services/config/functions,
  - chainControlConfig
  - walletunlocker
  - wallet.NewLoader
  - macaroons
  - watchtower
In addition, the usage of wallet.Create is updated too.

* sample-config: add dbtimeout option

routing+lnrpc: extend BuildRoute to accept raw payAddr
In this commit, we extend the `BuildRoute` method and RPC on the router
sub-server to accept a raw payment address which will be included as
part of an MPP payload for the finla hop. This change actually also
allows users to craft their own MPP paths using BuildRoute+SendToRoute.
Our primary goal however, was to fix some broken itests since we now
require the payAddr to be present for ALL payments other than key send
payments.

routing/router: increase validation barrier size to 1000
This allows for a 1000 different persistent operations to proceed
concurrently. Now that we are batching operations at the db level, the
average number of outstanding requests will be higher since the commit
latency has increased. To compensate, we allow for more outstanding
requests to keep the router busy while batches are constructed.

multi: enforce routing.MinCLTVDelta=18 for invoices + chanupd
This commit clamps all user-chosen CLTVs in LND to be at least 18, which
is the new conservative value used in the sepc. This minimum is applied
uniformly to forwarding CLTV deltas (via channel updates) as well as
final CLTV deltas for new invoices.
