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

contractcourt+lnwallet: use state num instead of commit height when
outdated local state

This commit fixes a bug that would cause us to not sweep our local
output in case we force closed, then lost state or attempted recovery.
The reason being that we would use or local commit height when deriving
our scripts, which would be incorrect. Instead we use the extracted
state number to derive the correct scripts, allowing us to sweep the
output.

Allthough being an unlikely scenario, we would leave money on chain in
this case without any warning (since we would just end up with an empty
delay script) and forget about the spend.

lnwallet/channel: correct dust calculation on incoming HTLC
Similar to the previous commit, we fix a bug resulting in the wrong
commit weight being calculated when an HTLC just above the remote's
duslimit was added from the remote. This was a result of using the
successFee instead of the timeoutFee when checking whether it was dust,
making us consider it dust when it shouldn't have been.

lnwallet/channel: correct dust calculation on outgoing HTLC
In this commit we fix a bug resulting in the wrong commit weight being
calculated when an HTLC just below the remote's duslimit was added. This
was a result of using the timeoutFee instead of the successFee when
checking whether it was dust, making us consider it non-dust when it
should have been.

chanfunding: assure logic for high-fee
Without this change the high-fee logic is never tested as it is instead caught by the dust-output logic. This change uses a higher fee rate to ensure an output value above the dust limit, while still spending 20% on fees.

chanfunding: assure logic for dust output
Without this change the fee for the test case is above 20% and hence the error could be caught by the high-fee logic instead.

multi: add max local csv config option
To allow nodes more control over the amount of time that their funds
will be locked up, we add a MaxLocalCSVDelay option which sets the
maximum csv delay we will accept for all channels. We default to the
existing constant of 10000, and set a sane minimum on this value so that
clients cannot set unreasonably low maximum csv delays which will result
in their node rejecting all channels.

btcwallet: return chain best timestamp while backend is syncing
A while back, changes were made to the wallet such that it waits for the
backend to be synced before beginning to store the latest 10,000 blocks
of the chain. This inherently broke sync progress implementations based
on the best_header_timestamp result from the GetInfo RPC for
neutrino-based nodes as the wallet is no longer tracking all blocks in
the chain. To work around this, we now make sure to return the backend's
best header timestamp instead of the wallet's, allowing said sync
progress implementations to work again.

f5fb64e552 add new max channel size config option
- let users specify their MAXIMUM WUMBO with new config option which sets the maximum channel size lnd will accept
- current implementation is a simple check by the fundingManager rather than anything to do with the ChannelAcceptor
- Add test cases which verify that maximum channel limit is respected for wumbo/non-wumbo channels
- use --maxchansize 0 value to distinguish set/unset config. If user sets max value to 0 it will not do anything as 0 is currently used to indicate to the funding manager that the limit should not be enforced. This seems justifiable since --maxchansize=0 doesn't seem to make sense at first glance.
- add integration test case to ensure that config parsing and valiation is proper. I simplified the funding managers check electing to rely on config.go to correctly parse and set up either i) non wumbo default limit of 0.16 BTC OR ii) wumbo default soft limit of 10 BTC

lnwallet/test: make use of test htlcs explicit
Previously whether or not to add test htlcs was implictly controlled by
a nil value of the HtlcDescs test parameter. With the conversion to
json, that nil value got lost.

The reason that the test still passed is because with the fee rate of
the no-htlc test case, the htlcs were trimmed. Also because in the test
json, balances are specified after applying htlcs, the test didn't fail
with a mismatching balance.

multi: add labels to lnd native transactions
Follow up labelling of external transactions with labels for the
transaction types we create within lnd. Since these labels will live
a life of string matching, a version number and rigid format is added
so that string matching is less painful. We start out with channel ID,
where available, and a transaction "type". External labels, added in a
previous PR, are not updated to this new versioned label because they
are not lnd-initiated transactions. Label matching can check this case,
then check for a version number.

Previously, we could sign a pending commitment for the remote party,

removed at the pending commitment height. This commit fixes that to
look up whether the update under the unsigned acked updates key is
present on the pending commitment or not and appropriately set
the remove commit heights.

2149157d49 channeldb: filter out unsigned acked updates in AdvanceCommitChainTail
This commit moves the deletion of all updates under the unsigned
acked updates key from AppendRemoteCommitChain to
AdvanceCommitChainTail. This is done because if we went down after
signing for these updates but before receiving a revocation, we would
incorrectly reject their commitment signature:

Alice                Bob
      -----add----->
      -----sig----->
      <----rev------
      <----sig------
      -----rev----->
      <----fail-----
      <----sig------
      -----rev----->
      -----sig----->
      *reconnect*
      <----rev------
      <----add------
      x----sig------

It is also important to note that filtering is required when we
receive a revocation to ensure that we aren't erroneously deleting
remote updates. Take the following state transitions:

 Alice                Bob
       -----add----->
       -----sig----->
       <----rev------
       <----sig------
       -----rev----->
       -----add----->
       -----sig----->
       <----fail-----
       <----sig------
       -----rev-----> (alice stores updates here)
       <----rev------

In the above case, if Alice deleted all updates rather than filtering
when receiving the final revocation from Bob, then Alice would have
to force close the channel due to missing updates. Since Alice hasn't
signed for any of the unsigned acked updates, she should not filter any
of them out.
