This contains significant rebase / merge / testing work by Naut
<lbrynaut@protonmail.com>, Anthony Fieroni <bvbfan@abv.bg> and Brannon
King <countprimes@gmail.com>.
Instead of adding BerkeleyEnvironment objects permanently to the g_dbenvs map,
use reference counted shared pointers and remove map entries when the last
BerkeleyEnvironment reference goes out of scope.
This change was requested by Matt Corallo <git@bluematt.me> and makes code that
sets up mock databases cleaner. The mock database environment will now go out
of scope and be reset on destruction so there is no need to call
BerkeleyEnvironment::Reset() during wallet construction to clear out prior
state.
This change does affect bitcoin behavior slightly. On startup, instead of same
wallet environments staying open throughout VerifyWallets() and OpenWallets()
calls, VerifyWallets() will open and close an environment once for each wallet,
and OpenWallets() will create its own environment(s) later.

Adds a ReloadDbEnv function to BerkeleyEnvironment in order to close all Db
instances, closes the environment, resets it, and then reopens
the BerkeleyEnvironment.
Also adds a ReloadDbEnv function to BerkeleyDatabase that calls
BerkeleyEnvironment's ReloadDbEnv.

This moves the Dock icon click reaction code to the common place and
allows some cleanup in obj_c code.
According to the Apple's docs `class_replaceMethod` behaves as
`class_addMethod`, if the method identified by name does not yet exist;
or as `method_setImplementation`, if it does exist.

0.17 branch doesn't include #12493 which changed encryptwallet behavior. For that
reason the test is adjusted.

Refactor the process of PSBTInput signing to enforce the invariant that
a PSBTInput always has _either_ a witness_utxo or a non_witness_utxo,
never both.
This simplifies the logic of SignPSBTInput slightly, since it no longer
has to deal with the "both" case. When calling it, we now give it, in
order of preference: (1) whichever of the utxo fields was already
present in the PSBT we received, or (2) if neither, the
non_witness_utxo field, which is just a copy of the input transaction,
which we get from the wallet.
SignPSBTInput no longer has to remove one of the two fields; instead, it
will check if we have a witness signature, and if so, it will replace
the non_witness_utxo with the witness_utxo (which is smaller, as it is
just a copy of the output being spent.)
Add PSBTInput::IsSane checks in two more places, which checks for
both utxo fields being present; we will now give an RPC error early on
if we are supplied such a malformed PSBT to fill in.
Also add a check to FillPSBT, to avoid touching any input that is
already signed. (This is now redundant, since we should no longer
potentially harm an already-signed input, but it's harmless.)

Github-Pull: #14588
Remove redundant arguments to SignPSBTInput -- since it needs several
bits of the PartiallySignedTransaction, pass in a reference instead of
doing it piecemeal. This saves us having to pass in both a PSBTInput and
its index, as well as having to pass in the CTransaction. Also avoid
redundantly passing the sighash_type, which is contained in the
PSBTInput already.

Refactor out a "PSBTInputSigned" function to check if a PSBT is signed,
for use in subsequent commits.
Also improve a related comment.

48fef5ebae gui: Fix race in WalletModel::pollBalanceChanged (Russell Yanofsky)

Pull request description:
These are not blockers for the 0.19.1 release, as per [IRC discussion this morning](http://www.erisian.com.au/bitcoin-core-dev/log-2020-02-27.html#l-331), doesn't look like there will be an rc3. This PR can collect further backports for the 0.19 branch.

Poll function was wrongly setting cached height to the current chain height
instead of the chain height at the time of polling.
This bug could cause balances to appear out of date, and was first introduced
a0704a8996 (r378452145)
Before that commit, there wasn't a problem because cs_main was held during the
poll update.
Currently, the problem should be rare. But if
8937d99ce81a27ae5e1012a28323c0e26d89c50b from #17954 were merged, the problem
would get worse, because the wrong cachedNumBlocks value would be set if the
wallet was polled in the interval between a block being connected and it
processing the BlockConnected notification.
MarcoFalke <falke.marco@gmail.com> also points out that a0704a8996 could lead
to GUI hangs as well, because previously the pollBalanceChanged method, which
runs on the GUI thread, would only make a nonblocking TRY_LOCK(cs_main) call,
but after could make blocking LOCK(cs_main) calls, potentially locking up the
GUI.
Thanks to John Newbery <john@johnnewbery.com> for finding this bug this while
reviewing https://github.com/bitcoin/bitcoin/pull/17954.
