720d9e8 [Wallet] always show help-line of wallet encryption calls (Jonas Schnelli)

Pull request description:

  We do currently show/hide the wallet encryption RPC calls from the help if the current wallet.
  In case of an encrypted wallet, `encryptwallet` is hidden and `walletpassphrasechange`, `walletpassphrasechange` and `walletlock` do appear in the help.

  This is no longer ideal in case of multiwallet due to the fact that one may want help infos in order to target a specific wallet.

  IMO its preferable to have a static help screen (show everything always). The currently show/hidden calls do handle the possible invalid encryption-state fine.

  Fixes #11588

Pull request description:

  I think these are all the remaining Bitcoin Core v0.15 PRs in the wallet area that we don't have yet, and are useful to us.
  I've grouped them here since they are all pretty small, simple, and narrow-focused (on the wallet/rpcwallet files).

  This changeset is based on top of
  - [x] #2337

  as it keeps going with the multiwallet implementation, adding:
  - RPC endpoint support
  - `listwallets` RPC
  - wallet name in `getwalletinfo` RPC
  - `wallet_multiwallet.py` functional test

  As in some areas we are much closer to upstream, some of the commits needed adaptations (especially the functional tests). A couple of commits have been extended to include shield-related code.

  List of upstream PRs backported/adapted:

  - bitcoin#9906  : Disallow copy constructor CReserveKeys
  - bitcoin#9830  : Add safe flag to listunspent result
  - bitcoin#9993  : Initialize nRelockTime
  - bitcoin#10108 : ApproximateBestSubset should take inputs by reference, not value
  - bitcoin#10075 : Remove unused C++ code not covered by unit tests
  - bitcoin#10257 : Add test for getmemoryinfo
  - bitcoin#10295 : Move some WalletModel functions into CWallet
  - bitcoin#10500 : Avoid CWalletTx copies in GetAddressBalances and GetAddressGroupings
  - bitcoin#10522 : Remove unused variables
  - bitcoin#10816 : Properly forbid -salvagewallet and -zapwallettxes for multi wallet
  - bitcoin#10849 : Multiwallet: simplest endpoint support
  - bitcoin#9380  : Separate different uses of minimum fees (only dustRelayFee)
  - bitcoin#10817 : Redefine Dust and add a discard_rate (only first commit)
  - bitcoin#10883 : Rename -usewallet to -rpcwallet
  - bitcoin#10604 : Add listwallets RPC, include wallet name in getwalletinfo + tests
  - bitcoin#10893 : Avoid running multiwallet.py twice
  - bitcoin#10870 : Use wallet 0 in rpc console if running with multiple wallets
  - bitcoin#10931 : Fix misleading "method not found" multiwallet errors
  - bitcoin#10885 : Reject invalid wallets
  - bitcoin#11022 : Basic keypool topup
  - bitcoin#10976 : [MOVEONLY] Move some static functions out of wallet.h/cpp
  - bitcoin#11310 : Test listwallets RPC
  - bitcoin#10858 : "errors" to getblockchaininfo + unify "errors" field in get*info RPCs
  - bitcoin#11492 : Fix leak in CDB constructor
  - bitcoin#11476 : Avoid opening copied wallet databases simultaneously
  - bitcoin#11590 : always show help-line of wallet encryption calls
  - bitcoin#11289 : Add wallet backup text to import* and add* RPCs
