Pull request description:

  This is a move-only commit. No code is changing and the moves can be easily verified with:

  ```sh
  git log -p -n1 --color-moved=dimmed_zebra
  ```

  This commit moves functions and variables that wallet code depends on out of libbitcoin_server.a, so the bitcoin-wallet tool can be built without libbitcoin_server.a in #15639, and attempting to access server state from wallet code will result in link errors instead of silently broken code.

  List of moves:

  - `CheckTransaction` moves from `consensus/tx_verify.cpp` to `consensus/tx_check.cpp`
  - `urlDecode` moves from `httpserver.cpp` to `util/url.cpp`
  - `TransactionErrorString` moves from `node/transaction.cpp` to `util/error.cpp`
  - `StringForFeeReason` and `FeeModeFromString` move from `policy/fees.cpp` to `util/fees.cpp`
  - `incrementalRelayFee` `dustRelayFee` and `nBytesPerSigOp` move from `policy/policy.cpp` to `policy/settings.cpp`
  - `SignalsOptInRBF` moves from `policy/rbf.cpp` to `util/rbf.cpp`
  - `fIsBareMultisigStd` moves from `validation.cpp` to `policy/settings.cpp`
  - `ConstructTransaction` `TxInErrorToJSON` and `SignTransaction` move from `rpc/rawtransaction.cpp` to `rpc/rawtransaction_util.cpp`
  - `RPCTypeCheck` `RPCTypeCheckArgument` `RPCTypeCheckObj` `AmountFromValue` `ParseHashV``ParseHashO` `ParseHexV` `ParseHexO` `HelpExampleCli` and `HelpExampleRpc` move from `rpc/server.cpp` to `rpc/util.cpp`
  - `AmountHighWarn` and `AmountErrMsg` move from `ui_interface.cpp` to `util/error.cpp`
  - `FormatStateMessage` and `strMessageMagic` move from `validation.cpp` to `util/validation.cpp`
  - `VerifyWallets` `LoadWallets` `StartWallets` `FlushWallets` `StopWallets` and `UnloadWallets` move from `wallet/init.cpp` to `wallet/node.cpp`

  jnewbery:
    utACK 4d074e84a2 (checked by doing the rebase myself and verifying no difference between my branch and 4d074e84a2)

# src/node/
The [`src/node/`](./) directory contains code that needs to access node state
(state in `CChain`, `CBlockIndex`, `CCoinsView`, `CTxMemPool`, and similar
classes).
Code in [`src/node/`](./) is meant to be segregated from code in
[`src/wallet/`](../wallet/) and [`src/qt/`](../qt/), to ensure wallet and GUI
code changes don't interfere with node operation, to allow wallet and GUI code
to run in separate processes, and to perhaps eventually allow wallet and GUI
code to be maintained in separate source repositories.
As a rule of thumb, code in one of the [`src/node/`](./),
[`src/wallet/`](../wallet/), or [`src/qt/`](../qt/) directories should avoid
calling code in the other directories directly, and only invoke it indirectly
through the more limited [`src/interfaces/`](../interfaces/) classes.
The [`src/node/`](./) directory is a new directory introduced in
[#14978](https://github.com/bitcoin/bitcoin/pull/14978) and at the moment is
sparsely populated. Eventually more substantial files like
[`src/validation.cpp`](../validation.cpp) and
[`src/txmempool.cpp`](../txmempool.cpp) might be moved there.
