This contains most of the changes of 10563 "remove safe mode", but doesn't
remove the safe mode yet, but put an `ObserveSafeMode()` check in
individual calls with okSafeMode=false.
This cleans up the ugly "okSafeMode" flag from the dispatch tables,
which is not a concern for the RPC server.

This is necessary because core_write has to write amounts in
TxToUniv, and mistakingly uses FormatMoney for that
(which is only for debugging).
We don't move AmountFromValue at the same time, as
this is more challenging due to the RPCError depencency
there.
It has no business in `rpcserver.h`. Define it in the interface header
of the implementation unit `rpcblockchain` where it is defined.
Also modernize the signature to:
double GetDifficulty(const CBlockIndex* blockindex = nullptr);
(remove `extern`, replace `NULL` with `nullptr`)
The [JSON-RPC specification](http://www.jsonrpc.org/specification) allows passing parameters as an Array, for by-position
arguments, or an Object, for by-name arguments.
This implements by-name arguments, but preserves full backwards compatibility. API using by-name arguments are
easier to extend, and easier to use (no need to guess which argument goes where).
Named are mapped to positions by a per-call structure, provided through the RPC command table.
Missing arguments will be replaced by null, except if at the end, then the argument is left out completely.
Currently calls fail (though not crash) on intermediate nulls, but this should be improved on a per-call basis later.
waitfornewblock waits until a new block is received, or the timeout expires, then
returns the current block height/hash.
waitforblock waits for a specific blockhash, or until the timeout expires, then
returns the current block height/hash. If the target blockhash is the current
tip, it will return immediately.
waitforblockheight waits until the tip has reached a certain height or higher,
then returns the current height and hash.
waitforblockheight is used to avoid polling in the rpc tests.
Also introduce UniValueType
UniValueType is a wrapper for UniValue::VType which allows setting
a typeAny flag. This flag indicates the type does not matter.
(Used by RPCTypeCheckObj)
Split out methods to every module, apart from 'help' and 'stop' which
are implemented in rpcserver.cpp itself.
- This makes it easier to add or remove RPC commands - no longer everything that includes
rpcserver.h has to be rebuilt when there's a change there.
- Cleans up `rpc/server.h` by getting rid of the huge cluttered list of function definitions.
- Removes most of the bitcoin-specific code from rpcserver.cpp and .h.
Continues #7307 for the non-wallet.
Creates the generatetoaddress rpc which is virtually identical to the generate rpc except that it takes an argument for the address to mine to. It does not rely on wallet functionality.
The mining code shared by generate and generatetoaddress has been moved to another method to reduce duplication.
