fd5d71e Update developer notes after params.size() cleanup (Russell Yanofsky)

Pull request description:

This is a followup to #10783.

- The first commit doesn't change behavior at all, just simplifies code.
- The second commit just changes RPC methods to treat null arguments the same as missing arguments instead of throwing type errors.
- The third commit updates developer notes after the cleanup.
- The forth commit does some additional code cleanup in `getbalance`.

Followup changes that should happen in future PRs:

- [ ] Replace uses of `.isTrue()` with calls to `.get_bool()` so numbers, objects, and strings cause type errors instead of being interpreted as false. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133850525
- [ ] Add braces around if statements. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133851133
- [ ] Maybe improve UniValue type error exceptions and eliminate RPCTypeCheck and RPCTypeCheckArgument functions. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133829303

Build Bitcoin-ABC / Diffs / Diff Testing passed.

Harbormaster completed remote builds in B7321: Diff 11089.Sep 4 2019, 21:26

rpc/blockchain.cpp changes were made here: D954
rpc/mining.cpp changes were excluded because we did not backport much of Core's fee code.
Changes to rpc/misc.cpp that were excluded were to outdated logging code.
signrawtransaction() was removed after being deprecated: D3978

src/wallet/rpcwallet.cpp
3009 ↗	(On Diff #11089)	The next block of code is different from the original PR due to an out of order backport: D3420.

The changes to rpc/misc.cpp are missing.
It's not from an outdated code, but applies to the logging RPC backport that you did (stack starting from D3464). You need to rebase this diff on top of it.
The setaccount change is missing from rpcwallet.cpp (alias for setlabel).

src/wallet/rpcwallet.cpp
