0000fb3fd9doc: Remove outdated and stale todo comment (MarcoFalke)fa2b529f92refactor: Remove redundant call to IsArgSet (MarcoFalke)fa29842c1frefactor: Remove IsArgSet guard when fallback value is provided (MarcoFalke) Pull request description: `IsArgSet` is problematic: * It returns whether an arg has been set, even if it has been negated. `IsArgSet` is sometimes used to check for a truthy value, which is wrong, but usually harmless. Cleanup of those cases may or may not be done in a follow-up. * In most other cases, calling it is redundant, because the immediately following `Get*Arg` calls can already return an `std::optional` nullopt value to indicate an unset arg. So relieve both issues by removing all `IsArgSet` that are redundant. ACKs for top commit: pablomartin4btc: re-ACK0000fb3fd9ryanofsky: Code review ACK0000fb3fd9.

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/ and src/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/, or src/qt/ directories should avoid
calling code in the other directories directly, and only invoke it indirectly
through the more limited src/interfaces/ classes.
This directory is at the moment
sparsely populated. Eventually more substantial files like
src/validation.cpp and
src/txmempool.cpp might be moved there.
