All option write accesses are now put through the property interface, which means runtime option value verification and runtime updates are applied. This is done even for command line arguments and config files. This has many subtle and not-so-subtle consequences. The potential for unintended and intended subtle or not-subtle behavior changes is very large. Architecturally, this is us literally jumping through hoops. It really should work the other way around, with options being able to have callbacks for value verification and applying runtime updates. But this would require rewriting the entirety of command.c. This change is more practical, and if anything will at least allow incremental changes. Some options are too incompatible for this to work - these are excluded with an explicit blacklist. This change fixes many issues caused by the mismatch between properties and options. For example, this fixes #3281.
