Subject: [PATCH] Remove options::getAll() (#7111)

options::getAll() returns a list of all options and their current values as strings. The same functionality can be obtained by using options::getNames() and options::get(). This PR does exactly this replacement, getting rid of a large chunk of generated code. Calling getInfo("all-options") may suffer a minor performance hit, but not noticeable in practice.
