settings: Avoid using a pointer and global data for algorithms.

Until now the difference between the current and global settings for
the algorithms in uses has been maintained as two values plus a pointer
to the setting actually in use.  Using global data like that makes it
harder to save and restore settings, so this commit adopt an alternate
method that avoids using global data or pointers.
