options: allocate dynamic options with talloc

Allocate data structures for dynamic option values with talloc.
Hopefully there's no code left that tries to modify those dynamic
option values outside the option parser and relies on them being
malloc-allocated. Currently talloc functionality isn't used much and
the allocations are not hierarchical, so the main practical use for
now is just to allow very easy checking for memory leaks.
