qemu_opt_del() already assumes that all QemuOpt instances contain
malloc'd name and value; but it had to cast away const because
opts_start_struct() was doing its own thing and using static storage
instead. By using the correct type and malloced strings everywhere, the
usage of this struct becomes clearer.

While touching this, is it worth trimming the extra spacing before '*'?
It's not like you are preserving alignment or anything. But as that's
cosmetic, and as the code itself is correct, I'm fine if you add this
when you expand your commit message:
