OptsVisitor, StringInputVisitor and the keyval visitor have three different ideas of how a human could write the value of a boolean option. Pay homage to the backwards-compatibility gods and make the new common helper accept all four sets (on/off, true/false, y/n and yes/no), but remove case-insensitivity.
Since OptsVisitor is supposed to match qemu-options, adjust it as well. Signed-off-by: Paolo Bonzini <pbonz...@redhat.com> Reviewed-by: Daniel P.
