qapi, qemu-options: make all parsing visitors parse boolean options the same

Browse source 
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.
