vl: allow full-blown QemuOpts syntax for -global
-global does not work for drivers that have a dot in their name, such as cfi.pflash01. This is just a parsing limitation, because such globals can be declared easily inside a -readconfig file. To allow this usage, support the full QemuOpts key/value syntax for -global too, for example "-global driver=cfi.pflash01,property=secure,value=on". The two formats do not conflict, because the key/value syntax does not have a period before the first equal sign. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

In particular, you can use this to set driver properties for devices which are

created automatically by the machine model. To create a device which is not

created automatically and set properties on it, use -@option{device}.

The two syntaxes are equivalent. The longer one works for drivers whose name

contains a dot.
