Subject: [PATCH] Added an exported function to enable/disable ble v3 from the
 dart UI including updating the UI. This is expected to be used in test and
 does not affect interfaces that are unaware of it (IOW, it breaks nothing and
 NS will still use v2). Now we can just switch back and forth between v2 and
 v3 without recompilation, but, it needs to be done carefully, once it's
 toggled toggling back should only be done when not advertising, discovering,
 or connected/ing. At some point, I will work out the logic for disabling it,
 it's gonna take a little dart coding.
