Something called "ChooserPermissionManager" can't be this hard-wired to
Bluetooth. Assuming this will eventually support USB too, and that it can't fold
into the existing PermissionManager, can we do something similar to
https://code.google.com/p/chromium/codesearch/#chromium/src/content/public/br...
with a ChooserPermissionType enum (or even re-use PermissionType)?

Done.
