could the PermissionRequestHandler be a member of AwWebContentsDelegate and not
AwContents?

[michaelbai, 2014/04/22 20:53:51]

Considering about the geolocation implementation, not all all requests are
coming from the delegate class, and PermissionRequestHandler should gotten from
AwContents and have same lifecycle with AwContents
