Refactored common code between CallerInfo and CallerInfoAsyncQuery that deal with voicemail number comparison. In CallerInfo.java added a new field mIsVoiceMail to indicate this is a voicemail call. Added a new method to convert the CallerInfo into a VM instance. Added a new method to generate a debug string from an instance. PhoneNumberUtils has a new method "isVoiceMailNumber" to check if a number is a VM one. I left the method as hidden. Previously any security exception failure was cached in a static variable. I removed that and privilege the optmistic scenario. I am not sure if the security exception is only for the 'regular' telephony layer and if it applies if a 3rd party VM app is installed (e.g googlevoice), hence i removed the cashing to make sure we can pick up new voicemail providers when installed/enabled/disabled.
