Telephony: Introduce config item for Hot Swap support

When a Uicc Card is inserted or removed, Android pops up a prompt
to the user to reboot the device. This prompt is unnecessary if the
modem supports Hot Swapping of cards.

Introduce a new config item to indicate if the modem supports
hotswapping. Frameworks can then check this before propmting the
user.

Framework: Fix blacklist support

Copy & Paste isn't a good friend for programmers ;)

Fix ringer mode being unneededly changed by setting ringer mode volume to 0.

When having set the ringer mode to silent on a device with vibrator and
calling setStreamVolume() for the ringer stream again (e.g. in one of
the volume control dialogs in the settings app), the ringer mode is set
to vibrate, although there's no reason to do so.

Fix that by remembering the last non-normal (that is, either silent or
vibrate) ringer mode and using that when setting the stream volume to 0.
