Delete frameworks/base/voip use voip-common from frameworks/opt/net/voip

Add voip-common to various files so that its available when booting
and building. Basically everyplace telephony and mms-common where needed
voip-common was added.

In core/pathmap.mk voip is removed as it is no longer in frameworks/base.
