To assist in making permissions attribution more robust at the ContextHub service level, tweak the V1.2 interface with the following changes: - Return the full list of supported permissions that all hubs support for attribution. This assists in limiting the number of permissions strings sent between the HAL and service to only those the HAL actually attempts to use. - Add new parameter to handleClientMsg_1_2 that allows nanoapps to denote the list of attributable permissions relating to the contents of the message being sent. This is strictly a subset of the permissions the nanoapp holds and allows a message to be sent without attributing the full nanoapp permission set to the host client when the message may not have been generated from data covered by the permissions. Bug: 166846988 Test: compile Change-Id: I2dc8e1ab4fce2a9ebcc393d07fdffe23dfceb4c2
