We used the system proterties as a shared memory mechanism to propagate information to local settings caches when the content has changed and the cache should be cleared. The system properties are unfortunately updated asynchronously leading to cases where clients may read stale data. This change adds a simple int array data structure backed by shared memory which guarantees individual values are atomically read and updated without memory tear. Multi- index opearations are not synchronized between each other. The settings provider is using the new data structure to propagate the settings generation which drives when caches are purged. We have a single memory array keeping the generation for different settings tables per user. Since memory array is not a compact data structure and the user space exceeds the memory array size we use an in-memory map from keys to indices in the memory array where the generation id of a key is stored. A key is derived by the setting type in the 4 most significant bits and the user id in the 28 least significant bits. The mapping from a key to an index is cleared if the user is removed and the corresponding index in the memory arry is reset to make it available for other users. The size of the memory array is derived from the max user count that can be created at the same time. bug:18826179 Change-Id: I64009cc5105309ef9aa83aba90b82afc8ad8c659
