Use encoder id as insecure DP encoder random seed
Originally all apps that use insecure DP encoder will generate
the same result in IRR encoder as IRR is purely rely on random generator,
hence all apps will return the same IRR result in encodeBoolean() for
insecure encoder.
Now we change insecure encoder to use encoder id as random generator seed,
so different app will have different deterministic insecure encoder result.
Also, this CL fixes some existing failed tests.

Add differential privacy library and algorithms
- Created a differential privacy framework interface
- Added 2 DP algorithms in DP framework:
- Rappor, a wrapper based on external/rappor project
- Longitudinal Reporting, DP enhancement based on Rappor
- Created Privacy Tests for testing all privacy libraries
- Added original Rappor test case in privacy test
- Created tests to verify Rappor and Longitudinal Reporting result in DP framework
