This commit updates `VerifyOrQuit()` and `SuccessOrQuit()` macros to
include the failed condition in the error message that is printed on
a failure (in addition to function name and line number where the
error happened). This commit also changes the second parameter
(`aMessage`) to in these macros to be optional.
This commit also updates unit tests to remove the second `aMessage`
string in cases where the failure can be inferred from the condition
itself.
This commit adds a new class `MeshCoP::SteeringData` which manages
the Steering Data and bloom filter generating and filtering. This
commit also adds a unit test `test-steering-data` for the newly
added `SteeringData` class.
