- Remove dead declarations in expr.h: SetError(), GetError(), ClearError(). - Remove the declaration of Build() out of expr.h. - Use std::unordered_map to implement RegisterFunction() and FindFunction(); kill FinishRegistration(). - Add a testcase for calling unknown functions. Test: mmma bootable/recovery; recovery_component_test passes. Change-Id: I9af6825ae677f92b22d716a4a5682f58522af03b
