Jiyong Park 705abe2d30 OR_RETURN supports status_t 
This change provide a specialization of android::base::OkOrFail for
status_t. As a result, a statement whose type is status_t can be used
with OR_RETURN.

The specialization also provides conversion operators to Result<T,
StatusT> where StatusT is a wrapper type for status_t. This allows
OR_RETURN macro to be used in newer functions that returns Result<T,
StatusT>.

Example usage:

\#include <utils/ErrorsMacros.h>

status_t legacy_inner();

status_t legacy_outer() {
  OR_RETURN(legacy_inner());
  return OK;
}

Result<T, StatusT> new_outer() {
  OR_RETURN(legacy_inner()); // the same macro
  return T{...};
}
