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{...};
}
