Originally, the high_quality_required boolean argument controlled two things: whether to extend any random data we successfully read with pseudo-random data, and whether to return -ENODATA if we couldn't read any data at all. The boolean got replaced by RANDOM_EXTEND_WITH_PSEUDO, but this name doesn't really cover the second part nicely. Moreover hiding both changes of behaviour under a single flag is confusing. Hence, let's split this part off under a new flag, and use it from random_bytes().
