patch 7.4.1844

Problem:    Using old function name in comment.  More functions should start
            with test_.
Solution:   Rename function in comment. (Higashi Higashi) Rename
            disable_char_avail_for_testing() to test_disable_char_avail().
            And alloc_fail() to test_alloc_fail().
