[ticket/9612] Introduce new function gen_rand_string_friendly().
Introduce new function gen_rand_string_friendly() for user friendly random
strings like passwords and captcha codes. Strings generated by
gen_rand_string_friendly() will not contain the characters 0 and O.
By adding a new function we can increase the entropy of strings
generated by gen_rand_string() by putting 0 and O back in.
