MINOR: ist: add ist_find_ctl() This new function looks for the first control character in a string (a char whose value is between 0x00 and 0x1F included) and returns it, or NULL if there is none. It is optimized for quickly evicting non-matching strings and scans ~0.43 bytes per cycle. It can be used as an accelerator when it's needed to look up several of these characters (e.g. CR/LF/NUL).
