atm: Replace custom isprint() with generic analogue
Custom isprint() definition may collide with one form ctype.h. In order to avoid this, replace it with a functional analogue which is isascii() && isprint() in this case. First appearance of the code is in the commit 636b38438001 ("Import 2.3.43").
