Make the UTF-8 decoding stricter and more verbose when
malformation happens. This involved adding an argument to utf8_to_uv_chk(), which involved changing its prototype, and prefer STRLEN over I32 for the UTF-8 length, which as a domino effect necessitated changing the prototypes of scan_bin(), scan_oct(), scan_hex(), and reg_uni(). The stricter UTF-8 decoding checking uses Markus Kuhn's UTF-8 Decode Stress Tester from http://www.cl.cam.ac.uk/~mgk25/ucs/examples/UTF-8-test.txt p4raw-id: //depot/perl@7416
