Fix printf problems with high ascii characters after r413586 (1.8).

In r413586 (1.8) various casts were added to silence gcc 4.10 warnings.
Those fixes included things like:

    -out += sprintf(out, "%%%02X", (unsigned char) *ptr);
    +out += sprintf(out, "%%%02X", (unsigned) *ptr);

That works for low ascii characters, but for the high range that yields
e.g. FFFFFFC3 when C3 is expected.

This changeset:
- fixes those casts to use the 'hh' unsigned char modifier instead
- consistently uses %02x instead of %2.2x (or other non-standard usage)
- adds a few 'h' modifiers in various places
- fixes a 'replcaes' typo
- dev/urandon typo (in 13+ patch)
