Get rid of calls to ctype.h functions.
They don't handle values outside the range -1 to 127, and their behavior
is locale-dependent. Use g_ascii_isXXX() and g_ascii_toXXX() instead of
isXXX() and toXXX().
If you're checking for printable ASCII, don't use isascii() and don't
use iscntrl(), use g_ascii_isprint(). If you're checking for graphical
ASCII, i.e. printable ASCII except for a space, use g_ascii_isgraph().
Use ws_xton() to convert a hex digit character to the corresponding
numeric value.
