Add \o{} escape
This commit adds the new construct \o{} to express a character constant
by its octal ordinal value, along with ancillary tests and
documentation.
A function to handle this is added to util.c, and it is called from the
3 parsing places it could occur. The function is a candidate for
in-lining, though I doubt that it will ever be used frequently.
