[nobu (Nobuyoshi Nakada)]

Some symbols exported in headers under internal are declared and used in some extension libraries.
These seem OK to be moved to public headers.

• ruby_scan_digits
  cgi/escape, date
• ruby_hexdigits
  cgi/escape, objspace
• ruby_digit36_to_number_table
  cgi/escape
• rb_int_positive_pow
  date
• rb_deprecate_constant
  etc
