/* DHCP Option names, formats and codes, from RFC1533.

   Format codes:

   I - IP address
   l - 32-bit signed integer
   L - 32-bit unsigned integer
   s - 16-bit signed integer
   S - 16-bit unsigned integer
   b - 8-bit signed integer
   B - 8-bit unsigned integer
   t - ASCII text
   f - flag (true or false)
   A - array of whatever precedes (e.g., IA means array of IP addresses)
   a - array of the preceding character (e.g., IIa means two or more IP
       addresses)
   U - name of an option space (universe)
   F - implicit flag - the presence of the option indicates that the
       flag is true.
   o - the preceding value is optional.
   E - encapsulation, string or colon-seperated hex list (the latter
       two for parsing).   E is followed by a text string containing
       the name of the option space to encapsulate, followed by a '.'.
       If the E is immediately followed by '.', the applicable vendor
       option space is used if one is defined.
   e - If an encapsulation directive is not the first thing in the string,
       the option scanner requires an efficient way to find the encapsulation.
       This is done by placing a 'e' at the beginning of the option.   The
       'e' has no other purpose, and is not required if 'E' is the first
       thing in the option.
   X - either an ASCII string or binary data.   On output, the string is
       scanned to see if it's printable ASCII and, if so, output as a
       quoted string.   If not, it's output as colon-seperated hex.   On
       input, the option can be specified either as a quoted string or as
       a colon-seperated hex list.
   N - enumeration.   N is followed by a text string containing
       the name of the set of enumeration values to parse or emit,
       followed by a '.'.   The width of the data is specified in the
       named enumeration.   Named enumerations are tracked in parse.c.
   d - Domain name (i.e., FOO or FOO.BAR).
