David Hankins f7fdb21693 - Varying option space code and length bit widths (8/16/32) are now 
supported.  This is a milestone in acheiving RFC 3925 "VIVSO" and
  DHCPv6 support. [ISC-Bugs #15979]

/* 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
T - Lease Time, 32-bit unsigned integer implying a number of seconds from
some event. The special all-ones value means 'infinite'. May either
be printed as a decimal, eg, "3600", or as this name, eg, "infinite".
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).
