- Ensure that option length fits inside data length less option size.
(can lead to an invalid read/crash via malformed dhcp responses)

http://roy.marples.name/projects/dhcpcd/info/76a1609352263bd9
- dhcp_optlen now returns the length of the data we can sanely work
on given the option definition and data length. Call dhcp_optlen in
dhcp_envoption1 to take into ensure these bounds are not overstepped.
Fixes an issue reported by Nico Golde where extra undersized data was
present in the option. An example of this would be an array of uint16's
with a trailing byte.
(reporter says "exploitation is non-trivial, but i'd love to be
proven wrong.")
