369d1314de Rename dhcp6_prefix to delegated_dhcp6_prefix incase a user makes a 
DHCPv6 option just called prefix.
Send delegated interfaces to listeners as well.

3bdae69ccf Remove strcpy as it's "dangerous". 
Can't use stpcpy for the same reason even though it's perfect for the job.

8f008ca7f5 Remove vis based encoding - instead expand the DHCP option encoding to a 
natural string based on content except as noted:
  *  domain (RFC3397)/dname (string) is strict domain name allowance
     (ie, [alnum] with _- (but not at the start or end))
  *  string is now printable ascii (1-127) until invalid
  *  ascii is all ascii (1-127) until invalid
  *  raw is all chars (1-255) until NUL
  *  binhex is a hex representation of the option including embedded NULs
  *  ssid is still escpaed octal because it's expected to be human readable
     AND can technically be all NUL
  *  everything else has strict option -> value encoding

This removes all shell escaped encoding - dhcpcd will assume that IF the
--script option is a shell, it will quote variables correctly.
The stock dhcpcd-run-hooks does.

dhcpcd -V now prints how the variables will be decoded.

Changed some options in dhcpcd-definitions.conf to more sensible defaults.

bc51f492ad Some strings don't need to be shell escaped - for example when sending to 
syslog(2), so just use vis(3).

4f2199843d Sanitise the following characters using svis(3) with VIS_CTYLE and VIS_OCTAL: 
| ^ & ; < > ( ) $ ` \ " ' <tab> <newline>
This allows a non buggy unvis(1) to decode it 100% and stays compatible with
how dhcpcd used to handle encoding on most platforms.
For systems that supply svis(3) there is a code reduction, for systems that
do not, a slight code increase.

This change mitigates systems affected by bash CVE-2014-6271 and CVE-2014-7169.
