This change also modifies the ndhc/ifchd wire protocol slightly. The new protocol doesn't overload the ':' character as a key:value separator and a statement separator. Instead ';' is now used as a statement separator. The new format allows for more robust error-checking and reporting, and it greatly simplifies the parser. Old versions of ndhc/ifchd will not work properly with ones compiled after this commit. The 'domain' and 'search' keywords in resolv.conf updates are now used more precisely. The first domain in an update is the 'domain', and the subsequent 5 domains are 'search' domains. There are also supporting cleanups that pass struct ifchd_client pointers to functions instead of passing index values. This commit is large, but it cannot really be broken up into smaller chunks since the changes are dependent on each other.
