Handle original search domains in resolv.conf type implementations. - parse the original resolv.conf file - merge the search domains - ignore the domain keyword - append any other config lines (sortstlist, options) - fix read origin resolv.conf from bkp in resolvconf implementation - fix line length validation - fix number of search domains validation
