style

removed numerous ununsed extern variable declarations

969. [func] dig now supports the undocumented dig 8 feature of allowing arbitrary labels, not just dotted decimal quads, with the -x option. This can be used to conveniently look up RFC2317 names as in "dig -x 10.0.0.0-127". [RT #827, #1576, #1598]

947. [bug] dns_rdata_soa_t had a badly name element "mname" which was really the RNAME field from RFC1035. To avoid confusion and silent errors that would occur it ther "origin" and "mname" elements were given their correct names "mname" and "rname" respectively, the "mname" element is renamed to "contact".

Changes to support win32

Minor bug fixes to support win32

missing space in AAAA output [RT #1051]

miccing cancel_all in nslookup.

simplify dig/host/nslookup code by using the _format() functions in more places; fix spacing issues; make nslookup print debugging details for all lookup results, not just those with rcode==0; add comments

misc cleanup

More searchlist/domain handling fixes. Dig/host/nslookup no longer have the notion that there can be both a search list and a default domain at the same time. The resolv.conf "domain" directive is now used only if there is no "search" directive, and is treated exacly like a one-element searchlist. The "+domain" option of dig and the "set domain" command of nslookup are now merely ways of overriding the resolv.conf search list. Parents of the name given in the "domain" directive are still not searched; this is considered a feature and is consistent with lwres, but different from the BIND 8 resolver. The "+defname" option to "dig" is now deprecated and treated as a synonym for "+search"

consolidate duplicated code.

use isc_app_block instead of an ugly hack.

685. [bug] nslookup should always use the search list/domain options from resolv.conf, and it (and host) should use the search list items first. [RT #405, #630]

don't hardcode the magic constant 41

use dns_name_format() in more places

breaking out the SOA fields by calling dns_rdata_totext() and then tokenizing the text representation is sick and demented

682. [bug] nslookup diplayed SOA records incorrectly. [RT #665]
