Add a new Registry distribution method for CellServDB info.

The CellServDB registry schema is as follows:

 HKLM\SOFTWARE\OpenAFS\Client\CellServDB\[cellname]\
   "LinkedCell"    REG_SZ "[cellname]"
   "Description"   REG_SZ "[comment]"
   "ForceDNS"      DWORD  {0,1}

 HKLM\SOFTWARE\OpenAFS\Client\CellServDB\[cellname]\[servername]\
   "HostName"      REG_SZ "[hostname]"
   "IPv4Address"   REG_SZ "[address]"
   "IPv6Address"   REG_SZ "[address]"   <future>
   "Comment"       REG_SZ "[comment]"
   "Rank"          DWORD  "0..65535"
   "Clone"         DWORD  "{0,1}"       <future - server only>
   "vlserver"      DWORD  "7003"        <future>
   "ptserver"      DWORD  ...           <future>

 ForceDNS is implied non-zero if there are no [servername]
 keys under the [cellname] key.  Otherwise, ForceDNS is zero.
 If [servername] keys are specified and none of them evaluate
 to a valid server configuration, the return code is success.
 This prevents failover to the CellServDB file or DNS.

Registry distributed info takes precedence over the CellServDB file.

Registry support has been added to both the Windows specific cm_config
interface and the auth/cellconfig interface utilized by aklog, the 
services, and the vast majority of support commands.

Enhance the DNS lookup for Cell vlserver info to support ranking info
which is used with _vlserver._udp SRV record lookups when AFSDB records
are not present.  Priorities become ranks.
