idmapper fix
This patch makes the following modifications:

utf82uid/gid: Moved code that drops the @domain in the user name to name2uid/gid

name2uid/gid: Modified code such that if "username" fails to resolve an id, attempt "username@domain"
              Same logic modifed to USE_NFSIDMAP and !USE_NFSIDMAP code paths

Added new export config "Strip_NETBIOS_Name" that takes a list of clients.  Clients present in this list will
              have their NETBIOS\ domain name removed from the username "NETBIOS\username@domain"

uid/gid2utf8: Modified to pass pclient and pworker down to uid/gid2str.  These are needed to
              determine if the given client has the "Strip_NETBIOS_Name" option set

New function drop_slash_domain added:
              Removes the character string NETBIOS\ from a given user name "NETBIOS\username@domain"

New function strip_netbios_name: Helper function for uid2str and gid2str to determine if the client needs to have
                    the netbios name stripped from the uid/gid name for this export

uid/gid2str: Added logic to strip NETBIOS\ domain name from "NETBIOS\username@domain" if
             Strip_NETBIOS_Name option is present for this client

This will give more time to Ganesha at startup,
before it has to server reclaims.

Attempt to fix a ctdb issue
