With the new ipa_server_mode SSSD is able to read user and group data from trusted AD domains directly and makes this data available via the NSS responder. With this mode enabled winbind is not needed anymore to lookup users and groups of trusted domains. This patch removed the calls to winbind from the extdom plugin and replaces them with standard POSIX calls like getpwnam() and calls from libsss_nss_idmap to lookup SIDs. Fixes https://fedorahosted.org/freeipa/ticket/3637 because now the extdom plugin does not need to handle idranges anymore, but everything is done inside SSSD.
