Subject: [PATCH 3/8] nss-imap: add sss_nss_getsidbyuid() and
 sss_nss_getsidbygid()

Two new calls are added to allow the caller to specify if the given
POSIX ID is a UID or a GID and the expected result is a user or a group
respectively. This is needed because on POSIX a user and a group may
share numerically the same ID value but might have different SIDs
assigned.
