nfsd: Handle kuids and kgids in the nfs4acl to posix_acl conversion
In struct nfs4_ace remove the member who and replace it with an
anonymous union holding who_uid and who_gid. Allowing typesafe
storage uids and gids.
Add a helper pace_gt for sorting posix_acl_entries.
In struct posix_user_ace_state to replace uid with a union
of kuid_t uid and kgid_t gid.
Remove all initializations of the deprecated posic_acl_entry
e_id field. Which is not present when user namespaces are enabled.
Split find_uid into two functions find_uid and find_gid that work
in a typesafe manner.
In nfs4xdr update nfsd4_encode_fattr to deal with the changes
in struct nfs4_ace.
Rewrite nfsd4_encode_name to take a kuid_t and a kgid_t instead
of a generic id and flag if it is a group or a uid. Replace
the group flag with a test for a valid gid.
Modify nfsd4_encode_user to take a kuid_t and call the modifed
nfsd4_encode_name.
Modify nfsd4_encode_group to take a kgid_t and call the modified
nfsd4_encode_name.
Modify nfsd4_encode_aclname to take an ace instead of taking the
fields of an ace broken out. This allows it to detect if the ace is
for a user or a group and to pass the appropriate value while still
being typesafe.
