libnfsidmap-0.21 is available

[Kevin Coffman]

A new version of libnfsidmap is now available from
http://www.citi.umich.edu/projects/nfsv4/linux/libnfsidmap/libnfsidmap-0.21.tar.gz

Changes since libnfsidmap-0.20:

 - The main library has been changed to load "plugin" libraries to
perform the mappings.  This decouples the main library from any ldap
(and sasl, etc.) dependencies.

 - Several translation methods (plugins) may now be specified in the
idmapd.conf file.  While a plugin returns -ENOENT, the next is called
until a mapping is found, or there are no more plugins to try.  See
the notes in the updated sample idmapd.conf configuration file.

 - A "static" mapping plugin from David Härdeman <david at hardeman.nu>
has been added.

 - A "gums" mapping plugin from Olga Kornievskaia
<aglo at citi.umich.edu> has been added.  Olga also did most of the work
to convert the code to use this new plugin architecture.

 - The interface is changed to add two new functions,
nfs4_gss_princ_to_ids_ex(), and nfs4_gss_princ_to_grouplist_ex() which
allow extra information to be passed to these mapping functions.
