commit 8d9bf479441d9d7a44a86b69026a7e9d431d3ade

Author: Justin Mitchell <jumitche@redhat.com>

Date:   Tue Nov 7 09:28:25 2017 -0500

    nfs-utils: Restore ABI compat with pre-merge libnfsidmap

    Prior to merge libnfsidmap leaked many private symbols that were

    not defined in its API, creating an accidental ABI.

    This patch renames and unhides symbols in order to match that ABI

    until a cleaned up API can be established and released.

    Signed-off-by: Steve Dickson <steved@redhat.com>
