Port to libyang 3
Refactor the code to switch to libyang 3: - the cdefs.h file is updated to match the new definitions - the flags used in lyd_new_* are regrouped in a newvaloptions bitmap - the log callback management is reworked - the system-ordered lists / leaf-lists are now ordered by key (hence the unit test change) Fixes: #105 Link: https://github.com/CESNET/libyang/blob/master/doc/transition_2_3.dox Signed-off-by: Stefan Gula <steweg@gmail.com> Signed-off-by: Samuel Gauthier <samuel.gauthier@6wind.com>
