Sweetcomb global cleanup

-Merge IETF and Openconfig to use SCVPP 2
-Move L2 bridge from sc_vpp_interface to sc_vpp_v3po
-Implement tav2 dump
-Make openconfig-interfaces functions static
-Try one more dispatch after failure in VAPI_CALL
-Add error return code for scvpp
-Remove unused length maccros
-Return appropriate error code for interface dump when interface not found
-Improve scvpp test suite
-Change get_interface_id prototype
-Use interface_dump_iface in openconfig_interface.
-No more vapi types in openconfig_interfaces.c
-Move openconfig_local_routing VAPI operations to sc_vpp_ip
-Implement a multiple dump with a stack data structure
-Comment out state_cb code from openconfig_local_routing to use new
functions later.
-Rename YANG model to their fully qualified name : <module>@<revision>
-Remove headers almost empty and put registration declaration in
sc_model.h
-Shorten vapi context global variable name
-Reorganize scvpp unit test suite
-Add instructions to Makefile to install/uninstall YANG models in sysrepo.
-Add this new instructions to README.md.
-Reimplement interface_dump_all
-Use a common message at INFO Log Level to know when sysrepo callbacks
are triggered
-Remove old structure to perform dump of all interfaces
-Reimplement get_interface_name and add scvpp test for it
-Clean sys_util
-Use UNUSED maccro everywhere to have lighter prototypes
-Have ietf-interfaces:interfaces-state work with new dump function
-Add setup and teardown for NAT tests
-Remove unused tapv2 dump
-Remove useless sysrepo module callback
-Remove xpath_find_first_key usage in openconfig-interfaces
-Remove xpath_find_first_key in oc_local_routing and in the rest of
sweetcomb
-Reorganize scvpp include dir and fix scvpp_test new warnings
-Fix scvpp tests for ip routes
-Factorize scvpp nat and test return code of its function
-Correct test_dump_if_all if there is an existing hardware interface
-Implement a per-prefix dump in scvpp
-free changes iterator in ietf-interfaces
-Add new XPATH in oc local-routing
-Introduce helper methods for sysrepo config callbacks
-Factorize config callback
-Refactor the openconfig-local-routing config callback
-Use common foreach_change to iterate over changes in all models
-Create a sample directory gathering example of configurations supposed
to work with sweetcomb
-Fix state callback of oc-local-routing
-Add new sample for get operation on next-hop
-foreach_elt maccro condition forgets to read one element
