This include plugin module init and exit functions
New type: clixon_plugin_t exposed via public API while struct clixon_plugin is private
- Makefile changes for static linkage using "LINKAGE=static"
- Moved nacm external init to later stage in backend_main
* This means that files and datastores supporting modstate also looks for deleted or updated yang modules.
* A stricter binding which gives error if loading outdated YANG file does not exist.
* Stricter yang checks: you cannot do get-config on datastores that have obsolete YANG
* Added xerr output parameter to `xmldb_get0()`
- Stricter CLICON_BACKEND_RESTCONF_PROCESS :
- if set, restconf daemon queries backend for its config
- if not set, restconf daemon reads its config from main config file
- Restconf auth=none changes
- Load clixon-restconf and resolve features earlier so that config features work
- Removed auth=none code from example (this was non-std half-baked basic auth)
- Changed tests that used auth-type=none to enable feature clixon-restconf:allow-auth-none
- Moved cert creation from sub-shell to servercert function
- Fixed typos for dockerfile rename of restconf evhtp to native
* Hello message semantics has been made stricter according to RFC 6241 Sec 8.1, for example:
* A client MUST send a <hello> element.
* Each peer MUST send at least the base NETCONF capability, "urn:ietf:params:netconf:base:1.1" (or 1.0 for RFC 4741)
* The netconf client will terminate (close the socket) if the client does not comply
* You can set `CLICON_NETCONF_HELLO_OPTIONAL` to true to use the old behavior of essentially ignoring hellos.
* New clixon-config@2020-03-08.yang revision
* Added: `CLICON_NETCONF_HELLO_OPTIONAL`
* The base capability has been changed to "urn:ietf:params:netconf:base:1.1" following RFC6241.
* Replaces the hardcoded "config" keyword.
* Implemented by a compile-time option called `DATASTORE_TOP_SYMBOL` option in clixon_custom.h
* Tests: added endtest to all tests. Removed all premature exits if BE=0
* Introduced a delay before making process start/stop/restart processes for race conditions when configuring eg restconf
* For restconf `CLICON_BACKEND_RESTCONF_PROCESS`, restart restconf if restconf is edited.
* evhtp restconf closes session on -1 fatal error (no hang)
* restconf auth-type=none call ca_auth callback
* main example for auth_type=none uses basic auth to get user but without passwd check
* Fixed: [Augment that reference a submodule as target node fails #178](https://github.com/clicon/clixon/issues/178)
* Fixed a memory error that was reported in slack by Pawel Maslanka
* The crash printout was: `realloc(): invalid next size Aborted`
