* Merge branch 'dcornejo-master'
* Broke out pagination callback API from state data callbacks
* New pagination callback API uses new dispatcher from netgate, thanks @dcornejo
* Register callback with: `clixon_pagination_cb_register()`
* Use accessor functions `pagination_offset()`, `pagination_limit()`, etc
* Reverted state data callback API to pre-5.3 (see C/CLI API changes below)
* You need to change all statedata plugin callback for the new pagination feature
* If you dont use pagination you can ignore the values of the new parameters
* See [User manual pagination](https://clixon-docs.readthedocs.io/en/latest/misc.html#pagination)
* The updated callback signature is as follows:
```
int statedata(clicon_handle h,
cvec *nsc,
char *xpath,
pagination_mode_t pagmode, // NEW
uint32_t offset, // NEW
uint32_t limit, // NEW
uint32_t *remaining, // NEW
cxobj *xstate)
```
* The new callback contains parameters for paging
* Goal is to replace ca_statedata callback
* New plugin callback when lock/unlock occurs
* Add `ca_lockdb` tro plugin init to use it.
* Fixed: Typing 'q' in CLI more paging did not properly quit output
* Output continued but was not shown, for a very large file this could cause considerable delay
* Fixed: Lock was broken in first get get access
* if the first netconf operation to a backend was lock;get;unlock, the lock was broken in the first get access.
* That is, to configure with fcgi, you need to explicitly configure: `--with-restconf=fcgi`
* Updated main example to native restconf and several other fixes
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* A stricter binding which gives error if loading outdated YANG file does not exist.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()`
- 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
* Not backward compatible: All uses of the ca-auth callback in restconf plugins must be changed
* New version is: `int ca_auth(h, req, auth_type, authp, userp)`
* where `auth_type` is the requested authentication-type (none, client-cert or user-defined)
* `authp` is the returned authentication flag
* `userp` is the returned associated authenticated user
* and the return value is three-valued: -1: Error, 0: not handled, 1: OK
* For more info see [clixon-docs/restconf](https://clixon-docs.readthedocs.io/en/latest/restconf.html)
* 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
* Not backward compatible: All uses of the ca-auth callback in restconf plugins must be changed
* New version is: `int ca_auth(h, req, auth_type, authp, userp)`
* where `auth_type` is the requested authentication-type (none, client-cert or user-defined)
* `authp` is the returned authentication flag
* `userp` is the returned associated authenticated user
* and the return value is three-valued: -1: Error, 0: ignored, 1: OK
* For more info see [clixon-docs](https://clixon-docs.readthedocs.io/en/latest/restconf.html)
* New clixon-restconf@2020-12-30.yang revision
* This is an alternative to manage a clixon daemon via sudtemd, containerd or other
* One important special case is starting the clixon-restconf daemon internally
* This is how it works:
* Register a process via `clixon_process_register(h, name, namespace, argv, argc)`
* Use process-control RPC defined in clixon-lib.yang to start/stop/restart or query status on that process
* Example code in the main example
* Added: autocli-op extension (see new features)
* Added: rpc process-control for process/daemon management
* Added enable flag and removed presence in clixon-restconf
The `xmldb_put` is failing due to the `x_spec` field not being set on the xml tree (`xt`) due to no yang spec being passed to the `clixon_xml_parse_string` function.
* Added new revision of main example yang: `clixon-example@2020-12-01.yang`
* Fixed [YANG: key statement in rpc/notification list #148](https://github.com/clicon/clixon/issues/148)
* Do not check uniqueness among lists without keys
