Added support for list x y;
Uses a mechanism to parse as unknown XML body and post-parsing replace with list keys
Fixed example and test to work with new TEXT syntax
New API is as follows:
* `clixon_xml2file()` - Print internal tree as XML to file
* `clixon_xml2cbuf()` - Print internal tree as XML to buffer
* `clixon_json2file()` - Print internal tree as JSON to file
* `clixon_json2cbuf()` - Print internal tree as JSON to buffer
* `clixon_cli2file()` - Print internal tree as CLI format to file
* `clixon_txt2file()` - Print internal tree as text format to file
* Added new text syntax parsing and loading from CLI
* Unified text output functions to `xml2txt` and moved to clixon_text_syntax.[ch]
* The following are removed: `cli_xml2txt` and `xml2txt_cb`
* Text output format changed:
* Namespace/modulename added to top-level
* See [Support performant load_config_file(...) for TEXT format](https://github.com/clicon/clixon/issues/324)
* Added `skiptop` parameter, if set only apply to children of a node, skip top node
* default is 0
* Functions are merged, ie removed and replaced with more generic functions
* `xml2json_cbuf()`: Added `skiptop` parameter: `xml2json_cbuf(..., int skiptop)`
* `xml2json()` and `xml2json_cb()` merged into `xml2json_file()` with `skiptop`
* Replace `xml2json(...)` with `xml2json_file(..., stdout, 0)`
* Replace `xml2json_cb(...)` with `xml2json_file(..., 0)`
* `clicon_xml2cbuf()`: Added `skiptop` parameter: `clicon_xml2cbuf(..., int skiptop)`
* `xml2cli()`: Added `skiptop` parameter: `xml2cli(..., int skiptop)`
* Note that edits to the candidate database or locks will be lost
* To force the CLI to exit if backend restarts, undef `PROTO_RESTART_RECONNECT`
* This is an effect of the fix of [Broken pipe error seen in client (cli) when backend restarts and CLICON_SOCK is recreated](https://github.com/clicon/clixon/issues/312), the CLI behavior on backend restart is changed.
* Added `eof` parameter to `clicon_rpc()` and `clicon_rpc1()` and error handling modified
* Load/save JSON config file did not work
* Added rfc7951 parameter to `clixon_json_parse_string()` and `clixon_json_parse_file()`
* If set, honor RFC 7951: JSON Encoding of Data Modeled with YANG, eg it requires module name prefixes
* If not set, parse as regular JSON
* Test: added test_db.sh for datastore format tests
* Fixed: [very slow execution of load_set_file #288](https://github.com/clicon/clixon/issues/288)
* New `clixon-lib@2021-11-11.yang` revision
* Modified option: RPC stats extended with YANG stats
* Modified `clixon-config@2021-11-11.yang` revision
* Added option:
* CLICON_PLUGIN_CALLBACK_CHECK
* Enable to make plugin context check before and after all callbacks.
* Added statistics for YANG: number of objects and memory used
* Use the treeref no-copy option of CLIgen to reduce memory
* Refactored cli-generation/autocli-start code
* Refactored cligen glue functions to use cligen_eval directly (remove clicon_eval,clixon_cligen_eval)
* Added ancestor config cache indicating wether the node or an ancestor is config false or true
* Improved yang cardinality lookup
* Added yang_init(), called from all apps using yang
- Fix event exit bug (set to new counter, dont increment)
- Changed default CI to be restconf=native instead of fcgi1~
- Tests:
- Change to same wait backend and restconf commands
- Change default restconf protocol from http to https
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
* 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
* Solution description using openssh and utility functions, no changes to core clixon
* Example: test/test_netconf_ssh_callhome.sh
* RESTCONF Call home not done
* Applies to cli/netconf/restconf/client-api code
* Previous behaviour:
* Close socket after each rpc, but now keeps the socket open until the client terminates
* Kept locks over socket life-cycle, but according to RFC 6241 7.5 a lock should be relaeased when session ends
* `count`, `name`, `contains`, `not`, as defined in [xpath 1.0](https://www.w3.org/TR/xpath-10)
* `deref`, `derived-from` and `derived-from-or-self` from RFC7950 Section 10.
* in particular in augment/when statements
* Improved error handling
* Verification of XPath functions is done at startup when yang modules are loaded, not when XPaths are evaluated.
* Separation of "not found" and "not implemented" XPath functions
* Both give a fatal error (backend does not start).
