New `grouping-treeref` option added to clixon-autocli.yang
Default is disabled, set to true to generate smaller memory footprint of clixon_cl
Add prefix "mtpoint:" to cli api-paths to identify change of yang schemas
* Added flag names: `CLIXON_DBG_*`
* Added maskable flags that can be combined when debugging:
* `DEFAULT` = 1: Basic debug message, espcially initialization
* `MSG` = 2: Input and output packets, read datastore
* `DETAIL` = 4: Details: message dump in hex, xpath parse trees, etc
* `EXTRA` = 8: Extra detailed logs
* Test: some errors in yang-lib where content-id was in wrong place
* This enables full string lexical parsing of some rules previously not fully compliant, including:
* refine
* user-augment
* if-feature
* Also solves previous tokenization issues
Added configure option --with-mib-generated-yang-dir=DIR with
default value /usr/share/mibyang where generated YANGs from MIBs
should be placed so that SNMP tests know where to find the YANGs.
* Previous implementation did not handle nested if-feature expressions
* As part of fixing: [YANG if-feature does not support nested boolean expression](https://github.com/clicon/clixon/issues/341)
* Added new yacc/lex parser for if-feature-expr string
* Instead of removing YANG which is disabled by `if-feature`, replace it with an yang `anydata` node.
* This means XML specified by such YANG is ignored, and it is not an error to access it
* Note the similarity with `CLICON_YANG_UNKNOWN_ANYDATA`
* Removed obsolete options:
* `CLICON_YANG_LIST_CHECK`
* `CLICON_RESTCONF_PATH` (moved to restconf/fcgi-path)
* Fixed: Configure option `CLICON_RESTCONF_PRETTY` was marked as obsolete but was still used.
* `CLICON_RESTCONF_PRETTY` is now obsolete for sure
* Instead restconf/pretty is used with API function restconf_pretty_get()
* These were included for testing
* If you want to run the Clixon test suite you need to point `YANGMODELS`, see test/README.md
* The following configure options have been removed:
* `configure --with-opt-yang-installdir=DIR`
* `configure --enable-optyangs`
* You may need to specify standard YANGs using configure option `--with-yang-standard-dir=DIR`
* Updated yang ietf models with fetures for tet
* Added option `CLICON_YANG_AUGMENT_ACCEPT_BROKEN` to accept broken yangmodels.
* This is a debug option for CI testcases where standard YANG models are broken
Fixed cornercase of restconf error return when no body
Fixed cornercase when exactly / given as xpath
Better error message when YANG not found: added which YANG file imports it
