Refactoring for better performance of large auto-cli specs
* 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)
