Library: Replace auto with real types (#4207) 
Following up on fc6c203b0e76, replace auto with the correct types to
clairfy the code. Note the use of const on the first type in the pair,
which allows us to use a reference.

library: Add new warning: ignoredReturnErrorCode (#2877) 
* library: Add optional "type" attribute to "use-retval"

Added an optional "type" attribute to "use-retval" nodes in the
configuration. When the return type of a function configured with
`<use-retval type="error-code"\>` node does not used, the new style
error "ignoredReturnErrorCode" will be generated.

* Fix and improve patch after the initial review

* Fixed severity level and [[nodiscard]] attribute

* Fix incorrect condition

* Remove redundant condition

Fix #9478: Valueflow: printf does not change value (#2388) 
Format-string arguments are now marked to have `in` direction, except
for `scan`-functions (like `scanf`) where these arguments are explicitly
marked to have `out` direction.

Check for JSON error when parsing addon .json files + fixes (#2374) 
* cppcheck.cpp: Check for JSON error when parsing addon .json files

This fixes that errors in JSON files given via `--addon=*.json` are
silently ignored and maybe only a part of the JSON file is used.
Now the error message which picojson can return is checked and a
corresponding error message is returned again by getAddonInfo().

* naming.json: Fix missing comma

* CLI: Fix naming violations detected by addon naming.py via naming.json

* Addon naming: Add argument for validating names of constants

* LIB: Rename functions/variables so they are valid, loosen naming rules

* GUI: Fix naming violations
