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

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

character, so do not warn about this.

rikardfalkeborn 613dc19b68 #4241: Check for address of single character passed as string (#1381)
* #4241: Check for address of single character passed as string

Add a check that address of a single character is not passed as argument
to argument marked as strings (using strz). The check does not warn if
the address of a character with known value '\0'.

Since ValueFlow currently does not handle global constants (see #7597),
do not warn if the variable is global to avoid FPs when the address of
a global variable assigned to '\0' is passed to a function expecting a
string.

Remove comment in docs saying strz is unused.

* Change asdf to Hello world

* Add test of address to first element in string

* Add error reporting function to getErrorMessages

* Fix strings in test

rikardfalkeborn 710d7ce015 Add checks of log2 and log1p range (#1324)
* Add tests for log10{,f,l} valid arguments

* Add log2{,f,l} to checkfunctions

* Add log1p{,f,l} to checkfunctions

* checkfunctions: Simplify check for log function limit out of range

The conditions for negative and non-negative int and float were
identical so the call to isNegative can be removed and the if-statements
be simplified.
