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

This fixes the issue by making `ProgramMemory` keep track of values based on the conditions.

It also removes the `deadpointer` check since it duplicates the `invalidLifetime` check.

Paul Fultz II ee7fe3aaa1 Fix FP: Unitialized variable when using a pointer
This fixes the FP in cases like this:

```cpp
void f() {
    bool b;
    bool * x = &b;
    if (x != nullptr)
        x = 1;
}
```

It tracks the indirection of the uninit value in valueflow.
