misra: Don't consider variadic arguments as the violation of rule 2.7 (#3315)
The MISRA 2012 standard does not say anything about variadic functions
in the definition of rule 2.7. Therefore, these cases should be
considered as false positives.

misra: Fix crash on rule 8.2 (#3310)
The example code that reproduces this crash:

```
int misra_8_2_o(
    const uint32_t a1,
    const uint8_t *const a2
)
{ return *a2 + a1; }
int misra_8_2_p(
    const uint32_t a1,
    const uint8_t *const a2
);
```

The unit test was not added because it looks like a typo and regressions
are unlikely.

misra: Fix 8.2 false positives (#3309)
* misra: Fix 8.2 false positives

Fix false positives in rule 8.2 that occurred in cases when we have a
function definition and declaration in the same file.

For example, the following code generated false positives before this
commit:

```
void f(uint8_t * const x);
void f(uint8_t * const x)
{ (void)x; }
```

We need to distinguish the declaration and the definition, so the dump
file generation routine was extended to keep token where the definition
of the function. The analysis in the addon also been improved.

misra: Fix 8.2 false positives (#3306)
Type declaration on the next line is not allowed in rule 8.2. But we
need to make sure that the files of the checked files are the same.

misra: Fixed crash with struct fields with unknown types on 9.x rules (#3305)
This fixes the crash on with struct fields containing unknown types
reported on the forum:
https://sourceforge.net/p/cppcheck/discussion/general/thread/d64551cc55/#5f0f

The suggested patch doesn't handle the cases when there are struct
fields with arrays containing unknown types. So the addon will not
generate warnings in these cases. The problem is that Cppcheck doesn't
generate valueType-pointer information for unknown types in the dump
file. When adding this in symboldatabase.cpp, MISRA addon will generate
a lot of false positives because we depend on the null value of
valueType.

So I suppose it better to left this as is, to don't break the addon for
such rare cases.

misra: Add support for expected suppressions in header files in `-verify` mode (#3252)
This commit allows to specify expected suppressions in the included
header files. This is necessary to verify MISRA checkers, which make
requirements for header files. For example, Rule 8.2 requires adding
prototypes for each function to the header files.

cppcheckdata: Use instance attributes in Cppcheckdata (#3029)
This commit makes CppcheckData class to use instance attributes instead
of class attributes.

Since class attributes are mutable (list), when you append to them, they
don't promote to instance variable which means when you call parsedump()
multiple times data just gets appended to them.
