* 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.py: Fix 12.3 FP for variables defined in headers ( #2773 )
...
When we include the header file with variables definitions, Cppcheck
will write `variables` entries with line numbers from the header to the
dump file.
If the line number in the header file and the source file are equal,
misra.py performs an additional check what leads to false positives.
Minimal example that demonstrates the problem:
`misra_fp.c`:
```c
void test_12_3_fp(void)
{
//Initialize the events queue
QEQueue_init(&me->deferred_event_queue, me->deferred_events_queue_buf, Q_DIM(me->deferred_events_queue_buf));
}
```
`misra_fp.h`:
```c
static const uint32_t timer_max_blocking_call_us;
```
