Fix handling of namespace scope with several bodystarts ( #3438 )
...
Follow up to 0093452bed
.
Give the proper end to getVariableList, since it might not be bodyEnd.
Before that, getVariableList would add the same variables in several
unrelated scopes, and all kind of false positive would follow.
For instance, with the case I added in the unit-tests, I had:
```
../code.cpp:15:18: warning: The struct 'is_A' defines member variable with name 'foo' also defined in its parent struct 'is_A_impl'. [duplInheritedMember]
static const int foo = 8;
^
../code.cpp:15:18: note: Parent variable 'is_A_impl::foo'
static const int foo = 8;

../code.cpp:15:18: note: Derived variable 'is_A::foo'
static const int foo = 8;

Remove usage of std::vector and getArguments from getTokenArgumentFunction ( #3435 )
...
getTokenArgumentFunction can be called many many times, and the vector
is not needed, but it can become quite costly.
This patch replaces getArguments with a function simply returning the
position of the token, if it is found in the arguments (thus saving the
cost of std::vector).

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.

Improve support for labels in simplifyAddBraces step ( #3278 )
...
Previously only a single regular label before a compound statement was
allowed in simplifyAddBracesPair() after if/switch/do/while/for.
This patch adds support for:
* case-labels;
* labels before a single statement;
* labels before try/catch blocks;
* multiple consecutive labels.
Additionally the code for skipping a case label was extracted into a
separate function from simplifyLabelsCaseDefault() and reused in
simplifyAddBracesPair().
