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;
                 ^
../code.cpp:15:18: style: struct member 'has_A::foo' is never used. [unusedStructMember]
static const int foo = 8;
                 ^
../code.cpp:15:18: style: struct member 'is_A::foo' is never used. [unusedStructMember]
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).

Daniel Marjamäki f31fbba54a Token::typeDecl: Fix endless recursion for code:

I did not manage to pinpoint a good location to put a unit test. However this will be tested when daca@home runs the package gcc-avr.
