Correct Zero/Null as pointer constant ( #1938 )
...
Building with enhanced clang warnings indicated a large number of
instances with the warning:
`warning: zero as null pointer constant`
Recommended practice in C++11 is to use `nullptr` as value for
a NULL or empty pointer value. All instances where this warning
was encountered were corrected in this commit.
Where warning was encountered in dependency code (i.e. external library)
no chnages were made. Patching will be offered upstream.

Fix issue 9006: False positive: Return value of function std::move() is not used.
...
This is trying to fix the issue by fixing the ast and symbol database. First, the ast nodes will be created for the init list and the symbol database will not mark it as a scope. I am not sure if this is the correct approach as I dont really understand how the AST part works.
It did change the AST for `try {} catch (...) {}` but that is because it incorrectly treats `try {}` as an initializer list.

Run simplifyPlatformTypes on library return types ( #1672 )
...
Add a call to simplifyPlatformTypes() in
SymbolDatabase::setValueTypeInTokenList() to simplify return types of
library configured functions. This fixes the FN in #8141 . Regression
tests are added, both for the original issue and another FN in the comments.
In order to do that, move simplifyPlatformTypes() to TokenList from Tokenizer.
This is a pure refactoring and does not change any behaviour. The code was
literally copy-pasted from one file to another and in two places
'list.front()' was changed to 'front()'.
When adding the call to simplifyPlatformTypes(), the original type of
v.size() where v is a container is changed from 'size_t' to 'std::size_t'.
Tests are updated accordingly. It can be noted that if v is declared as
'class fred : public std::vector<int> {} v', the original type of 'v.size()'
is still 'size_t' and not 'std::size_t'.

isVariableDeclaration: Handle pointer to const pointer ( #1395 )

isVariableDeclaration did not handle pointer to const pointer, or
pointer to volatile pointer. This resulted in FPs in examples like the
following:
class Fred {
public:
const char *const *data;
const char *const *getData() { return data; };
}
where cppcheck would say getData could be static, since it didn't
recognize const char *const *data as a variable declaration.

symboldatabase: Fix potential null pointer dereference ( #1072 )
...
There is a potential `nullPointer` dereference in symboldatabase. This PR attempts to fix this. Additionally, this could be detected by Cppcheck as well.
Here is a reduced and compilable testcase, where Cppcheck fails to detect a potential `nullPointer` dereference:
```
class Scope
{
public:
bool bar();
int *definedType;
};
int f(Scope *new_scope)
{
int ret = 1;
if (new_scope)
{
if (new_scope->bar())
{
if (!new_scope->definedType) {} // check for null
ret = *new_scope->definedType; // dereference
}
}
return ret;
}
```

Add support for simple c++ 11 type ailases like: using INT = int; ( #1024 )

* Add support for simple c++ 11 type ailases like: using INT = int;
Only types supported by ValueType are supported. Complex types like
function pointers are not supported. Template type aliases are not
supported.
* Fix crash when type in using type alias is simplified away.
This fixes a crash when size_t is replaced with unsigned long in: using
size_t = unsigned long; by the tokenizer.
This does not fix the problem where Tokenizer::simplifyPlatformTypes()
simplifies away size_t in other cases. This is only a problem when the
new type is different from the platform type.
