Misra false positive fixes for rules 8.7 and 5.9 (#3844) 
* Fix misra 8.7 false positives on single function usage

When there is a single usage of a function, we should first check if the
file it is used in, is the same one it was defined in. When this is not the
case, there is no violatior to be reported.

* Fix misra rule 5.9 false positives for exception

The exception for rule 5.9 described in the guidelines allows for
multiple definitions of internal linkage obejcts when these regard a
static inlined function defined in the same header file.

* Fix neglecting of inline keyword flag upon simplifications

When the inline keyword is being "simplified" and the inline flag is
degated to the next token. However, this information might be lost if the next
token itself is simplified/deleted in a futher pass. Therefore, we must
propagated the flag to all the next named tokens, so we can make sure the
function name token itself is tagged with this property.

* add tests for misra addon rules 8.7 and 5.9

Fix check for misra addon in executeAddons. (#3819) 
In the CppCheck::executeAddons function, a check that specifically tests
for the misra add-on, was not taking into account the cases when the
addon is identified with the '.py' extension or indirectly via json.
This resulted in the add-on not being executed a second time which is
needed to detected some of the misra violations. By using the AddonInfo
class name field, the addon name is uniformized for all these cases and
the add-on executed a second time.

Fix #10671: functionConst FN with begin/end and const_iterator (#3749) 
Check if the iterator is assigned to a const_iterator or
const_revese_iterator, in which case it is possible the function can be
const. Unfortunately, it is not possible to remove the hard coding of
cbegin, cend, crbegin and crend due to the need to handle auto, as in
the following code snippet:

    void cbegin_auto(void)
    {
        for (auto it = m_str.cbegin(); it != m_str.cend(); ++it) {;}
    }

Fix the ability to recognize return types when simplifying attributes. (#3637) 
* Fix the ability to recognize return types when simplifying attributes.

When parsing attributes to remove them, we have to allow for
the case where the return type of the function that follows
the attribute has a namespaced C++ type, like foo::bar .
That means that :: has to be recognized as a valid token.
Fix this in simplifyAttribute, and add tests for this as well.

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;
                 ^

                 ^

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().

Fix AST for brace initialization after decltype() (#3245) 
Currently sub-expressions like decltype(x){} break AST creation for
subsequent tokens in the whole expression. In some cases this triggers
validation checks in validateAst() and analysis on the file stops.
For example, code like this:
    int x = decltype(0){} ? 0 : 1;
currently produces internalAstError.

To fix the issue iscpp11init_impl() was changed to recognize { preceded
by decltype(expr) as a start of C++11 brace initialization expression.

Fixed #9729 (AST broken: lambda with noexcept keyword) (#3243) 
The previous fix for the issue (43b58dbc9e) didn't seem to actually fix
it because it added a check for noexcept without a condition, but when
AST is created noexcept always has a condition due to simplification
from "noexcept" to "noexcept(true)" in Tokenizer::simplifyKeyword().
The issue from the ticket couldn't be reproduced neither on 43b58dbc9e
nor on the previous commit, so it is hard to tell whether the fix was
effective or not.

The issue appeared again after a refactoring of AST code in ac67049661.
Test added with the original fix was unable to catch that because it
used testAst() helper function which skips most simplification steps.

To fix the issue we now check for noexcept with a condition and add a
proper regression test that:
1. Uses tokenizeAndStringify() to ensure that all simplifications are
   performed before AST is created.
2. Parses the code snippet from the ticket, as having "if (cond)" is
   crucial to reproducing the original issue (internalAstError).

Also fix AST creation for lambdas that have both constexpr and mutable
keywords.

Spotted by coverity (as the condition in the `if` part `isArrayVar(tok)`
dereferences tok.
Tok can't be null here, because the condition in the `else if`on line
268 checks that there is a `%var%` following, and
`tok = Token::findmatch(tok->next(), "%var%");` simply gets this `%var%`
token.

Fix varId assignment for uses of variables declared in the if condition (#3231) 
Variables declared in the if condition (or in C++17 init-statement) are
visible not only in the if body but also in the else body. But logic in
Tokenizer::setVarIdPass1() handled such variables as if they were
declared in the if body.

As the result they were removed from variablesMap by the time the else
block was parsed and their uses in the else block were either given an
incorrect varId from variables in some outer scope or not given a varId
at all.

This then resulted in false positive unreadVariable errors for variables
declared in the if condition (or init-statement) and used only in the
else block.

Simplification from "else if ..." to "else { if ... }" was moved before
setVarId() to simplify detection for ends of blocks in if-else chains.

Read error locations in the correct order from XML (#3226) 
When ErrorMessage::callStack elements are serialized to XML they are
saved in the reverse order. But when they read back from XML they are
added at the end of the list. Thus the round trip via XML reverses the
order of ErrorMessage::callStack.

From the user point of view it looks like the usage of the
--cppcheck-build-dir option sometimes (when the file wasn't reanalyzed,
but that is hard to spot) results in incorrect location info for some
diagnostic messages.

Moreover, when the first location matches some suppression rule and the
last doesn't match any (or vice versa), usage of --cppcheck-build-dir
results in some diagnostic messages appearing and disappearing seemingly
at random (again, depending on whether the file was reanalyzed or not).

partial revert of b1eaa3021f (#3174) 
It is necessary to use a fake NameAndToken in
mTypesUsedInTemplateInstantiation rather than a Token pointer so the
template simplifiers internal state is kept valid when tokens are
deleted. This prevents a use after free.

Fix tokenizing of x[i](0) (Fixes #8875) (#3167) 
Fix faulty removal of parenthesis when "]" is followed by parenthesis
with a number inside, for example when calling a function pointer in
an array or (perhaps more common) in c++, calling operator ( on an
element in an array.

Fixes #8875 where such wrong simplification lead to a FP with too many
bits shifted due to "<<" was interpreted like a shift operator rather
than a stream output.

Fix #10182 (FN memory leak with if-statement) (#3151) 
Improve leak detections in if-statements. This is done by checking
for leaks every time a scope is left. This allows cppcheck to catch
more memory leaks, as well as improve some error messages which now
contain the line where the variable goes out of scope, instead of the
end of the function.

Improve handling of realloc in memory leak checker (#3036) 
Mark realloced variables as realloced instead of freed. This allows
improved checking for code with error realloc handling.

If cppcheck finds an if-statement which checks the validity of the
allocated memory or resource, check if the memory/resource is
reallocated from another variable. If so, we can add checking of that
variable in the if-statement instead. This allows to check that variable
for memleaks and double frees.

This fixes #9292 and #9990 which both concern FPs with double frees
after correct error handling.

remove cleanupAfterSimplify from the template simplifier (#2998) 
The template simplifier works well enough now so cleanupAfterSimplify is
no longer necessary.  In fact cleanupAfterSimplify was introducing a bug
which improperly simplified C++ style casts.

Bugs should be exposed and fixed properly rather than just hiding them.

fix #9983 (TemplateSimplifier: template not simplified : f(0,0);) (#2905) 
Currently template type deduction for functions only works for single
template argument single function argument functions with a literal
argument.

This patch starts to add support for single template argument multiple
function argument functions.  It correctly handles functions with
multiple arguments of the same type. It also handles a mix of template
and non-template arguments.

It does not add support for overloading non-template arguments.
It does not add support for multiple parameter template functions.
It does not add support for type deduction from variable arguments.

Fix false positive memoryleak (#2882) 
```
int *f() {
  int *p = static_cast<int *>(realloc(nullptr, 10));
  if (!!(!p)) {
    return nullptr;
  }
  return p;

    return nullptr;

```
Because of the additional `!!̀ .

library: Add new warning: ignoredReturnErrorCode (#2877) 
* library: Add optional "type" attribute to "use-retval"

Added an optional "type" attribute to "use-retval" nodes in the
configuration. When the return type of a function configured with
`<use-retval type="error-code"\>` node does not used, the new style
error "ignoredReturnErrorCode" will be generated.

* Fix and improve patch after the initial review

* Fixed severity level and [[nodiscard]] attribute

* Fix incorrect condition

* Remove redundant condition
