...
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.

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
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.

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.

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).
