versat 0d14bdac22 windows.cfg: Add "buffer-size" attributes, fix allocation configuration.
Memory allocated with `_aligned_*malloc*()` must be freed with

See
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/aligned-malloc
for details.
Also add tests for some of the changed functions.

Library: Enhance minsize configuration and allow simple values. (#1736)
Some POSIX and Windows functions require buffers of at least some
specific size. This is now possible to configure via for example this
minsize configuration: `<minsize type="value" value="26"/>`.
The range for valid buffer size values is 1 to LLONG_MAX

versat 6f7612de03 boost.cfg: Add argument directions; some fixes; rearrange and document.
- Remove redundant function configurations for the same function since
it is not (yet) possible to configure overloaded functions. Instead mark
the optional arguments with `default="0"` so the configuration works
with a different number of arguments.
- Add documentation to boost.cfg (links and function declarations).
- Rearranged configurations so functions, defines, ... are together now.
- Add `direction` for function arguments where applicable.
- Add some tests to boost.cpp.

Daniel Marjamäki 729f57d8f1 Start a major rewrite of CheckBufferOverrun. For now only the 'array index' and 'buffer overflow' checks are rewritten.
There are important TODOs still; for instance adding CTU support using our CTU infrastructure, add handling of pointers (maybe I'll use FwdAnalysis for this), add handling of multidimensional arrays, etc..

Rikard Falkeborn a4269042e8 Add regression test for #8994 (#1733)

Rikard Falkeborn 6a3dd9a185 Handle concatenated string and char literals
This handles concatenated strings and characters from simplecpp.
Previously, L'c' would be preprocessed to the tokens  "L" and "'c'".
cppcheck would then remove the "L" token and set "'c'" to be a wide
character literal. Now, it needs to remove the prefix instead.

When doing this, add handling of utf32 encoded literals (U) and UTF-8
encoded literals (u8).

Paul Fultz II fd3c1fd040 Fix issue 1777: Undefined Behavior: Comparing pointers to different objects
This uses the lifetime analysis to check when comparing pointer that point to different objects:

```cpp
int main(void)
{
    int foo[10];
    int bar[10];
    int diff;

    if(foo > bar)   // Undefined Behavior
    {
       diff = 1;
    }

    return 0;
}
```

Paul Fultz II 507c7a4388 Improvement to lifetime tracking of addressof and derefencing
This will now warn for cases like this:

```cpp
auto& f() {
    std::vector<int> x;
    return x[0];
}
```

It also improves the handling of address of operator, so it can now warn across some function calls, like this:

```cpp
int& f(int& a) {
    return a;
}
int* hello() {
    int x = 0;
    return &f(x);
}
```

Kamil Dudka 2908593cf6 checkautovariables: eliminate false positives on assignment of &ptr->item (#1667)
Even if `ptr` is a local variable, the object `ptr->item` might be not.
So taking address of `ptr->item` is definitely not unsafe in general.

This commit fixes false positives triggered by commit
1.85-249-gf42648fe2 on the following code of sssd:

Paul Fultz II cf1ad5087a Extend constStatement checker
This reworks constStatement to find more issues. It catches issue [8827](https://trac.cppcheck.net/ticket/8827):

```cpp
extern void foo(int,const char*,int);
void f(int value)
{
        foo(42,"test",42),(value&42);
}
```

It also catches from issue [8451](https://trac.cppcheck.net/ticket/8451):

```cpp
void f1(int x) {
    1;
    (1);
    (char)1;
    ((char)1);
    !x;
    (!x);
    ~x;
}
```

And also:

```cpp
void f(int x) {
    x;
}
```

The other examples are not caught due to incomplete AST.

rikardfalkeborn dc4e7cef88 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'.
