Ken-Patrick Lehrmann c297ed8204 Better handle noreturn or throwing functions in valueflow 
Teaching cppcheck about `BOOST_THROW_EXCEPTION` and
`boost::throw_exception`, and using noreturn information from libraries
in value flow.

This fixes false positive nullPointerRedundantCheck with the following
code:
```
void throwexception(int * buf)
{
    if (!buf)
        boost::throw_exception(std::bad_alloc());
    *buf = 0;
}
```

qt.cfg: #9650: Fix missing configuration for QString.chop() (#2556) 
chop() and also remove() change the size of a QString, so they have to
be added in the container configuration accordingly to avoid false
positives.

gtk.cfg: Fix syntax errors and false positives (#2552) 
A missing definition for g_assert_cmp*() causes syntax errors if code
like g_assert_cmpint(a, ==, b); is encountered.
The function g_hash_table_iter_replace() does not have to be marked
with leak-ignore since the memory could be freed later if corresponding
functions are present in the GHashTable. Since we can not know if this
is the case we have to assume that the memory is freed to avoid false
positives. The same is true for g_hash_table_insert() and
g_hash_table_replace().
