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().

Track lifetime across multiple returns
...
This will now warn when doing something like this:
```cpp
template <class T, class K, class V>
const V& get_default(const T& t, const K& k, const V& v) {
auto it = t.find(k);
if (it == t.end()) return v;
return it->second;
}
const int& bar(const std::unordered_map<int, int>& m, int k) {
auto x = 0;
return get_default(m, k, x);
}
```
The lifetime warning is considered inconclusive in this case.
I also updated valueflow to no tinject inconclusive values unless `--inconclusive` flag is passed. This creates some false negatives because library functions are not configured to not modify their input parameters, and there are some checks that do not check if the value is inconclusive or not.

Use library for memleak checks ( #2002 )
...
* Use library for memleak checks
Change memleakOnRealloc and leakReturnValNotUsed to use library
configuration instead of hardcoding "realloc".
In order to do so, some care needs to be taken when matching for a
reallocation function, since it can no longer be assumed that the input
to be allocated is the first argument of the function. This complicates
getReallocationType() and checkReallocUsage() but is necessary in order
to handle for example freopen() properly.
Also, refactor memleakOnRealloc check to reduce duplicated code when
checking "a" and "*a". When doing so, extending the check to look for
arbitrary number of "*" can be done for free (just change an if
statement to a while statement). Most likely, this is an unusual case in
real world code.

To be able to use real Qt-Code in "test/cfg/qt.cpp" and still do a
syntax check the Qt settings are read out via pkg-config now if it is
available. This way the test now can contain Qt macros and functions and
the syntax check can still be used.
Additionally the same options as for the other tests are used now for
the Qt config tests.
Installing the package "qtbase5-dev" should be enough to enable the
syntax checks (already installed for travis tests).

#4241 : Check for address of single character passed as string ( #1381 )
...
* #4241 : Check for address of single character passed as string
Add a check that address of a single character is not passed as argument
to argument marked as strings (using strz). The check does not warn if
the address of a character with known value '\0'.
Since ValueFlow currently does not handle global constants (see #7597 ),
do not warn if the variable is global to avoid FPs when the address of
a global variable assigned to '\0' is passed to a function expecting a
string.
Remove comment in docs saying strz is unused.
* Change asdf to Hello world
* Add test of address to first element in string
* Add error reporting function to getErrorMessages
* Fix strings in test
