Sebastian fd900ab8b2 testnullpointer.cpp: Add test for dereferencing returned NULL pointer (#2401) 
This adds a regression test to make sure that directly dereferencing a
returned NULL pointer issues a warning.
This has been asked on Stack Overflow:
https://stackoverflow.com/q/58981369
Cppcheck 1.89 does not warn for such a code, but 1.90 dev does. So it
is a good idea to make sure it is detected in the future too I guess.

Fix #9478: Valueflow: printf does not change value (#2388) 
Format-string arguments are now marked to have `in` direction, except
for `scan`-functions (like `scanf`) where these arguments are explicitly
marked to have `out` direction.

Rikard Falkeborn f6a2034a4c Add regression tests for fixed crashes (#2379) 
The invalid code in Trac tickets #8750, #8753, #8756, #8762, #8764
and #8765 previously crashed cppcheck. Now it throws a syntax error
instead. Add some tests for these tickets.

IOBYTE 3a617fa04a Fix #9472 (Syntax error on valid C++ code) (#2363) 
There are probably a lot more valid code patterns that generates syntax
errors so I added "operator" to the error message to make it easier to
find them.
