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.

misra-test.c: Add more tests for rule 10.1 (including FP and FN) (#2398)
Add some more tests for rule 10.1. They are given as examples in the
MISRA document. The 10.1 test that causes a false positive for 10.6 can be
found under the 10.6 tests.

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.

donate-cpu.py: Verify argument for jobs (-jN) (#2386)
Yesterday, I observed that some client with a wrong jobs setting
(only "-j") requested one package after another and always uploaded
results where it only said that the argument "-j" is invalid for
Cppcheck.
This check should avoid such cases where results are overwritten with
useless data and the server is kept busy for nothing.

Check for JSON error when parsing addon .json files + fixes (#2374)
* cppcheck.cpp: Check for JSON error when parsing addon .json files

This fixes that errors in JSON files given via `--addon=*.json` are
silently ignored and maybe only a part of the JSON file is used.
Now the error message which picojson can return is checked and a
corresponding error message is returned again by getAddonInfo().

* naming.json: Fix missing comma

* CLI: Fix naming violations detected by addon naming.py via naming.json

* Addon naming: Add argument for validating names of constants

* LIB: Rename functions/variables so they are valid, loosen naming rules

* GUI: Fix naming violations

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.

versat 0dd180d5a2 misra-test.cpp: Remove redundant unused function argument
The unused argument causes the new check for rule 2.7 to output an error
here.
I verified that the regression test still works without the unused
argument (misra.py would still crash).
Travis should be happy again.
