Daniel Marjamäki f986380b14 Added test/testsuites folder
My idea with this folder is to collect external suitable test cases so we can test Cppcheck on these.

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)
Trac ticket #8994 was fixed in b222953bae.
Add a regression test to ensure it stays fixed.

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).

checkuninitvar.cpp: Use argument direction "out" info from library cfg (#1730)
CheckUninitVar::isMemberVariableAssignment uses argument direction "out"
now also to check for assignment when the member variable is handed over
to a function by reference.
testuninitvar.cpp: Improve tests, use a test library configuration.

versat df73f7f355 std.cfg, windows.cfg: Move strcpy_s from windows.cfg to std.cfg.
strcpy_s belongs to the standard so it must be in std.cfg instead of
windows.cfg.
Configuration for strcpy_s has been improved and tests were added.

Library configuration: function argument direction fixes and enhancements (#1722)
* std.cfg: Add further argument directions (in, out, inout).

* testlibrary.cpp: Add test for function argument direction configuration.

* std.cfg: runastyle and add some more direction configurations.

* library.h: Add documentation for function argument direction enum.

* Do not use "direction" library information for pointer arguments.

Also fix further unmatched uninitvar messages in std configuration
tests.

* std.cfg: Add more argument direction configurations.

* test/cfg/std.c: Add test for argument direction configuration.

* astutils.cpp: Only ignore pointer arguments for out/inout arguments.

* library.h: Use suggested documentation for argument direction enum.

Rikard Falkeborn 40ead7fd25 Add help to testrunner (#1704)
For now, only print the ways of running testrunner and the few options
that are available.

Also, refactor to remove an unneeded const_cast and use a range for loop.

Partially fixes #8514.
