- getAddonFilePath is used with getDataDir, this works fine
for a local build cppcheck, but not for a system installed one.
As getDataDir reports the location relative to the executable (/usr/bin/)
and the addons are localed in FILESDIR (/usr/share/cppcheck).
Extend the search path by FILESDIR/addons to also make it work for
the installed cppcheck version.
The filename of the daily built installer still contains 2.0 e.g.:
cppcheck-2.0.182-x64-Setup.msi
- Read the ProductVersion from productInfo.wxi and use it in the
file name of the cppcheck setup file.

- Fix indentation, yamllint error:
10:5 error wrong indentation: expected 6 but found 4 (indentation)
* Include detecting variadic template functions by matching against endTok instead of startTok.
* Add argument count check for variadic (template) member functions.
Also fix a broken test case related to checking the return value -1
where socket was not defined in the library used in the tests.
This was tested running test-my-pr with 500 packages. The difference was
six fewer FPs.
* Tokenize: Set varId for variables in enum
Set varIds in enum values. It was previously disabled in 5119ae84b8
to avoid issues with enums named the same as global variables. Take care
to only set varids to variables used to set the value of an enumerator,
not the enumerator itself. This is somewhat complicated by the fact that
at the time this happens, astOperand1(), astOperand2(), astParent() etc
are not set. The current implementation is not perfect, for example in
the code below, y will not have a varid set, but x and z will. This is
deemed sufficient for now.
int x, y, z;
enum E { a = f(x, y, z); };
* Fix#9647: Value of enums with variables as init values
C++ allows enum values to be set using constexprs, which cppcheck did
not handle before. To solve this, add a new pass to valueflow to update
enum values after global consts have been processed. In order to do so,
I moved all settings of enum values to valueflow. After setting the enum
values, we need another call to valueFlowNumber() to actually set users
of the enums.
There is still room for improvements, since each pass of
valueFlowGlobalConstVar() and valueFlowEnumValue() only sets variables
that are possible to set directly, and not if setting the value of a
variable allows us to set the value of another. For example
constexpr int a = 5;
constexpr int b = a + 5;
enum E { X = a };
constexpr E e = X;
Here both b and e will not have their values set, even though cppcheck
should be possible to figure out their values. That's for another PR
though.
This was tested by running test-my-pr.py with 500 packages. The only
difference was one error message in fairy-stockfish_11.1, where cppcheck
now printed the correct size of an array instead of 2147483648 which I
assume is some kind of default value. In that package, using a constexpr
when setting enum values is common, but as mentioned, there was no
change in the number of warnings.
