New default warning message format

[Daniel Marjamäki]

I wonder if you have some opinions about changing the default message format for warnings. I think it should use --template=gcc by default. We can add a --template=cppcheck option to get the current output.

The biggest question imho is how this will affect the plugins and scripts.

If there is a script/plugin that need to parse the output then I think --xml should be used. The default textual output is not well suited for that.

If there is a script that runs cppcheck and just output the warnings then it will behave differently. But I think it will be better.

Actually, I always set --template=gcc so having it be default would be nice. Although, it doesnt work well when using the -j flag as shown in this issue:

It seems like this issue should be fixed before we make it the default.

I went ahead and changed the format now. I agree that ticket should be fixed. I also see some new problems with samples/memleak - the issue is not detected and it seems very strange if that somehow is caused by the changed template.
