Group support for cmocka

Last Friday I’ve released cmocka 0.4.0. It has several bugfixes and at least two new features. One is support for groups. This means you can define a setup and teardown function for a group of unit tests. I think some people have been waiting for this.

You can find an example here. It is simple and easy to use.
The other small feature is a new macro: assert_return_code(). It is designed for standard C function return values which return 0 for success and less than 0 to indicate an error with errno set. It will produce a nice error message! The rest are bugfixes and improvements for error message.

Thanks to all contributor and bug reporter!

If you think cmocka is a great piece of software, please vote it up on stackoverflow, thanks.
