Empty CMAKE_BUILD_TYPE is not equal to Debug build and can lead to
missing debug symbols. Since cmake also non build configurations it's
better to set RELEASE definition by CONFIG generator expression.

* Implement aufile_set_position

* Take wav header into account, thanks @cspiel1

Also observe max column length of 80.

* Fix more linter warnings.

* Fix compilation errors on Windows (fingers crossed)

* One more Windows error fixed

* Fix doxygen comment

* Remove obvious comment

* int as return type for aufile_set_position (doh)

* Do review comments from @alfredh

* Use size_t in aufile_set_position
