code-style: general cleanups (#137)

* tns_clean_cache: remove unused function arg

* remove malloc casting

* improve consistency

use sizeof(T) at the end

* avoid comparing integers of different signedness

* use Window type for embed and parent

* remove unnecessary comparisons

* remove cpp style comments

* improve consistency: remove comma from the end of enumerator list

* Removed useless _IMAGE_CONFIG defines

* consistency: use the same order as snprintf

* Resolve c89 warnings
