portability macro flags updates, for Haiku
some non-trivial changes to platform.h and util.h, initially related to compilation for Haiku, but I used this opportunity to make them cleaner and add some documentation. Noticed several tests that could be improved (too harsh conditions, useless exception, etc.) but I did not dare modifying too many tests just before release.dev
