Miscellaneous fix (#3750)

* Fix various compile warnings (on MSVC2005 and Android)

* A function declaration without a prototype is deprecated in all versions of C

* Fix build warning on VS2022

* Minor update on sample app pjsua2 for Android Kotlin: add param to avoid activity recreation in activity config changes, useful in maintaining video window sizes on orientation change.
