Api Symbols: replace asserts with checks ()
* Api Symbols: replace asserts with checks
* Api Symbols: replace asserts with checks part 2
* Update no args function signatures with void, to help compiler to track incorrect usage
* More unavoidable void
* Update PVS config and code to make it happy
* Format sources
* nfc: fix checks
* dead code cleanup & include fixes
