- adding _actual as a suffix only for calls to an actual proc and not through a global function pointer - fixes https://github.com/nim-lang/Nim/issues/11996 (#12007)

- adding forward declarations for reloadable functions within a module - fix compilation errors when 2 such functions reference each other - fixes https://github.com/nim-lang/Nim/issues/11608
- preserve permissions of copied executable binaries
