Security: Tighten DynamicLinker*, NativeLibrary and DynamicLibraryBundle access (2)

- Completes 23341a2df2d2ea36784a16fa1db8bc7385351a12

- Replace 'DynamicLinker' interface w/ well documented one

- All DynamicLinker methods are now considered secure, i.e.:
  - open/lookup and close utilize reference counting on handle via a hash map.

  - lookupSymbol(..) and close(..) impl. validate the passed library handle
    whether it's retrieved via open*.
    This is the fast path, not that expensive.

  - lookupSymbolGlobal(..) performs
    Check acccess of 'new RuntimePermission("loadLibrary.*")' if SecurityManager is installed.
    This is the slow path.

- DynamicLibraryBundleInfo now reflects the security requirements,
  i.e. whether priviledged access is needed.
