* Renamed fs/vfs_select.cpp to wait_for_objects.cpp and got rid of

vfs_select.h, respectively moved most of it into the new kernel
  private header wait_for_objects.h.
* Added new experimental API functions wait_for_objects[_etc](). They
  work pretty much like poll(), but also for semaphores, ports, and
  threads.
* Removed the "ref" parameter from notify_select_events() and the
  select_sync_pool functions as well as from fd_ops::fd_[de]select(). It
  is no longer needed. The FS interface select() hook still has it,
  though -- the VFS will always pass 0.
* de]select_fd() take a select_info* instead of a select_sync* + ref
  pair, now. Added respective functions for semaphores, ports, and
  threads.
