* Removed -Wno-unused from all KernelMergeObjects in kernel Jamfiles.

* Fixed most of the warnings resulting from that by removing actually not used
  variables or moving declaration into the #IF. Left unused functions there
  though, as I wouldn't know if they are supposed to be used again.
* Fixed two statements with no effect (clamping to MAX_ANCILLARY_DATA_LEN in
  socket.cpp and unsetting fCounterSem in MessagingService.cpp).
* Some style cleanups.
