* Added a mechanism to retrieve a BMessage with eventual error descriptions

for _kern_load_image().
* Added KMessage to the runtime_loader (a bit hacky, though) - it will use
  it to deliver the above mentioned functionality.
* load_dependencies() did return the wrong status code in case a library
  was missing; now it returns B_MISSING_LIBRARY.
* load_dependencies() will now try to load all dependencies when a report
  message is requested; therefore, all missing libraries are listed.
* Renamed uspace_program_args to user_space_program_args.
* The kernel filled in various members of the user_space_program_args structure
  unsafely, ie. was not using user_memcpy().
* Renamed some local variables in team.c to better fit our style guide (ie.
  uargs to userArgs).
* Changed Tracker to use the new _kern_load_image() variant on Haiku to retrieve
  and report all missing libraries. This fixes bug #1324.
* Adapted kernel_cpp.cpp to the runtime loader as well; the latter will now
  compile with _LOADER_MODE defined.
