use LOG_ABORT not just abort()

* abort() has the unfortunate effect that nothing is seen in the log,
  just an event (which is usually not displayed); so ops people don't
  see that the program is crashing at all.
* LOG_ABORT("message") will log an error with the message (and the file
  and line) before calling abort(), so it's easy to see what happened.
* add or move <vespa/log/log.h> include and LOG_SETUP lines before
  LOG_ABORT is used (or included).
