* Clean up introductory comments for hook handler declarations, explain about
  RUN_ALL, RUN_FIRST in one single place, remove leftover comments from 1.3
* Place trace entry for quick_handler in request context
* Found every hook declaration in the source by running 

  find . -name \*.[ch] | xargs grep -E -A 3  \
    "AP_IMPLEMENT_(OPTIONAL_|)HOOK_(VOID|RUN_ALL|RUN_FIRST)"
  
  from top of source tree; implemented handler for everything that turned
  up. 

Next up: bring comments in line with introduction, clean up existing comments; 
re-design trace mechanism to stop messing with globals after server may
start threads.

decision as to how it will allocate the tasks of writing to the
cache and writing to the network. Previously the write to the

written to the network, and this caused timing and memory issues
on large cached files. This fix replaces the previous fix for
