Negate APLOGctrace7(c) test!

Also, return DECLINED when nothing is to be done, same result as OK but

  (doRotate): Use apr_psprintf() and %pm.  Move the destruction of the pool

  (doRotate): Add code that knows how to create the directories a log file
    is going to go into.
  (main): Add the -d option and canonicalize the incoming path with
    apr_filepath_merge() so that the code in doRotate can work properly.

Submitted by: Philippe Lantin <plantin cobaltgroup.com>
              (which was actually a patch written by myself when I worked there)
Tweaked by: breser (ported to trunk and changed option from -p to -d)



Followup to r1533810: Put the rotatelogs docs in the right place.

* docs/man/rotatelogs.8,
  docs/manual/programs/rotatelogs.html.en: Remove changes from r1533810.

* docs/manual/programs/rotatelogs.xml: Adjust docs for new -d option. 


Choose "-D" instead of "-d" for the rotatelogs
option that creates the path to the log file.

I want to use "-d" for another directory related
option next where (I think) the "directory" "d"
makes more sense.

"-d" has not yet been backported, so changing
to "-D" is not a real compatibility issue.
