Comment (by iwakeh):

 Please review this
 [https://gitweb.torproject.org/user/iwakeh/collector.git/commit/?h=task-18910
 -first-sync-3&id=b998073dbf8ce8e6e728b6154b2b3ad8dcfc69ed third branch].

 It contains two minor commits and a large big one (on top).  The final
 sync functionality with disabled ReferenceChecker.

 I added tests for also checking the content of descriptor files.  Thus,
 the tests can now catch annotation issues.  To have one place for all
 annotation I introduced o.t.c.conf.Annotation, which at some point should
 become metrics-lib code.

 The persist package is corrected and the early line breaks in the paths
 descriptions are there for more readability.

 Files to 'recent' are first written to a temporary file and then renamed.

 The current paths obey the new path structure.  The way the paths are
 defined now it is an easy task to change the structure in case if
 necessary.

 I think it is better to have it in one commit as all things belong
 together and should be read and reviewed as a whole.

 Well, can't think of anything else right now.
