* branches/issue-662-dev/:

Undo some of revision 2199, so most of "make check" passes again on
this branch.  Here's the plan:

Revision 2199 went most of the way to resolving issue #662 ("Use
notification callbacks, not composition editors, in libsvn_client
api").  But to get modules working (issue #517), we really only need
checkout, update, and possibly switch to be using the new notification
system; everything else can wait.  However, having gone so far on
#662, I didn't want to lose the work.  So it's all committed on
branches/issue-662-dev as revision 2199, after which I'm reverting as
much of it as necessary to make the tests pass again while still
giving us what we need for modules.

When it's time to merge that work into the trunk, the patch is 

   svn diff -r2198:HEAD http://svn.collab.net/.../branches/issue-662-dev

(I'm too lazy to figure out the `svn merge' command right now).  And
when it's time to complete issue #662, we can look at the reversions
on this branch since 2199 and figure out the best course.  Most likely
the easiest thing will be to peruse the log messages while looking at
this diff

  svn diff -rHEAD:2199

restore all the changes, then continue from there; but there may be a
better strategies when the time comes.

Anyway, after this semi-reversion, the following tests still fail:

   basic_tests.py 10: basic switch command
   update_tests.py 4: update to revision 0
   update_tests.py 5: make sure overlapping identical changes do not conflict
   switch_tests.py 1: test some basic switching operations
   switch_tests.py 4: reverse update wc that contains switched things
   switch_tests.py 6: reverse update switched wc things to an older rev

...Which sorta makes sense, considering that the notification changes
to updates and switches have not been reverted, because they're what
we actually want :-).

Here's what got undone:

* subversion/include/svn_client.h 
  (svn_client_import): Restore before and after editors, lose
  notify_func and notify_baton.
  (svn_client_commit, svn_client_copy): Restore before and after
  editors. 

* subversion/libsvn_client/copy.c, subversion/libsvn_client/commit.c:
  Revert revision 2199 to effect above header changes.

* subversion/clients/cmdline/cl.h
  (svn_cl__get_trace_commit_editor): Declare again.

* subversion/clients/cmdline/copy-cmd.c: Revert most of 2199, but
  leave the new opt_state->quiet handling.

* subversion/clients/cmdline/commit-cmd.c,
  subversion/clients/cmdline/import-cmd.c: Revert 2199. 

* subversion/clients/cmdline/trace-commit.c: Un-uncomment this file.

Remove some debugging code that is only useful when once again working
on issue 662:

* subversion/tests/clients/cmdline/svntest/actions.py
  (guarantee_greek_repository): Remove debugging prints.

* subversion/tests/clients/cmdline/svntest/main.py
  (run_svn): Remove alternate debug code.
