[PATCH] consistent out-of-date handling by commit

Hi folks,

Here is a patch that resolves issue #2740 ("out-of-date" error text
varies depending on access method) and plugs a loophole in the commit
safety net, as far as tree conflict detection is concerned.

I mentioned this patch in an earlier email about the behavior of merge
(http://svn.haxx.se/dev/archive-2008-02/0872.shtml). Our current tree
conflict detection scheme relies on this patch, but this patch is not
specific to tree conflicts.

Regards,
Steve

Subversion should cancel a commit that includes the deletion of a file
or directory that has already been deleted in the repository.

When cancelling a commit that tries to delete or modify a file or dir
that has already been deleted in the repo, the "out of date" error
message should be consistent for all remote access methods (v. issue
#2740).

* subversion/libsvn_client/commit_util.c
   (out_of_date): New function.
   (do_item_commit): To give the user an "out of date" error instead of
    "not found", replace SVN_ERR() with manual error handling when
    asking the repo to delete dirs or files, to open files, or to
    receive property deltas during commit.

* subversion/libsvn_client/commit.c
   (svn_client_commit4): Give the user an "out of date" error instead
    of "not found", if the RA editor can't be initialized.

* subversion/libsvn_ra_serf/commit.c
   (delete_entry): Treat the response '404 Not Found' as an error.

* subversion/libsvn_ra_neon/commit.c
   (commit_delete_entry): Treat the response '404 Not Found' as an error.

* subversion/libsvn_repos/commit.c
   (out_of_date): Extend for case where we don't know the node type
    because the node does not exist.
   (delete_entry): If a path is not found, return an error.

* subversion/tests/cmdline/commit_tests.py
   (commit_out_of_date_deletions): Extend test cases to include all
    relevant combinations of deletion vs (property-change | text-change |
    deletion). Use svntest.actions.run_and_verify_commit consistently.
