Nothing terribly exciting to see here.  I'm posting these patches just in case 
someone wants to comment or pick them up, because I won't be able to finish 
them today, or if Brane wants to take note because it's relevant to the 
property name testing in his recent prop-name spell-check code.

The attached 'property-name-test-functions-1.patch' creates some public 
functions:


 * subversion/include/svn_props.h
  (svn_prop_is_known_svn_rev_prop, svn_prop_is_known_svn_node_prop,
   svn_prop_is_known_svn_file_prop, svn_prop_is_known_svn_dir_prop): New
    functions.

and uses them in a small number of places that were doing those sorts of test 
in-line.

As I have written in the log msg, we might want to expose the arrays as well 
(or possibly instead of) the functions.


The attached 'propdel-suppress-nonexistent-1.patch' demonstrates what I was 
trying to do, which is make the following warnings go away:

$ svn pd svn:ignore -R contrib/cgi/
Attempting to delete nonexistent property 'svn:ignore' on 'contrib/cgi'
Attempting to delete nonexistent property 'svn:ignore' on 
'contrib/cgi/...svn.cgi'
Attempting to delete nonexistent property 'svn:ignore' on 
'contrib/cgi/...README'
Attempting to delete nonexistent property 'svn:ignore' on 
'contrib/cgi/...log.cgi'

I want the warnings to appear only for the node kinds where that property might 
be expected, not for all of the nodes.

My current approach of suppressing the notifications seems rather wrong.  As 
noted in the log message in the patch, I want tohave a look at what 'propset' 
does, as maybe we should be avoiding trying to delete it from the wrong node 
kind rather than trying and then suppressing the notification.

Or, perhaps the best solution is a middle way: try to delete from all nodes (I 
suppose we think we should do this "just in case it's there"), but don't send 
this notification when it's the wrong node kind.
