ra_dav Protocol for the trace_old_file_location Function

Hi!

The purpose of this E-mail is to suggest a protocol for the
trace_old_file_location function over WebDAV/DeltaV (to be implemented as a
client in libsvn_ra_dav and as a server in mod_dav_svn). The function will
use a REPORT request, with the following customized XML Body:

Wrapping XML Tag is <S:trace-old-node-location>.[1] It contains the tags:

1. <D:source>. This contains a <D:href> that contains the URL that needs to be
traced.

2. <S:peg-revision>. This contains the peg revision.

3. <S:past-revision>. This contains the past revision.

For example, a request to trace the old location at revision 5 of URL
http://localhost/svn/repos/myfile.txt at revision 28 will look like this:

<<<
<S:trace-old-node-url xmlns:S=\"[SVN_XML_NAMESPACE]" xmlns:D="DAV:">
<D:source><D:href>http://localhost/svn/repos/myfile.txt</D:href></D:source>
<S:peg-revision>28</S:peg-revision>
<S:past-revision>5/S:past-revision>
</S:trace-old-node-url>
>>>

In return we will get upon successful completion of operation the following
response:

<<<
<S:trace-old-node-url-report xmlns...>
<S:past-url><D:href>http://localhost/svn/repos/my-old-file.txt</D:href></S:past-url>
</S:trace-old-node-url-report>
>>>

Or a DAV error if the operation was not successful.
