[SVN-4476] Mergeinfo containing r0 makes svnsync and dump and load fail

Description

svnsync errors out on trying to sync a revision that adds or changes a mergeinfo property containing a reference to revision number 0.

Such mergeinfo is now considered invalid, and cannot be committed with recent servers, but can be committed through a server older than 1.6.18 for HTTP or older than 1.6.17 for the other protocols. See issue SVN-3895 "repos layer does not verify mergeinfo syntax".

In addition, svnadmin dump errors out when it tries to dump such a property, iff any non-zero start revision is specified for the dump.

I have confirmed this, testing by hand, using Subversion v1.7.16 and v1.8.8.
