Fix Description: The print_changelog function in dbscan.c expects all
have 0x05 as the first byte, which signifies the changelog version.
check should be done for all change entries in the changelog db, but
three special entries that are in the beginning of the changelog where
apply. These entries are an entry count, the purge RUV, and the max RUV.
It should be noted that these entries are not always present when the
running, so dbscan will often work fine against a running server.
server is stopped gracefully, these entries are flushed out to be used
server is restarted.
The attached diffs make dbscan check for these special entries when
through a changelog. If it encounters one of these entries, it will
the data in a nice usable format.
