the tag table should be of type int* not tag*.

This bug resulted in rsync being much less efficient that it could be
for files with more than 64k blocks. With the adaptive block size code
giving a maximum block size of 16k this means that files larger than
1GB were handled very inefficiently. The transfer was still accurate,
just slow.
