Verify whether we can get rid of max value length by maintaining value length in value of index put about hindex HOT 3 OPEN

By using a known separator we can avoid the max value length. A 0 byte can be used as separator provided this will never come in the actual column data.

from hindex.

I will try this Anoop.

from hindex.

We can use 2 bytes (each 0 bytes) as separator. I believe that is good enough. In arbitrary column index, we no longer use max col value length and max index name length. We use separator there. Similar way we can handle other old cases also.

Old index data compatibility is one issue. The new way breaks old data compatibility. May be we will need some sort of tool which can convert old data to new format (?)
