server,mysql: support server-side cursors ( #6648 )
...
Implement server-side cursors by handling COM_STMT_FETCH command.
The client indicates that it wants to use cursor
by setting a flag in COM_STMT_EXECUTE
Please refer to https://dev.mysql.com/doc/internals/en/com-stmt-execute.html
Subsequently, the client acquires result rows repeatedly by COM_STMT_FETCH,
which will carry stmt-id and fetch size.
Please refer to https://dev.mysql.com/doc/internals/en/com-stmt-fetch.html
This commit only support forward-only, read-only cursor

plan: change the value of descScanFactor ( #6812 )
...
change the value of descScanFactor to make it compatible with tikv due to pingcap/tikv#3124 .
Now, if each row has only one version, the reverse scan's performance is near the performance of the speed of scan. If there's a lot of version, it will become about 1.8x than scan.
So we decrease the factor from 5 to 2.
