Fix prepared statement (#734)

* Fix prepared statement

When there are many args and maxAllowedPacket is not enough,
writeExecutePacket() attempted to use STMT_LONG_DATA even for
0byte string.
But writeCommandLongData() doesn't support 0byte data. So it
caused to send malfold packet.

This commit loosen threshold for using STMT_LONG_DATA.

* Change minimum size of LONG_DATA to 64byte

* Add test which reproduce issue 730

* TestPreparedManyCols test only numParams = 65535 case

* s/as possible//
