We've added "efficient unprepare". The current API
isc_dsql_free_stmt() only supports DSQL_close (which
only closes a named cursor) and DSQL_drop (which
frees the statement handle). This change adds
DSQL_unprepare.

The api addition is:

#⁠define DSQL_close 1
#⁠define DSQL_drop 2
#⁠define DSQL_unprepare 4

Here is the code change for dsql/DStatement.cpp

ISC_STATUS DStatement::freeStatement(ISC_STATUS*
statusVector, int options)
{
ThreadData thread (statusVector, attachment);

try
{
if (options & (DSQL_close | DSQL_unprepare))
closeCursor();

if (options & (DSQL_drop | DSQL_unprepare))
{
closeStatement();
if (options & DSQL_drop)
delete this;
}
}
catch (OSRIException& exception)
{
return exception.copy (statusVector);
}

return 0;
}
