fix for bug#8461

  BUG 8461 - TRUNCATE returns incorrect result if 2nd argument is negative
  Reason: Both TRUNCATE/ROUND converts INTEGERS to DOUBLE and back to INTEGERS
  Changed the integer routine to work on integers only.
  This bug affects 4.1, 5.0 and 5.1
  Fixing in 4.1 will need to change the routine to handle different types individually.
  5.0 did had different routines for different types already just the INTEGER routine was bad.

Fix for extra zero in exponent of double values on windows.


client/mysqltest.c:
  Write new function 'append_field' which takes care of appending one field to the dynamic string.
  Use function 'append_field' from both ps and normal execution
  Add hack to 'append_field' that removes the extra '0' in exponent for double values on Windows.

A query with a group by and having clauses could return a wrong
result set if the having condition contained a constant conjunct 
evaluated to FALSE.
It happened because the pushdown condition for table with
grouping columns lost its constant conjuncts.
Pushdown conditions are always built by the function make_cond_for_table
that ignores constant conjuncts. This is apparently not correct when
constant false conjuncts are present.

  In this case the corresponding EXPLAIN command now returns 
  "Impossible HAVING" in the last column.
