Upgrade to 4.0 incorrectly sets request_method to 1 for all items

      Upgrade scripts seem to first set the default value of request_method to 1 and then to 0:

      grep -r request_method ./* 
./dbupgrade_3050.c: const ZBX_FIELD field = {"request_method", "1", NULL, NULL, 0, ZBX_TYPE_INT, ZBX_NOTNULL | ZBX_PROXY, 0}; 
./dbupgrade_3050.c: const ZBX_FIELD field = {"request_method", "0", NULL, NULL, 0, ZBX_TYPE_INT, ZBX_NOTNULL, 0};

      After a clean 3.4 DB was upgraded to 4.0 this is what that column contains:

      select request_method, count(*) from items group by 1;
+----------------+----------+
| request_method | count(*) |
+----------------+----------+
|              1 |     1656 |
+----------------+----------+

      This column is only used for http agent items, but is exported as non-default value for all items.
      It might also cause "unforeseen consequences" in future.
