Portability fix (Got different results for double -> longlong when compiling with full optimization)

Now simply give an error if no database. (The "global SP feature" will be
done using PATH instead.)

  Added a test case for bug #5896.
sql_select.cc:
  Fixed the problem of ignoring on expressions depending
  only on outer table when outer table either contains
  1 row or is guaranteed to return only 1 row (bug #5896).

More tests.
Better error messages.
Fixed bug when checking if we updated all needed columns for INSERT.
Give an error if we encounter a wrong float value during parsing.
Don't print DEFAULT for columns without a default value in SHOW CREATE/SHOW FIELDS.
Fixed UPDATE IGNORE when using STRICT mode.

Under strict mode MySQL will generate an error message if there was any conversion when assigning data to a field.

In binary log events, flags are 2 bytes, not 4. Using 4 resulted in buffer overflow (and on a certain build it resulted in overwriting another part of the event without crashing :( ).

privilege checking is not in place yet.

We should not replace Item_arena in Item_bool_func2::fix_length_and_dec() if this is
conventional statement, since in this case THD::current_arena is the same as active arena
and we will overwrite arena with its older version during restore_backup_item_arena()
call.

Removed wrong warnings in test suite (This was because select_insert / select_create results was not freed.
Added thd to openfrm() for initialization of TABLE->in_use. This fixed a bug in BDB handling where table->in_use was used early

now we allow to careate VIEW without any privileges on view columns (except create view privilege) (BUG#5152)
