Any default value for a enum fields over UCS2 charsets was corrupted
when we put it into the frm file, as it had been overwritten by its
HEX representation.
To fix it now we save a copy of structure that represents the enum
type and when putting the default values we use this copy.

 VALUES() was considered a constant. This caused replacing

 execution takes place.
 Mark it as a non-constant (still not dependent of tables) to prevent
 the pre-calculation.

            1003: Incorrect table name
in multi-table DELETE the set of tables to delete from actually 
references then tables in the other list, e.g:
DELETE alias_of_t1 FROM t1 alias_of_t1 WHERE ....
is a valid statement.
So we must turn off table name syntactical validity check for alias_of_t1 
because it's not a table name (even if it looks like one).
In order to do that we add a special flag (TL_OPTION_ALIAS) to 
disable the name checking for the aliases in multi-table DELETE.

The problem was due to a prior fix for BUG 9676, which limited
the rows stored in a temporary table to the LIMIT clause. This
optimization is not applicable to non-group queries with aggregate
functions. The fix disables the optimization in this case.

	event' from master"

Since there is no repeatable test case, and this is obviously wrong, this is
the most conservative change that might possibly work.  

The syscall  read()  wasn't checked for a negative return value for an
interrupted read.  The kernel  sys_read()  returns -EINTR, and the "library" 
layer maps that to return value of -1 and sets  errno  to EINTR.  It's 
impossible (on Linux) for  read()  to set errno EINTR without the return 
value being -1 .

So, if we're checking for EINTR behavior, we should not require that the
return value be zero.


mysys/my_read.c:
  The read() syscall should check for negative one, since that (usually) signals
  errors (like being interrupted) and zero (usually) signals end-of-file .
