There was possible stack overrun in an edge case which handles invalid body of
a SP in mysql.proc . That should be case when mysql.proc has been changed
manually. Though, due to bug 21513, it can be exploited without having access
to mysql.proc only being able to create a stored routine.

doesn't find the column"

When a user was using 4.1 tables with VARCHAR column and 5.0 server
and a query that used a temporary table to resolve itself, the
table metadata for the varchar column sent to client was incorrect:
MYSQL_FIELD::table member was empty.

The bug was caused by implicit "upgrade" from old VARCHAR to new
VARCHAR hard-coded in Field::new_field, which did not preserve
the information about the original table. Thus, the field metadata
of the "upgraded" field pointed to an auxiliary temporary table
created for query execution.

The fix is to copy the pointer to the original table to the new field.

When a view was used inside a trigger or a function, lock type for
tables used in a view was always set to READ (thus making the view
non-updatable), even if we were trying to update the view.

The solution is to set lock type properly.

	InterfaceError on connect

Removed the bool flag from the st_mysql_options struct, since it adds 
another word in size to the memory size and shifts member memory locations
down, both of which break binary-interface compatibility.

Instead, use a flag, 2**30, in the client_options bit-field to represent
that the client should check the SSL certificate of the server.

erroneous check

Problem: Actually there were two problems in the server code. The check
for SQLCOM_FLUSH in SF/Triggers were not according to the existing
architecture which uses sp_get_flags_for_command() from sp_head.cc .
This function was also missing a check for SQLCOM_FLUSH which has a
problem combined with prelocking. This changeset fixes both of these
deficiencies as well as the erroneous check in
sp_head::is_not_allowed_in_function() which was a copy&paste error.

The following procedure was not possible if max_sp_recursion_depth is 0
create procedure show_proc() show create procedure show_proc;
  
Actually there is no recursive call but the limit is checked.
  
Solved by temporarily increasing the thread's limit just before the fetch from cache
and decreasing after that.

 Must not use Item_direct_ref in HAVING because it points to
 the new value (witch is not yet calculated for the first row).

Changed trigger-handling code so that there will be the one
place for generate statement string for replication log
and for trigger file.

    
User name (host name) has limit on length. The server code relies on these
limits when storing the names. The problem was that sometimes these limits
were not checked properly, so that could lead to buffer overflow.
  
The fix is to check length of user/host name in parser and if string is too
long, throw an error.

Changes in an item tree done by optimizer weren't properly
registered and went unnoticed, which resulted in preliminary freeing
of used memory.
