continue to update it at make-time.

One shouldn't need to run "make" on server source to get the stuff we say
plugins should use.

Unknown timezone specifications are properly rejected
by the server, but are copied into tz_storage before
rejection, and hence is retained until end of server 
life. With sufficiently large bogus timezone specs, 
it is easy to exhaust system memory.
      
Allocation of memory for a copy of the timezone
name is delayed until after verification of validity,
at the cost of a memcpy of the timezone info. This 
only happens once, future lookups will hit the cached
structure.

for bug #41486. Session max_allowed_packet is read-only
as of MySQL 5.1.31. In addition, the global variable
now has no effect on the current session.

fixed help message

Don't throw an error after checking the first and the second arguments.
Continue with checking the third and higher arguments and if some of
them is stronger according to coercibility rules,
then this argument's collation is set as result collation.

                        
When loading dump created by mysqldump tool an error is
thrown saying storage engine for the table doesn't have 
an option.
                        
mysqldump tries to re-insert the data into the federated
table which causes the error. Since the data is already
available on the remote server, mysqldump shouldn't try
to dump the data again for FEDERATED tables.
                        
As stated in the bug page, it can be considered similar
to the MERGE ENGINE with "view only" nature.
                        
Fixed by adding the "FEDERATED ENGINE" to the exception
list to ignore the data.

smarter, and according to a contributer, it is necessary for plugin authors
using "--with-debug".

mysql.procs_priv table itself does not get replicated.
Inserting routine privilege record into mysql.procs_priv table
is triggered by creating function/procedure statements
according to current user's privileges.
Because the current user of SQL thread has GLOBAL_ACL,
which doesn't need any check mysql.procs_priv privilege
when create/alter/execute routines.
Corresponding GLOBAL_ACL privilege user
doesn't insert routine privilege record into
mysql.procs_priv when creating a routine.

Fixed by switching the current user of SQL thread to definer user if
the definer user exists on slave.
That populates procs_priv, otherwise to keep the SQL thread
user and procs_priv remains unchanged.
