Use lazy initialization for Query_tables_list::sroutines hash.
This step should significantly decrease amount of memory consumed
by stored routines as we no longer will allocate chunk of memory
required for this HASH for each statement in routine.
include/hash.h:
Introduced auxillary hash_init_opt() macro which simplifies
lazy initialization of HASH objects.
sql/sp.cc:
Use lazy initialization for Query_tables_list::sroutines hash.
This step should significantly decrease amount of memory consumed

This step should significantly decrease amount of memory consumed

sql/sql_lex.h:
Updated comment describing Query_tables_list::sroutines to
reflect that now we are use lazy initialization for this hash.
Added constant for initial size of this hash.

It was possible for one thread to interrupt a Data Definition Language
statement and thereby get messages to the binlog out of order. Consider:
Connection 1: Drop Foo x
Connection 2: Create or replace Foo x
Connection 2: Log "Create or replace Foo x"
Connection 1: Log "Drop Foo x"
Local end would have Foo x, but the replicated slaves would not.
The fix for this is to wrap all DDL and logging of a kind in the same mutex.
Since we already use mutexes for the various parts of altering the server,
this only entails moving the logging events down close to the action, inside
the mutex protection.

sql/sp.cc:
Move logging inside the routine drop and update functions, so it can be
protected by a LOCK_open mutex. (The "create" function already had such
a LOCK_open protection.)
sql/sql_acl.cc:
Move logging inside the grant functions, so that it can be protected by
LOCK_grant .
sql/sql_db.cc:
Add comments that describe how each logging event is protected.
sql/sql_parse.cc:
Move all logging statements about DDL statements close to the actual event,
so each can be protected by the same mutex.
sql/sql_table.cc:
Widen the scope of the mutex so that logging events are also protected.
sql/sql_trigger.cc:

Move the logging statement inside the worker function, and notably inside
the LOCK_open mutex. Widen the same mutex a little to make room for logging.

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

The problem was that if after FLUSH TABLES WITH READ LOCK the user
issued DROP/ALTER PROCEDURE/FUNCTION the operation would fail (as
expected), but after UNLOCK TABLE any attempt to execute the same
operation would lead to the error 1305 "PROCEDURE/FUNCTION does not
exist", and an attempt to execute any stored function will also fail.
This happened because under FLUSH TABLES WITH READ LOCK we couldn't open
and lock mysql.proc table for update, and this fact was erroneously
remembered by setting mysql_proc_table_exists to false, so subsequent
statements believed that mysql.proc doesn't exist, and thus that there
are no functions and procedures in the database.
As a solution, we remove mysql_proc_table_exists flag completely. The
reason is that this optimization didn't work most of the time anyway.
Even if open of mysql.proc failed for some reason when we were trying to
call a function or a procedure, we were setting mysql_proc_table_exists
back to true to force table reopen for the sake of producing the same
error message (the open can fail for number of reasons). The solution
could have been to remember the reason why open failed, but that's a lot
of code for optimization of a rare case. Hence we simply remove this
optimization.
