SHOW 2012 INSTEAD OF 2011
* Added a new macro to hold the current year :
COPYRIGHT_NOTICE_CURRENT_YEAR
* Modified ORACLE_WELCOME_COPYRIGHT_NOTICE macro
to take the initial year as parameter and pick
current year from the above mentioned macro.

Various places in the server replication code was incorrectly quoting
strings, which could lead to incorrect SQL on the slave/mysqlbinlog.

Several fixes :
* sql-common/client.c
Added a validity check of the fields metadata packet sent
by the server.
Now libmysql will check if the length of the data sent by
the server matches what's expected by the protocol before
using the data.
* client/mysqltest.cc
Fixed the error handling code in mysqltest to avoid sending
new commands when the reading the result set failed (and
there are unread data in the pipe).
* sql_common.h + libmysql/libmysql.c + sql-common/client.c
unpack_fields() now generates a proper error when it fails.
Added a new argument to this function to support the error
generation.
* sql/protocol.cc
Added a debug trigger to cause the server to send a NULL
insted of the packet expected by the client for testing
purposes.

One of the reported problems manifested itself in the scenario when one
thread tried to to get statistics on a key cache while the second thread
had not finished initialization of the key cache structure yet.
The problem was resolved by forcing serialization of such operations
on key caches.
To serialize function calls to perform certain operations over a key cache
a new mutex associated with the key cache now is used. It is stored in the
field op_lock of the KEY_CACHE structure. It is locked when the operation
is performed. Some of the serialized key cache operations utilize calls
for other key cache operations. To avoid recursive locking of op_lock
the new functions that perform the operations of key cache initialization,
destruction and re-partitioning with an additional parameter were introduced.
The parameter says whether the operation over op_lock are to be performed or
are to be omitted. The old functions for the operations of key cache
initialization, destruction,and re-partitioning now just call the
corresponding new functions with the additional parameter set to true
requesting to use op_lock while all other calls of these new function
have this parameter set to false.
Another problem reported in the bug entry concerned the operation of
assigning an index to a key cache. This operation can be called
while the key cache structures are not initialized yet. In this
case any call of flush_key_blocks() should return without any actions.
No test case is provided with this patch.

There are two threads. In one thread, dml operation is going on
involving cascaded update operation. In another thread, alter
table add foreign key constraint is happening. Under these
circumstances, it is possible for the dml thread to access a
dict_foreign_t object that has been freed by the ddl thread.
The debug sync test case provides the sequence of operations.
Without fix, the test case will crash the server (because of
newly added assert). With fix, the alter table stmt will return
an error message.

WINDOWS
On shutdown(), Windows can drop traffic still queued for sending even if that
wasn't specifically requested. As a result, fatal errors (those after
signaling which the server will drop the connection) were sometimes only
seen as "connection lost" on the client side, because the server-side
shutdown() erraneously discarded the correct error message before sending
it.
If on Windows, we now use the Windows API to access the (non-broken) equivalent
of shutdown().
Backport from trunk
include/violite.h:
export mysql_socket_shutdown(). It lives in vio in the backport.
sql/mysqld.cc:
Go through our own shutdown() rather than straight to the POSIX one.
vio/viosocket.c:
Define mysql_socket_shutdown(). On UNIXoid systems, it's just a wrapper for shutdown(), but
on Window, it uses DisconnectEx, which is magic.

to work around the lack of a bzero() prototype.
include/m_string.h:
AIX does have bzero() in its system libraries,
and the configure phase detects it, including the prototype
(sets both HAVE_BZERO and HAVE_DECL_BZERO),
but the declaration is missing when the source is compiled.
Several attempts all failed.
This patch takes the brute force approach to always map
"bzero()" to "memset()" on AIX,
like is done on platforms where "bzero()" is not found at all.

UTF8_GENERAL_CI
Introducing new collations:
utf8_general_mysql500_ci and ucs2_general_mysql500_ci,
to reproduce behaviour of utf8_general_ci and ucs2_general_ci
from mysql-5.1.23 (and earlier).
The collations are added to simplify upgrade from mysql-5.1.23 and earlier.
Note: The patch does not make new server start over old data automatically.
Some manual upgrade procedures are assumed.
Paul: please get in touch with me to discuss upgrade procedures
when documenting this bug.

2. dialog plugin now always returns mysql->password if non-empty and the first question is of password type
3. split get_tty_password into get_tty_password_buff and strdup.
4. dialog plugin now uses get_tty_password by default
5. dialog.test
6. moved small tests of individual plugins into a dedicated suite

CREATE_TIME IN INFORMATION_SC
It was impossible to determine MEMORY table creation time,
since it wasn't stored/exposed.
With this patch creation time is saved and it is available via
I_S.TABLES.CREATE_TIME.
Note: it was decided that additional analysis is required before
implementing UPDATE_TIME. Thus this patch doesn't store UPDATE_TIME.
