The patch fixes a build problem on MacOSX, where
the compiler complains about unused parameters.

Valgrind warning happens due to missing NULL value check in
Item::get_date. The fix is to add this check.

Valgrind warning happens because null values check happens too late
in Item_func_month::val_str(after result string calculation).The fix
is to check null value before result string calculation.

ASSERTION TABLE->DB_STAT FAILED IN
SQL_BASE.CC::OPEN_TABLE() DURING I_S Q

This assert could be triggered if a statement requiring a name
lock on a table (e.g. DROP TRIGGER) executed concurrently
with an I_S query which also used the table.

One connection first started an I_S query that opened a given table.
Then another connection started a statement requiring a name lock
on the same table. This statement was blocked since the table was
in use by the I_S query. When the I_S query resumed and tried to
open the table again as part of get_all_tables(), it would encounter
a table instance with an old version number representing the pending
name lock. Since I_S queries ignore version checks and thus pending
name locks, it would try to continue. This caused it to encounter
the assert. The assert checked that the TABLE instance found with a
different version, was a real, open table. However, since this TABLE
instance instead represented a pending name lock, the check would
fail and trigger the assert.

This patch fixes the problem by removing the assert. It is ok for
TABLE::db_stat to be 0 in this case since the TABLE instance can
represent a pending name lock.

Test case added to lock_sync.test.

Issue:
======
Test case Correction for bug#11751148.

Valgrind warning happens due to missing NULL value check in
Item_func::val_decimal. The fix is to add this check.

Valgrind warning happens due to uninitialized cached_format_type field
which is used later in Item_func_str_to_date::val_str method.
The fix is to init cached_format_type field.

Fixed RelWithDebugInfo bzr ignores.

Bug #11766769

The LGPL license is used in some legacy code, and to
adhere to current licensing polity, we remove those
files that are no longer used, and reorganize the
remaining LGPL code so it will be GPL licensed from
now on.
      
Note:  This patch only removed LGPL licensed files
       in MySQL 5.1, and is the second of a set of
       patches to remove LGPL from all trees.
       (See Bug# 11840513 for details) 

Assert fails due to overflow which happens in
Item_func_int_val::fix_num_length_and_dec() as
geometry functions have max_length value equal to
max_field_size(4294967295U). The fix is to skip
max_length calculation for some boundary cases.

Assertion happens due to missing initialization of unsigned_flag
for Item_func_set_user_var object. It leads to incorrect
calculation of decimal field size.
The fix is to add initialization of unsigned_flag.

Valgrind warining happens due to missing
'end of the string' check. The fix is to
check if we reached the end of the string.

Problem: mysqlbinlog --server-id may filter out Format_description_log_events.
If mysqlbinlog does not process the Format_description_log_event,
then mysqlbinlog cannot read the rest of the binary log correctly.
This can have the effect that mysqlbinlog crashes, generates an error,
or generates output that causes mysqld to crash, generate an error,
or corrupt data.
Fix: Never filter out Format_description_log_events. Also, never filter
out Rotate_log_events.

ARE NOT BEING HONORED

max_allowed_packet works in conjunction with net_buffer_length.
max_allowed_packet is an upper bound of net_buffer_length.
So it doesn't make sense to set the upper limit lower than the value.
Added a warning (using ER_UNKNOWN_ERRROR and a specific message)
when this is done (in the log at startup and when setting either 
max_allowed_packet or the net_buffer_length variables)
Added a test case.
Fixed several tests that broke the above rule.

  
The slave was not able to find the correct row in the innodb
table, because the row fetched from the innodb table would not
match the before image. This happened because the (don't care)
bytes in the NULLed fields would change once the row was stored
in the storage engine (from zero to the default value). This
would make bulk memory comparison (using memcmp) to fail.
  
We fix this by taking a preventing measure and avoiding memcmp
for tables that contain nullable fields. Therefore, we protect
the slave search routine from engines that return arbitrary
values for don't care bytes (in the nulled fields). Instead, the
slave thread will only check null_bits and those fields that are
not set to NULL when comparing the before image against the
storage engine row.

Fixed the author and the copyright.

Issue:
------
Due to prefix match, database like 'k' was matching with 'ka' and events of 'ka' we getting displayed for 'show event' of 'k'.

Resolution:
-----------
Scan for listing of events in a schema is made to be done on exact match of database (schema) name instead of just prefix.

The condition cursor-protocol => ps-protocol was done at "current setting" level"
Moved it to "set by command line" level
