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

Bug#11766500 - 59624: FUNCS_1 SUITE TESTS FAILING WITH RESULT DIFFERENCE WHEN RUN USING EMBEDDED MODE
      
Updating result files

      
There is a race between two threads: user thread and the dump
thread. The former sets a debug instruction that makes the latter wait
before processing an Xid event. There can be cases that the dump
thread has not yet processed the previous Xid event, causing it to
wait one Xid event too soon, thus causing sync_slave_with_master never
to resume.
      
We fix this by moving the instructions that set the debug variable
after calling sync_slave_with_master.

This will cause affected tests to skip if CrashReporter would popup

The problem was that server didn't check resulting size of prepared
statement argument which was set using mysql_send_long_data() API.
By calling mysql_send_long_data() several times it was possible
to create overly big string and thus force server to allocate
memory for it. There was no way to limit this allocation.

The solution is to add check for size of result string against
value of max_long_data_size start-up parameter. When intermediate
string exceeds max_long_data_size value an appropriate error message
is emitted.

We can't use existing max_allowed_packet parameter for this purpose
since its value is limited by 1GB and therefore using it as a limit
for data set through mysql_send_long_data() API would have been an
incompatible change. Newly introduced max_long_data_size parameter
gets value from max_allowed_packet parameter unless its value is
specified explicitly. This new parameter is marked as deprecated
and will be eventually replaced by max_allowed_packet parameter.
Value of max_long_data_size parameter can be set only at server
startup.

Add a missing DBUG_RETURN function test_if_number().

Issue:
      SSL_CIPHER set to a specific CIPHER name was not getting picked up by SHOW STATUS Command.

Solution:
      If specific cipher name is specified, avoid overwriting of Cipher List with default Cipher names.
