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.

No conflicts.

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.

Added back the specific warning number.

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.

 (aka BUG#11766883)
  - fix review comments
  - Rewrite last usage of handler::get_tablespace_name to use
    table->s->tablespace directly
  - Remove(revert) the addition of default implementation for
    handler::get_tablespace_name
  - Add comments describing the new TABLE_SHARE members default_storage_media
    and tablespace
  - Fix usage of incorrect mask for column_format bits, i.e COLUMN_FORMAT_MASK

Removing the test case from mysql-5.5 list of disabled
test cases for the binlog suite. Actually, the test does
not exist in mysql-5.5, thus this is just a clean up.

Original patch did not remove the test case from the list
of disabled test cases. Removing it now!

  
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.

Initialized correctly the have_innodb variable so that when the plugin is not initialized it
stays "disabled" instead of "yes".
Test suite added.

Didn't build on Solaris.
