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 5.0, and is the first of a set of
       patches to remove LGPL from all trees.

prepared statements with cursor protocol).

The problem was a bug in Materialized-cursor implementation.
Materialized_cursor::open() called send_result_metadata()
with items pointing to already closed table.

The fix is to send metadata when the table is still open.

NOTE: this is a "partial" fix: metadata are different with
and without --cursor-protocol, but that's a different large
problem, one indication of which is reported as Bug 24176.

Bug#11766500 - 59624: FUNCS_1 SUITE TESTS FAILING WITH RESULT DIFFERENCE WHEN RUN USING EMBEDDED MODE
Updating result file for embedded mode tests due to recent changes

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.

Fixed the author and the copyright.

  configuration wizard to fail

Made the fields mysql.user.plugin and mysql.user.authentication_string
nullable to conform with some older clients doing inserts instead of 
using the commands.

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

Regression from bug#11766232.
m_last_part could be set beyond the last partition.
Fixed by only setting it if within the limit.
Also added check in print_error.

Fixed test suite failures when the auth plugin is not compiled in.

Added the cleanup code.
Extended mysql_client_test to take --plugin-dir and --default_auth.
Added a C test case.

                with no .cnf or .ini extension.

Fix for this bug was pushed as part of Bug#11765482.

Problem: the test had not been updated after BUG#49978 was pushed
Fix: add 'set $rpl_only_running_threads= 1' to the end of the test
and update the result file.
Also, use include/assert.inc for an assertion (instead of relying
on result file comparison).
Also, move 'set @@global.slave_net_timeout' forwards, to get rid
of a warning.

Currently, rpl_semi_sync is failing in PB due to the warning message:

  "Slave SQL: slave SQL thread is being stopped in the middle of "
  "applying of a group having updated a non-transaction table; "
  "waiting for the group completion ..."

The problem started happening after the fix for BUG#11762407 what was
automatically suppressing some warning messages.

To fix the current issue, we suppress the aforementioned warning message
and exploit the opportunity to make the sentence clearer.

Automerge: mysql-5.1 --> mysql-5.5 

      
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.
