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.
       (See Bug# 11840513 for details)



include/my_compare.h:
  Mostly code moved in from my_handler

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.

mysql-test/r/events_bugs.result:
  modified expected file with the expected results.
mysql-test/t/events_bugs.test:
  added a test case to reproduce the scenario.
sql/event_db_repository.cc:
  Scan for schema name is made to be done on exact db name match.

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.
