  Cover four special cases of WL#4166 with tests:
  - when the query cache is disabled at the time of prepared statement
  reprepare
  - when long data parameters are used
  - when character_set_connection != character_set_client, and a parameter
  conversion takes place
  - when parameter data is out of acceptable range, e.g. year 10000 is

The default name of the PID file was constructed, as documented, 
based on the hostname.  This name was subsequently used as the
base for the general log file name.   If the name of the PID
file was overridden in the configuration, and no explicit name
was set for the general log file, the path location for the
PID file was used also for the general log file.
                  
A new variable, 'default_logfile_name', has been introduced.  This name
is constructed based on the hostname, and is then used to
construct both the PID file and the general log file.
                  
The general log file will now, unless explicitly set, be
located in the server data directory (as documentated in
the server docs)

The problem was that a COMMENT longer than 64 characters
caused CREATE PROCEDURE to fail.

This patch fixed the problem by changing the COMMENT field in 
mysql.proc from char(64) to text. The corresponding ROUTINE_COMMENT
field in INFORMATION_SCHEMA.ROUTINES is also changed from
varchar(64) to longtext.

mysql_system_tables.sql and mysql_system_tables_fix.sql updated.
Test case added to sp.test and affected result-files updated.

case than in corr index".

Server was unable to find existing or explicitly created supporting
index for foreign key if corresponding statement clause used field
names in case different than one used in key specification and created
yet another supporting index.
In cases when name of constraint (and thus name of generated index)
was the same as name of existing/explicitly created index this led
to duplicate key name error.

The problem was that unlike all other code Key_part_spec::operator==()
compared field names in case sensitive fashion. As result routines
responsible for getting rid of redundant generated supporting indexes
for foreign key were not working properly for versions of field names
using different cases.

  Fix for Bug#40128: drop-no_root fails under windows in 6.0-rpl.
  
  The problem was that directories with no permission (000) files
  are deleted differently on UNIX and on Windows.
  
  On UNIX, 000-permission file is deleted perfectly, but other files
  are left in the directory.
  
  On Windows, 000-permission file is not deleted, but other files
  are deleted.
  
  Also, the fix needed a change in mysqltest.c: 'chmod' directive
  should return a positive error code (in order to be handled).
  It's decided to return a constant '1' for all error codes
  just to be OS-independent.

           InnoDB specified.
            
NO_ENGINE_SUBSTITUTION added to TRADITIONAL sql mode to prevent
silent conversions from InnoDB to MyISAM in that sql mode.

A number of test case results files updated to reflect this change.
Test added to sql_mode.test that checks that TRADITIONAL really 
includes NO_ENGINE_SUBSTITUION.

storing and restoring information about foreign keys in the .FRM files and
properly displaying it in SHOW CREATE TABLE output and I_S tables.

The idea of this patch is to change type of Key_part_spec::field_name and
Key::name to LEX_STRING in order to avoid extra strlen() calls during
semantic analysis and statement execution, particularly, in code to be
implemented on the 2nd milestone of WL#148.

Note that since we are not using LEX_STRING everywhere yet (e.g. in
Create_field and KEY) and we want to limit scope of our changes we
have to do strlen() in places where we create Key and Key_part_spec
instances from objects using plain (char*) for strings. These calls
will go away during the process of further (char*) -> LEX_STRING
refactoring.

We have introduced these changes in 6.0 and backported them to 5.5
tree to make people aware of these changes as early as possible and
to simplify merges with mysql-fk and mysql-6.1-fk trees.

No test case is needed since this patch does not introduce any
user visible changes.

           "have_profiling"

1) Renamed have_community_features server system variable to
have_profiling.
2) Removed eable-community-features configure option and
ENABLE_COMMUNITY_FEATURES macro.
3) Removed COMMUNITY_SERVER macro and replaced its usage by 
ENABLED_PROFILING.

Only --enable-profiling is now needed to enable profiling.
It was the only existing "community feature", so there was
no need for both configure options.

Using --enable-community-features will give a warning message
since it no longer exists.

To-number conversion warnings work differenly with CHAR 
and VARCHAR sp variables.

The patch provides ER_TRUNCATED_WRONG_VALUE warning messages
for conversion of VARCHAR to numberic values, in line with
messages provided for CHAR conversions. Conversions are
checked for success, and the message is emitted in case
failure.
                                                
The tests are amended to accept the added warning messages,
and explicit conversion of ON/OFF values is added for
statements checking system variables. In test
rpl.rpl_switch_stm_row_mixed checking for warnings is
temporarily disabled for one statement, as this generates
warning messages for strings that vary between executions.

An ALTER TABLE statement which added a column and added
a non-partial index on it failed with:
            
"ERROR 1089 (HY000): Incorrect sub part key; the used
key part isn't a string, the used length is longer than
the key part, or the storage engine doesn't support unique
sub keys"
            
In a check introduced to fix an earlier bug (no. 26794),
to allow for indices on spatial type columns, the
test expression was flawed (a logical OR was used instead
of a logical AND), which led to this regression.
            
The code in question does a sanity check on the key, and
the flawed code mistakenly classified any index created
in the way specified above as a partial index.  Since
many data types does not allow partial indices, the
statement would fail.

           given an already connected MYSQL handle

mysql_real_connect() did not check whether the MYSQL connection
handler was already connected and connected again even if so. 
Now a CR_ALREADY_CONNECTED error is returned.

           says * for global allowed

The current behaviour of 'GRANT *' was changed as a part of the fix
for Bug#19022, Bug#17199 and Bug#18444. To avoid regression, we keep
the current behavior and update the documentation. 
Test case added to grant.test.

lowercasing table name".

In lower_case_table_names > 0 mode some queries to I_S left entries
with incorrect key in table definition cache. This wasted memory and
caused some of the further queries to I_S to produce stale results
in cases when table definition was changed by a DDL statement.
Also in combination with similar problem in CREATE TABLE (which also
has peeked into table definition cache using non-normalized key) this
issue led to to spurious ER_TABLE_EXISTS_ERROR errors when one tried
to create a table with the same name as a previously existing but
dropped table (assuming that table name contained characters in upper
case).

This problem occured due to fact that fill_schema_table_from_frm()
was not properly normalizing (lowercasing) database and table names
which it used for lookups in table definition cache.

This fix adds proper normalization to this function. It also solves
similar problem in CREATE TABLE's code by ensuring that it uses
properly normalized version of table name when it peeks into table
definition cache instead of non-normalized one.
