pre-locking list caused by triggers).

The thing is that CREATE TRIGGER / DROP TRIGGER may actually
change pre-locking list of (some) stored routines.

The SP-cache does not detect such changes. Thus if sp_head-instance
is cached in SP-cache, subsequent executions of the cached
sp_head will use inaccurate pre-locking list.

The patch is to invalidate SP-cache on CREATE TRIGGER / DROP TRIGGER.

improved the result file readability.

Before this fix, two performance schema unit tests crashed on windows.

The problem was a missing initialization to PFS_atomics,
which caused the crash only for platform not compiled with native atomics.

This fix adds the missing initialization in the unit tests.
No production code was changed, this is a unit test bug only.

MAP 'REPAIR TABLE' TO RECREATE +ANALYZE FOR ENGINES NOT
SUPPORTING NATIVE REPAIR

Executing 'mysqlcheck --check-upgrade --auto-repair ...' will first issue
'CHECK TABLE FOR UPGRADE' for all tables in the database in order to check if the
tables are compatible with the current version of MySQL. Any tables that are
found incompatible are then upgraded using 'REPAIR TABLE'.

The problem was that some engines (e.g. InnoDB) do not support 'REPAIR TABLE'.
This caused any such tables to be left incompatible. As a result such tables were
not properly fixed by the mysql_upgrade tool.

This patch fixes the problem by first changing 'CHECK TABLE FOR UPGRADE' to return
a different error message if the engine does not support REPAIR. Instead of
"Table upgrade required. Please do "REPAIR TABLE ..." it will report
"Table rebuild required. Please do "ALTER TABLE ... FORCE ..."

Second, the patch changes mysqlcheck to do 'ALTER TABLE ... FORCE' instead of
'REPAIR TABLE' in these cases.

This patch also fixes 'ALTER TABLE ... FORCE' to actually rebuild the table.
This change should be reflected in the documentation. Before this patch,
'ALTER TABLE ... FORCE' was unused (See Bug#11746162)

Test case added to mysqlcheck.test

              NON-PRIMARY UNIQUE INDEX USING INNODB

This patch adds the HA_INPLACE_ADD_UNIQUE_INDEX_NO_WRITE
capability flag to InnoDB, indicating that concurrent reads
can be allowed while non-primary unique indexes are created.

This is an follow-up to Bug #11751388 which enabled concurrent
reads when creating non-primary non-unique indexes.

Test case added to innodb_mysql_sync.test.

FLUSH TABLES under FLUSH TABLES <list> WITH READ LOCK leads 
to assert failure.

This assert was triggered if a statement tried up upgrade a metadata
lock with an active FLUSH TABLE <list> WITH READ LOCK. The assert 
checks that the connection already holds a global intention exclusive
metadata lock. However, FLUSH TABLE <list> WITH READ LOCK does not
acquire this lock in order to be compatible with FLUSH TABLES WITH
READ LOCK. Therefore any metadata lock upgrade caused the assert to
be triggered.

This patch fixes the problem by preventing metadata lock upgrade
if the connection has an active FLUSH TABLE <list> WITH READ LOCK.
ER_TABLE_NOT_LOCKED_FOR_WRITE will instead be reported to the client.

Test case added to flush.test.

  Refactoring (thanks to Guilhem for the idea):

  Item_string::print() was hard to understand because of the different
  QT_ constants: in "query_type==QT_x", QT_x is explicitely included
  but the other two QT_ are implicitely excluded. The combinations
  with '||' and '&&' make this even harder.
  - logic is now more "explicit" by changing QT_ constants to a bitmap of flags:
    QT_ORDINARY: no change,
    QT_IS -> QT_TO_SYSTEM_CHARSET | QT_WITHOUT_INTRODUCERS,
    QT_EXPLAIN -> QT_TO_SYSTEM_CHARSET
    (QT_EXPLAIN was introduced in the first version of the Bug#57341 patch)
  - Item_string::print() is rewritten using those flags

  Bugfix itself:

  When QT_TO_SYSTEM_CHARSET is used alone (with no QT_WITHOUT_INTRODUCERS),
  we print string literals as follows:

  - display introducers if they were in the original query
  - print ASCII characters as is
  - print non-ASCII characters using hex-escape
  Note: as "EXPLAIN" output is only for human readability purposes
  and does not need to be a pasrable SQL, so using hex-escape is Ok.
  ErrConvString class perfectly suites for hex escaping purposes.

               CLIENT CONFIGURATION.

At startup, MySQL server/client programs do not read
configuration file pointed by MYSQL_HOME environment
variable.

This happened as, this environment variable was
handled by a different variable (DEFAULT_HOME_ENV)
in the code, which was ne'er initialized.

Fixed by changing it to MYSQL_HOME.

In this bug, args[0] in an Item_func_find_in_set stored an 
Item_func_weekday that was constant. In 
Item_func_find_in_set::fix_length_and_dec(), args[0]->val_str() 
was called. Later, when Item_func_find_in_set::val_int() was 
called, args[0]->null_value was checked. However, the 
Item_func_weekday in args[0] had now been replaced with an 
Item_cache. No val_*() calls had been made to this Item_cache,
thus null_value was incorrectly 'true', resulting in missing 
rows in the result set.

enum_value gets a value in fix_length_and_dec() iff args[0]
is both constant and non-null. It is therefore unnecessary 
to check the null_value of args[0] in val_int().

An alternative fix would be to call args[0]->val_int() inside 
Item_func_find_in_set::val_int(). This would ensure
args[0]->null_value was set correctly (always false in this case), 
but that would have to be done for every record this const value 
is checked against.
