Problem was that test just takes too long time in slow I/O and triggers
testcase timeout. Reduced the number of operations and inserts to make
test shorter.
Analysis; Problem is that InnoDB does not have support for generating
CURRENT_TIMESTAMP or constant default.
Fix: Add additional check if column has changed from NULL -> NOT NULL
and column default has changed. If this is is first column definition
whose SQL type is TIMESTAMP and it is defined as NOT NULL and
it has either constant default or function default we must use
"Copy" method for alter table.
Introduce a new dummy INFORMATION_SCHEMA.CHANGED_PAGE_BITMAPS table to XtraDB
with reset_table callback to allow FLUSH NO_WRITE_TO_BINLOG CHANGED_PAGE_BITMAPS
to be called from innobackupex.
Problem:
If we add a referential integrity constraint with a duplicate
name, an error occurs. The foreign key object would not have
been added to the dictionary cache. In the error path, there
is an attempt to remove this foreign key object. Since this
object is not there, the search returns a NULL result.
De-referencing the null object results in this crash.
Solution:
If the search to the foreign key object failed, then don't
attempt to access it.

Problem was that information schema tables innodb_tablespaces_encryption and
innodb_tablespaces_scrubbing where missing required check is InnoDB enabled
or not.
With changes:
* update tests to pass (new encryption/encryption_key_id syntax).
* not merged the code that makes engine aware of the encryption mode
(CRYPT_SCHEME_1_CBC, CRYPT_SCHEME_1_CTR, storing it on disk, etc),
because now the encryption plugin is handling it.
* compression+encryption did not work in either branch before the
merge - and it does not work after the merge. it might be more
broken after the merge though - some of that code was not merged.
* page checksumming code was not moved (moving of page checksumming
from fil_space_encrypt() to fil_space_decrypt was not merged).
* restored deleted lines in buf_page_get_frame(), otherwise
innodb_scrub test failed.
if XA PREPARE transactions hold explicit locks.
innobase_shutdown_for_mysql(): Call trx_sys_close() before lock_sys_close()
(and dict_close()) so that trx_free_prepared() will see all locks intact.

The test case was missing --source include/wait_for_binlog_checkpoint.inc.
So it could occasionally fail if the checkpoint managed to occur just at the
right point in time between fetching the two binlog positions to compare.
Step 3:
-- Make encrytion_algorithm changeable by SUPER
-- Remove AES_ECB method from encryption_algorithms
-- Support AES method change by storing used method on InnoDB/XtraDB objects
-- Store used AES method to crypt_data as different crypt types
-- Store used AES method to redo/undo logs and checkpoint
-- Store used AES method on every encrypted page after key_version
-- Add test
Analysis: MySQL table definition contains also virtual columns. Similarly,
index fielnr references MySQL table fields. However, InnoDB table definition
does not contain virtual columns. Therefore, when matching MySQL key fieldnr
we need to use actual column name to find out referenced InnoDB dictionary
column name.
Fix: Add new function to match MySQL index key columns to InnoDB dictionary.
