removed and replaced by the comprehensive innodb-create-options.test.
It uses the rules listed in the comments at the top of that test.
  
This patch introduces these differences from previous behavior;
1)  KEY_BLOCK_SIZE=0 is allowed by Innodb in both strict and non-strict mode
with no errors or warnings. It was previously used by the server to set 
KEY_BLOCK_SIZE to undefined.  (Bug#56628)
2)  An explicit valid non-DEFAULT ROW_FORMAT always takes priority over a
valid KEY_BLOCK_SIZE. (bug#56632)
3)  Automatic use of COMPRESSED row format is only done if the ROW_FORMAT
is DEFAULT or unspecified.
4)  ROW_FORMAT=FIXED is prevented in strict mode.

This patch also includes various formatting changes for consistency with
InnoDB coding standards.

This is follow-up to Bug #54358. Not all occurrences of the bug were fixed.
We need to check all calls to btr_copy_externally_stored_field_prefix_low()
and do the right thing when the pointer to the off-page column is null
(full of zero bytes).

It turns out that only the call to btr_copy_externally_stored_field_prefix()
in row_sel_sec_rec_is_for_blob() needs to be changed.

For fetching complete off-page columns rather than prefixes, the function
btr_rec_copy_externally_stored_field() already checks if the pointer
is null (all-zero).  Two of its callers (row_merge_copy_blobs() and
row_sel_fetch_columns()) are never executed as READ COMMITTED and can
rightfully assert that the fetch succeeded.  The third caller,
row_sel_store_mysql_rec(), already does the right thing.

The calls in row_upd_ext_fetch() and trx_undo_page_fetch_ext() must
expect that the off-page column exists. Update and rollback are
locking operations, never READ UNCOMMITTED.

btr_estimate_n_rows_in_range_on_level(): Always do mtr_commit(),
so that the page will not remain pinned indefinitely.

On Windows, the parameter for number of bytes passed into WriteFile()
and ReadFile() is DWORD. Casting is needed to silence the warning on
64-bit Windows.

Also, adding several asserts to ensure the variable for number of bytes
is no more than 32 bits, even on 64-bit Windows.

buf_pool_init(): Replace ut_ad(n_instances < MAX_BUFFER_POOLS)
with ut_ad(n_instances <= MAX_BUFFER_POOLS).
(Spotted by Michael Izioumtchenko.)
Add ut_ad(n_instances > 0).

buf_page_t: Remove the buf_pool pointer. Add buf_pool_index:6 next to
buf_fix_count:19 (it was buf_fix_count:25). This will limit the number
of concurrent transactions to somewhere around 524,288.

buf_pool_index(buf_pool): A new function to determine the index of a
buffer pool in buf_pool_ptr[].

buf_pool_ptr: Make this a dynamically allocated array instead of an
array of pointers. Allocate the array in buf_pool_init() and free in
buf_pool_free().

buf_pool_free_instance(): No longer free the buf_pool object, as it is
allocated from a big array.

buf_pool_from_bpage(), buf_pool_from_block(): Move the definitions to
the beginning of the files, because some compilers have (had) problems
with forward definitions of inline functions. Calculate the buffer
pool from buf_pool_index.

buf_pool_from_array(): Add debug assertions for input validation.

CMakeLists.txt: Remove the checks for mysql_storage_engine.cmake
and MYSQL_VERSION_ID.

ha_innodb.cc, ha_innodb.h: Remove the checks for MYSQL_VERSION_ID.

  Fix handling of update_undo_logs at trx commit. Previously, when
  rseg->update_undo_list grows beyond 500 the update_undo_logs were
  marked with state TRX_UNDO_TO_FREE which should have been
  TRX_UNDO_TO_PURGE.
  In 5.5 we don't need the heuristic as we support multiple rollback
  segments.

Bug#57720 - Windows Vista and possibly Windows 7 can return ERROR_TIMEOUT instead of WAIT_TIMEOUT from calls to SleepConditionVariableCS() which is used in os0sync.c; os_cond_wait_timeout() where it is mapped to sleep_condition_variable().   

Consider ERROR_TIMEOUT to be a timeout just like WAIT_TIMEOUT.  

In addition, test for EINTR as a possible return value from pthread_cond_timeout() in the posix section of os_cond_wait_timeout(), even though it is not supposed to be returned, but just to be safe.

COM_CHANGE_USER was always handled like an implicit request to change the
client plugin, so that the client can re-use the same code path for both normal 
login and COM_CHANGE_USER. However this doesn't really work well with old 
clients because they don't understand the request to change a client plugin.

Fixed by implementing a special state in the code (and old client issuing 
COM_CHANGE_USER). In this state the server parses the COM_CHANGE_USER 
package and pushes back the password hash, the user name and the database 
to the input stream in the same order that the native password server side plugin 
expects. As a result it replies with an OK/FAIL just like the old server does thus
making the new server compatible with older clients.

No test case added, since it would requre an old client binary. Tested using 
accounts with and without passwords. Tested with a correct and incorrect 
password.

The problem was that the warnings risen by a trigger were not cleared upon
successful completion. The warnings should be cleared if the trigger completes
successfully.

The fix is to skip merging warnings into caller's Warning Info for triggers.
