of InnoDB buffer pool initialization to the error log

GCOV builds were broken after the patch for Bug#57933
which added add -Wdeclaration-after-statement to gcc builds.

This patch fixes:
stacktrace.c:328: warning: ISO C90 forbids mixed
declarations and code

No test case added.

Bug#58041 : Moved rpl_binlog_row to daily. Run just main suite for ps_row and embedded per push. Other suites run daily

sporadically.

The cause of the sporadic time out was a leaking protection
against the global read lock, taken by the RENAME statement,
and not released in case of an error occurred during RENAME.
The leaking protection counter would lead to the value of
protect_against_global_read never dropping to 0.
Consequently FLUSH TABLES in all connections, including the
one that leaked the protection, could not proceed.
 
The fix is to ensure that all branchesin RENAME code properly
release GRL protection.

  Note that g++ refuses this flag.

Improve the diagnostics of buffer pool accesses for B-trees,
so that the file names and line numbers of the real calls are shown
instead of the line of the buf_page_get() call in btr_block_get().

btr_page_get(): Replaced with a macro.

btr_block_get_func(): Renamed from btr_block_get(). Add file, line.

btr_block_get(): A macro that passes the __FILE__, __LINE__ to
btr_block_get_func().

dict_truncate_index_tree(): Replace a btr_page_get() call
with btr_block_get(), since we are only latching the page, not accessing it.

and make some function comments more accurate.

This patch doesn't get rid of the need to acquire the dict_sys->mutex but
reduces the need to keep the mutex locked for the duration of the query
to fsp_get_available_space_in_free_extents() from ha_innobase::info().
 
This is a port of revno:3548 from the builtin to the plugin.

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.

columns again

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.

            by a function and column

The bugreport reveals two different bugs about grouping
on a function:

1) grouping by the TIME_TO_SEC function result caused
   a server crash or wrong results and
2) grouping by the function returning a blob caused
   an unexpected "Duplicate entry" error and wrong
   result.

Details for the 1st bug:

TIME_TO_SEC() returns NULL if its argument is invalid (empty
string for example). Thus its nullability depends not only
on the nullability of its arguments but also on their values.
Fixed by (overoptimistically) setting TIME_TO_SEC() to be
nullable despite the nullability of its arguments.

Details for the 2nd bug:

The server is unable to create indices on blobs without
explicit blob key part length. However, this fact was
ignored for blob function result fields of GROUP BY
intermediate tables.
Fixed by disabling GROUP BY index creation for blob
function result fields like regular blob fields.

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.

This is for InnoDB Plugin.

  Simplified cases where a select was used to compare variable against ''

Rows events were applied wrongly on the temporary table with the same name.
But rows events are generated only for base tables. As temporary
table's data never be binlogged on row mode. Normally, base table of the
same name cannot be updated if a temporary table has the same name.
But there are two cases which can generate rows events on 
the base table of same name.
      
Case1: 'CREATE TABLE ... SELECT' statement.
In mixed format, it will generate rows events if it is unsafe.
      
Case2: Drop a transactional temporary table in a transaction
       (happens only on 5.5+).
BEGIN;
DROP TEMPORARY TABLE t1;       # t1 is a InnoDB table
INSERT INTO t1 VALUES(rand()); # t1 is a MyISAM table
COMMIT;
'DROP TEMPORARY TABLE' will be put in the transaction cache and
binlogged after the rows events generated by the 'INSERT' statement.
      
After this patch, slave opens only base table when applying a rows event.
