r2944 has reference to mysql_bin_log.is_open(), which is new in InnoDB.
Add two new entries and remove one duplicate in mysqld.def & 
mysqld_x64.def.

Revert our temporary fix for "Bug#40360 Binlog related errors with binlog off"
(r2935, r2936) and deploy MySQL's one, but put the function
mysql_bin_log_is_engaged() inside mysql_addons.cc instead of in mysql's log.cc
and use a different name for it so there is no collision when MySQL adds this
function in log.cc.

  1. We add a vector of locks to trx_t. This array contains the autoinc
  locks granted to a transaction. There is one per table.

  2. We enforce releasing of these locks in the reverse order from the
  one in which they are acquired. The assumption is that since the
  AUTOINC locks are statement level locks. Nested statements introduced
  by triggers are stacked it should hold.

There was some cleanup done to the vector code too by adding const and
some new functions. Rename dict_table_t::auto_inc_lock to autoinc_lock.

Add ChangeLog entry for Bug#40360 Binlog related errors with binlog off

Followup to r2935: add the Windows Delay Loader stuff for the MySQL
variable that we are accessing. If someday we have another solution for
Bug#40360 Binlog related errors with binlog off
then this should also be reverted.

Fix "Bug#40360 Binlog related errors with binlog off" in InnoDB code in order
to have a Bug#40360-free InnoDB Plugin 1.0.2.

The fix does check whether binary logging is enabled in MySQL by accessing the
opt_bin_log global variable that is defined in sql/mysqld.cc.

In case MySQL does develop another solution to this via Bug#40360 then we can
revert this patch (except the mysql-tests).

The windows-plugin part of this fix will be committed as a separate commit to
ease eventual merge into branches/5.1 [note from the future: the separate
commit went into r2936].

  branches/5.1: dtype_get_sql_null_size(): return the correct storage
  size of a SQL NULL column. (Bug #40369)

  When MySQL Bug #20877 was fixed in r834, this function was
  accidentally modified to return 0 or 1. Apparently, the only impact of
  this bug is that fixed-length columns cannot be updated in-place from
  or to SQL NULL, even in ROW_FORMAT=REDUNDANT.  After this fix,
  fixed-length columns in ROW_FORMAT=REDUNDANT will have a constant
  storage size as they should, no matter if NULL or non-NULL.  The bug
  caused fixed-length NULL columns to occupy 1 byte.

ChangeLog:

add entry for the Windows plugin.

Spotted by Sunny.

when INNODB_DYNAMIC_PLUGIN is specified.

The changes are:

CMakeLists.txt: add project ha_innodb for dynamic plugin on Windows.
ha_innodb depends on project mysqld.

ha_innodb.def: a new file with standard exports for a dynamic plugin.

Two new files will be added:
 * sql/mysqld.def:	.def file for 32-bit compiler
 * sql/mysqld_x64.def:	.def file for x64 compiler

It is also required to apply a patch to the MySQL source tree. The 
patch is described in win-plugin/README:

win-plugin/win-plugin.diff - a patch to be applied to MySQL source
tree. When applied, the following files will be modified:
 * CMakeLists.txt:	add INNODB_DYNAMIC_PLUGIN and _USE_32BIT_TIME_T
 * sql/CMakeLists.txt:	add mysqld.def or mysqld_x64.def for mysqld
 * win/configure.js:	add INNODB_DYNAMIC_PLUGIN
 * win/build-vs71.bat:	provide an option to specify CMAKE_BUILD_TYPE
 * win/build-vs8.bat:	provide an option to specify CMAKE_BUILD_TYPE
 * win/build-vs8_x64.bat: provide an option to specify CMAKE_BUILD_TYPE

on Windows, which includes:

 * Load mysqld.map and insert all symbol/address pairs into hash for
   quick access
 * Resolves all external data variables. The delayloading mechanism
   in MSVC does not support automatic imports of data variables.
   A workaround is to explicitly handle the data import using the delay
   loader during the initialization of the plugin.
 * Resolves all external functions during run-time, by implementing
   the delayed loading helper function delayLoadHelper2, which is
   called by run-time as well as HrLoadAllImportsForDll. 

The delay loader reuses the hash implementation in InnoDB. The normal
hash_create (in hash0hash.c) creates hash tables in buffer pool. But
the delay loader is invoked before the engine is initialized, and 
buffer pools are not ready yet. Instead, the delay loader has its own
implementation of hash_create() and hash_table_free(), called
wdl_hash_create() and wdl_hash_table_free().

This patch should be used with other two patches in order to build
a dynamically linked plugin on Windows:
 * patch for tmpfile functions (r2886)
 * patch for "build" files (to be committed)
 
The list of file changed:

handler/handler0vars.h: new file, defines a list of external data
variables (no external functions).

handler/win_delay_loader.cc: new file, the implementation of the delay
loader for Windows plugin.

handler/ha_innodb.cc: add a header file, and changes for copying the
system variables.

handler/handler0alter.cc: add a header file

handler/i_s.cc: add a header file

The changed file:

White space cleanup in ChangeLog

cannot be restored, do not complain if the tablespace does not exist.
This fixes Issue #88.

ibuf_get_volume_buffered(): Declare with static linkage.
This function is private to ibuf0ibuf.c.

btr_cur_pessimistic_delete(): Use the cached result of
btr_cur_get_index(cursor).

trx_sys_file_format_max_upgrade(): Rename from
trx_sys_file_format_max_update().  Improve the documentation.  Add a
const qualifier to the parameter "name".  Replace the parameter
"flags" with "format_id", because this function should deal with file
format identifiers, not with table flags.

trx_sys_file_format_max_write(), trx_sys_file_format_max_set(): Add a
const qualifier to the parameter "name".

ha_innodb.cc: Correct the spelling in some comments: "side effect".
Remove redundant prototypes for some static callback functions.

innodb_file_format_name_update(), innodb_file_format_check_update():
Correct the function signature.  Use appropriate pointer type conversions.

MYSQL_SYSVAR_STR(file_format), MYSQL_SYSVAR_STR(file_format_check):
Remove the type conversions from the callback function pointers.  When
the function signatures match, no type conversion is needed.  The type
conversions would only prevent compilation warnings for any mismatch.
