Starting at 5.1.38, MySQL server exports symbols needed
for dynamic plugin on Windows. There is no need for
Windows specific loading. Also, the CMake files are
simplified in 5.1.38.
When WITH_INNOBASE_STORAGE_ENGINE is specified during
configuration (win\configure.js), InnoDB is built as
a static library. Otherwise, a dynamic InnoDB will be
built (ha_innodb.dll).
CMakeLists.txt requires minor changes in order to work
with MySQL prior to 5.1.38. The changes will be in a
separate patch.
This patch addresses Mantis issue#286.
All are non-functional changes:
- should check for long (not int), spotted by Sunny
- comment out the project definition, avoiding to generate another
.sln file.

Mapping the atomic operations to Windows Interlocked functions:
os_compare_and_swap_* to InterlockedCompareExchange(64)
os_atomic_increment_* to InterlockedExchangeAdd(64)
os_atomic_test_and_set_byte to InterlockedExchange
In this patch, the legacy code under UNIV_CAN_USE_X86_ASSEMBLER is
removed all together, and add HAVE_WINDOWS_ATOMICS and
INNODB_RW_LOCKS_USE_ATOMICS to CMakeLists.txt
This is to address mantis issue#194.

To make zlib and strings dynamically linked; mysqld will export
additional functions required by InnoDB.
Since the symbols will be resolved dynamically during runtime,
wdl_load_mapfile() is no longer able to make any function calls
to ones in mysqld. As the result, strtoull() (from strings.lib)
is replaced with _strtoui64().

CMakeLists.txt is completely rewritten with enhancements:
- Print out useful information, such as
system name, directory, generator used,
win64, Microsoft compiler, etc.
- Remove one workaround for mysqld.lib location.
User does not need to specify a build type
when invoking MSVC generator.

The dynamic plugin on Windows used to be built with MYSQL_SERVER
compile flag, while it is not the case for other platforms.
r3797 assumed MYSQL_SERVER was not defined for dynamic plugin,
which introduced the engine crash during dropping a database.
during run-time.
Implement wrapper functions in the plugin. The plugin will get the
function entries from mysqld.exe during the init, and invoke the
corresponding functions (in mysqld.exe). The list of functions are:
_db_pargs_
_db_doprnt_
_db_enter_
_db_return_
_db_dump_

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
overrun of the buffer being freed with 64-bit Microsoft Visual C++.
The changed file:
CMakeLists.txt: Removing Win64 compiler optimizations for all
innodb/mem/* files.
Add CMake-generated files and directories to svn:ignore. This patch
is from Calvin Sun, who couldn't commit it properly on Windows.
Do "svn propset svn:eol-style native" on every text file, to fix
line format problems on Windows.
