93efbc390d MDEV-22214 mariadbd.exe calls function mysqld.exe, and crashes
Stop linking plugins to the server executable on Windows.
Instead, extract whole server functionality into a large DLL, called
server.dll. Link both plugins, and small server "stub" exe to it.

This eliminates plugin dependency on the name of the server executable.
It also reduces the size of the packages (since tiny mysqld.exe
and mariadbd.exe are now both linked to one big DLL)

Also, simplify the functionality of exporing all symbols from selected
static libraries. Rely on WINDOWS_EXPORT_ALL_SYMBOLS, rather than old
self-backed solution.

fix compile error

replace GetProcAddress(GetModuleHandle(NULL), "variable_name")
for server exported data with actual variable names.

Runtime loading was never required,was error prone
, since symbols could be missing at runtime, and now it actually failed,
because we do not export symbols from executable anymore, but from a shared
library

This did require a MYSQL_PLUGIN_IMPORT decoration for the plugin,
but made the code more straightforward, and avoids missing symbols at
runtime (as mentioned before).

The audit plugin is still doing some dynamic loading, as it aims to work
cross-version. Now it won't work cross-version on Windows, as it already
uses some symbols that are *not* dynamically loaded, e.g fn_format
and those symbols now exported from server.dll , when earlier they were
exported by mysqld.exe

Windows, fixes for storage engine plugin loading
after various rebranding stuff

Create server.dll containing functionality of the whole server
make mariadbd.exe/mysqld.exe a stub that is only  calling mysqld_main()

fix build

5e4b657dd4 MDEV-18531 : Use WolfSSL instead of YaSSL as "bundled" SSL/encryption library
- Add new submodule for WolfSSL
- Build and use wolfssl and wolfcrypt instead of yassl/taocrypt
- Use HAVE_WOLFSSL instead of HAVE_YASSL
- Increase MY_AES_CTX_SIZE, to avoid compile time asserts in my_crypt.cc
(sizeof(EVP_CIPHER_CTX) is larger on WolfSSL)

4aaa38d26e Enusure that my_global.h is included first
- Added sql/mariadb.h file that should be included first by files in sql
  directory, if sql_plugin.h is not used (sql_plugin.h adds SHOW variables
  that must be done before my_global.h is included)
- Removed a lot of include my_global.h from include files
- Removed include's of some files that my_global.h automatically includes
- Removed duplicated include's of my_sys.h
- Replaced include my_config.h with my_global.h

7bf409593e MDEV-11660 Make encryption plugins "pure"
Do not exporting mysqld entry points directly.
This is needed for mariabackup, to load encryption plugins on Windows.

All plugins are "pure" by default. To mark plugin "impure"
it should use RECOMPILE_FOR_EMBEDDED or STORAGE_ENGINE keyword.
