      Description

      Since upgrading my OS to a version which ships mariadb built against openssl 3.0.2, I am seeing server crashes in both my_md5() and my_aes()

      status: process terminated by SIGSEGV (Segmentation Fault), pid=25463 uid=70
      > $C
      fffffaffee718aa0 libcrypto.so.3`evp_cipher_init_internal+0x3d()
      fffffaffee718ac0 libcrypto.so.3`EVP_CipherInit_ex+0xf()
      fffffaffee718ad0 MyCTX::init+0x1d()
      fffffaffee718dd0 my_aes_crypt+0x64()
      fffffaffee718ed0 Item_aes_crypt::val_str+0x110()
      

      status: process terminated by SIGSEGV (Segmentation Fault), pid=14380 uid=70
      > $C
      fffffaffed89efe0 libcrypto.so.3`EVP_MD_free+5()
      fffffaffed89f000 libcrypto.so.3`EVP_MD_CTX_reset+0x2c()
      fffffaffed89f080 my_md5+0x46()
      fffffaffed89f0d0 Item_func_md5::val_str_ascii+0x53()
      fffffaffed89f110 Item_func::val_str_from_val_str_ascii+0x85()
      

      Changing the code to use the new openssl APIs with EVP_CIPHER/MD_CTX_new/free() resolves the problem for me, but that doesn't fix the plugin API.
