# commit f163d8b5af9185de80d24b4dd13951dd64872aa6
# Author: Rainer Jung <rjung@apache.org>
# Date:   Sun Feb 7 14:40:46 2016 +0000
# 
#     Add support for OpenSSL 1.1.0:
#     - Switch configure test for OpenSSL libcrypto
#       from BN_init() to BN_new().
#       - BN_init() is gone in OpenSSL 1.1.0.
#         BN_new() exists at least since 0.9.8.
#     - use OPENSSL_malloc_init() instead of
#       CRYPTO_malloc_init
#     - make cipherCtx a pointer. Type EVP_CIPHER_CTX
#       is now opaque.
#       - use EVP_CIPHER_CTX_new() in init() functions
#         if initialised flag is not set (and set flag)
#       - use EVP_CIPHER_CTX_free() in cleanup function
#     - Improve reuse cleanup
#       - call EVP_CIPHER_CTX_reset() resp.
#         EVP_CIPHER_CTX_cleanup() in finish functions
#       - call EVP_CIPHER_CTX_reset() resp.
#         EVP_CIPHER_CTX_cleanup() when Update fails
#     Backport of r1728958 and r1728963 from trunk.
#     
#
