Subject: [PATCH] BUGFIX: Fixed segmentation fault on CyaSSL_BIO_free().

In CyaSSL_BIO_new_socket() bio->mem is never initialized. This will cause freeing of unallocated memory in CyaSSL_BIO_free:

if (bio->mem)
  XFREE(bio->mem, 0, DYNAMIC_TYPE_OPENSSL);

since bio->mem is not NULL, resulting in a crash.
