[8.3-stable] Resolves naming conflicts between variable names and c++ identifiers-"new"

[smfc99]

gcc 7.3.1 std17 编译 tongsuo 会产生如下的错误：

ERROR: /root/workspace/CubeNet/src/crypto/BUILD:1:1: C++ compilation of rule '//src/crypto:cube_crypto' failed (Exit 1) gcc failed: error executing command /opt/rh/devtoolset-7/root/usr/bin/gcc -Wextra -Wno-unknown-pragmas -Wno-unused-parameter -Wno-deprecated-declarations -Wno-implicit-fallthrough -Wno-unused-private-field -Wignored-qualifiers ...

原因是：tongsuo 是 c 语言实现的，结构体 EVP_KDF_METHOD 里面的变量命名为 new 会和 c++ 中的标识符 new 产生命名冲突。
/* struct evp_kdf_impl_st is defined by the implementation */
typedef struct evp_kdf_impl_st EVP_KDF_IMPL;
typedef struct {
int type;
EVP_KDF_IMPL *(*new) (void);
void (*free) (EVP_KDF_IMPL *impl);
void (*reset) (EVP_KDF_IMPL *impl);
int (*ctrl) (EVP_KDF_IMPL *impl, int cmd, va_list args);
int (*ctrl_str) (EVP_KDF_IMPL *impl, const char *type, const char *value);
size_t (*size) (EVP_KDF_IMPL *impl);
int (*derive) (EVP_KDF_IMPL *impl, unsigned char *key, size_t keylen);
} EVP_KDF_METHOD;
