This allows us to mark functions as deprecated declarations with OPENSSL_DEPRECATED. We also add an OPENSSL_BEGIN_ALLOW_DEPRECATED and an OPENSSL_END_ALLOW_DEPRECATED for testing use to test deprecated functions. The purpose of this is to allow us to mark things people should not be using as deprecated, and force some inconvenience on the user of such things to notice them (as opposed to a only a warning to not use it that they may not see or read without something tripping them up.) The intent is to still allow use, with some effort, before removing the function, or moving it to libdecrepit. We initially mark X509V3_EXT_add and X509V3_EXT_add_alias as deprecated. Update-Note: We are starting to mark some functions in boringssl as deprecated declarations which will cause the compiler to emit warnings if they are used. The intention is both to prevent accidental use in new code, and to to call attention to call sites in existing code so that the documentation for the deprecated function can be revisted and appropriate action taken.
