- SSL_CTX_set_cert_cb
- SSL_certs_clear
- SSL_add0_chain_cert ssl_cert_add0_chain_cert
- SSL_add1_chain_cert ssl_cert_add1_chain_cert

- SSL_set_client_CA_list
# Other Changes
- Ignore gdbinit
- Add api.c tests for new API
- Add `WOLFSSL_X509_STORE* x509_store_pt` to `WOLFSSL`
- Add macro to select the `WOLFSSL` specific store when available and the associated `WOLFSSL_CTX` store otherwise. Calls to `ssl->ctx->cm` and `ssl->ctx->x509_store*` were replaced by macros.
- NO-OP when setting existing store
- Add reference counter to `WOLFSSL_X509_STORE`
- Cleanup MD5 redundant declarations
- WOLFSSL_ERROR may map to nothing so make assignment outside of it
- refMutex fields are excluded with SINGLE_THREADED macro
- Chain cert refactor
- Make `wolfSSL_add0_chain_cert` and `wolfSSL_add1_chain_cert` not affect the context associated with the SSL object
- `wolfSSL_CTX_add1_chain_cert` now updates the `ctx->certChain` on success and stores the cert in `ctx->x509Chain` for later free'ing
- Add doxygen documentation for wc_GetPkcs8TraditionalOffset, wc_CreatePKCS8Key,
wc_EncryptPKCS8Key, and wc_DecryptPKCS8Key.
- Add a new API function, wc_CreateEncryptedPKCS8Key, which handles both
creation of an unencrypted PKCS#8 key and the subsequent encrypting of said key.
This is a wrapper around TraditionalEnc, which does the same thing. This may
become a first-class function at some point (i.e. not a wrapper). TraditionalEnc
is left as is since it is used in the wild.
- Added a unit test which exercises wc_CreateEncryptedPKCS8Key and
wc_DecryptPKCS8Key. Testing wc_CreateEncryptedPKCS8Key inherently also tests
TraditionalEnc, wc_CreatePKCS8Key, and wc_EncryptPKCS8Key.
- Modified wc_EncryptPKCS8Key to be able to return the required output buffer
size via LENGTH_ONLY_E idiom.
- Added parameter checking to wc_EncryptPKCS8Key and wc_DecryptPKCS8Key.
* Added TLS v1.3 sniffer support using static ephemeral key.
* Add support for using a static ephemeral DH and ECC keys with TLS v1.3 using `WOLFSSL_STATIC_EPHEMERAL`.
* Adds new API's `wolfSSL_CTX_set_ephemeral_key` and `wolfSSL_set_ephemeral_key`.
* Expanded TLS extension support in sniffer.
* Refactor of the handshake hashing code.
* Added parameter checking to the TLS v1.3 key derivations (protects use of "DoTls13Finished" if handshake resources have been free'd).
* Added support for loading DH keys via `wc_DhImportKeyPair` and `wc_DhExportKeyPair`, enabled with `WOLFSSL_DH_EXTRA`.
* Added sniffer documentation `sslSniffer/README.md`.
