Clean up includes single return point from every function, consistent formatting function block comment and tests added.
ssl_api_rw.c: Cleanup; 6 helpers extracted from write_dup/shutdown; fixed a SendBuffered corner case that returned 0 instead of an error.
ssl_api_ext.c: Cleanup; extracted wolfssl_ticket_key_cb_process, wolfssl_rehandshake_prepare.
ssl_api_hs.c: Cleanup + de-indent; 9 helpers extracted, incl. shared wolfssl_handshake_flush/_done between connect and accept (~100 duplicated lines removed). wolfSSL_connect/accept left multi-exit.
ssl_api_cert.c: Cleanup of newer functions at end of file; extracted PushPeerCertToChain; fixed a double free in CreatePeerCertChain; fixed 5 wrong @param names.
ssl_api_crl_ocsp.c: Full cleanup of all 49 functions; wolfSSL_OCSP_parse_url rewritten; fixed a URL with no host returning success with the rest of the URL as the host; added IPv6 literal support; fixed 4 wrong WOLFSSL_ENTER names.
ssl.c: Moved the x509GetIssuerFromCM forward declaration here for clarity.
