* OPENSSL_COMPATIBLE_DEFAULTS:

* should make porting to new projects easier.
* WOLFSSL_CHECK_ALERT_ON_ERR:
* Check for alerts during the handshake in the event of an error.
* NO_SESSION_CACHE_REF:
* wolfSSL_get_session on a client will return a reference to the internal
* ClientCache by default for backwards compatibility. This define will
* make wolfSSL_get_session return a reference to ssl->session. The returned
* pointer will be freed with the related WOLFSSL object.
* SESSION_CACHE_DYNAMIC_MEM:
* Dynamically allocate sessions for the session cache from the heap, as
* opposed to the default which allocates from the stack. Allocates
* memory only when a session is added to the cache, frees memory after the
* session is no longer being used. Recommended for memory-constrained
* systems.
* WOLFSSL_SYS_CA_CERTS
* Enables ability to load system CA certs from the OS via
* wolfSSL_CTX_load_system_CA_certs.
