* Add TLSv1.3 stateful support
Fix internal and external session cache
* session cache fixes
* Refactor
- implement wolfSSL_CTX_flush_sessions
- use wolfSSL_CTX_flush_sessions to make test_wolfSSL_CTX_add_session_ext deterministic
- add dtls to test_wolfSSL_CTX_add_session_ext
- DoClientTicket_ex does not modify ssl object
- only call session remove callback on:
- timeout
- session is being overwritten/removed from the cache
* Session fixes
- restore bogus ID on session duplicate
- don't evict on overwrite
- use memmove instead on memcpy as `ssl->session == session` is possible
- ignore ClientSession parameter in AddSessionToCache on NO_SESSION_CACHE_REF
- use sessionID when altSessionID not present
* Session fixes
- DoClientTicketFinalize: always copy in the ID as teh altSessionID
- don't overwrite ex_data when overwriting cacheSession and cacheSession owns it
* Callback wants to retain a copy
* wolfSSL_GetSessionClient: ssl->ctx->get_sess_cb does not apply here
* test_wolfSSL_CTX_add_session_ext
gate expected results on WOLFSSL_DTLS_NO_HVR_ON_RESUME
* TlsSessionIdIsValid: copy return can't be ignored
* Silence unused parameter
* test_wolfSSL_CTX_add_session_ext: handle async case
* Gate wolfSSL_SSL_CTX_remove_session on NO_SESSION_CACHE
* ssl.c: style fixes
* Add twcase_get_sessionCb_cleanup to free external cache
* Remove hard tab
* Correct build error in wolfSSL_CTX_flush_sessions
* Jenkins fixes:
- altSessionID only available with WOLFSSL_TICKET_HAVE_ID
- slim out psk_sess_free_cb_ctx
* Stateful dtls case has 2 accesses. Stateless just one.
* Add version numbering to hostap logs
* Import internal.h for test_wolfSSL_SESSION_get_ex_new_index
* wolfSSL_SetSession: don't check SslSessionCacheOff for session setting
* wolfSSL_SetSession: fully set expired session for OpenSSL compatibility
* wolfSSL_SetSession: check if setting same object
* AddSession: always populate the session object to allow re-use
* Add logging to wolfSSL_NewSession and wolfSSL_FreeSession
* Always setup session object
* Check if session has been setup before setting it
* Print errors in async test
* Make SetupSession available outside NO_SESSION_CACHE
* Review comments
* Fix ticBuf leak and TlsSessionIdIsValid logic
* Fix unmatched curly brackets
* TlsSessionIdIsValid: always need to check copy var
* TlsResumptionIsValid: set resume to FALSE default
* wolfSSL_SetSession: remove now variable since only used in one place
* Move internalCacheLookupOff into HAVE_EXT_CACHE block

Create a fixed buffer BIO of length 1 and then write one byte into it so
that there is 0 length to write into.
Test cases removed as setting fixed buffer BIO to length 0 allocated 0
length buffer that is sometimes returning NULL.
linuxkm/module_exports.c.template: include wolfssl/wolfcrypt/wolfmath.h, to bring in wc_GetMathInfo() prototype;
src/ssl.c: move "Global pointer to constant BN on" to src/ssl_bn.c; and in wolfSSL_Cleanup(), call the new wolfSSL_BN_free_one() rather than using ad hoc cleanup logic;
src/ssl_bn.c: add bn_one and wolfSSL_BN_free_one();
src/ssl_asn1.c: fix bugprone-macro-parentheses in bufLenOrNull(); refactor wolfSSL_ASN1_TIME_diff() to avoid floating point math; use intermediate tm_year variable in wolfssl_asn1_time_to_tm() to avoid target-specific type conflicts on tm->tm_year; use "FALL_THROUGH", not "/* fall-through */", in wolfSSL_ASN1_TYPE_set (clang-diagnostic-implicit-fallthrough);
wolfcrypt/src/ecc.c: fix identicalInnerCondition in ecc_mul2add();
wolfcrypt/src/integer.c: refactor OPT_CAST()s in mp_grow() to unconditional casts as elsewhere, to mollify a confused cppcheck-all-intmath;
tests/api.c: reformat some overlong lines.
Implementations of ASN.1 APIs reworked.
Added tests.
Added wolfssl_bn_set_neg for ASN.1 code.
Added wolfssl_sk_new_type() and wolfssl_sk_pop_type() to generically
handle creating and popping a stack of elements of a type.
No longer freeing pathlen field of ASN1 OBJECT in
wolfSSL_X509_EXTENSION_free(). This is happening in
wolfSSL_ASN1_OBJECT_free().
Stop wolfSSL_i2d_X509_NAME_canon from double freeing ASN.1 STRING's data
field.
Fixed up GetFormattedTime() to be better code.
Added ASN_CLASS_MASK to mask off the class part of an ASN.1 tag.
NO_ASN_TIME means no implementation to get the current time. Disable
features that won'r work without time.
* Add introspection for math build.
* Raise build error if more than one multi-precision math library used.
* Fix ESP32 to support using any multi-precision math option.
* Refactor math headers to use `wolfmath.h`
* Refactor of the opaque math variable type `MATH_INT_T` used by crypto hardware (QuickAssist, SE050, ESP32 and STM32).
* Cleanups for building with `WOLFCRYPT_ONLY` and `NO_BIG_INT`.
* Stop forcing use of fast math by default for platforms in settings.h. Note: For users that still want to use fast math (tfm.c) they will need to add USE_FAST_MATH to their build settings.
