* refine explanatory comments in settings.h re WOLFSSL_USE_OPTIONS_H, WOLFSSL_NO_OPTIONS_H, and WOLFSSL_CUSTOM_CONFIG.
* add safety catch to options.h/options.h.in to inhibit inclusion if defined(WOLFSSL_NO_OPTIONS_H).
* for good measure, add explicit check for WOLFSSL_NO_OPTIONS_H to wolfcrypt/benchmark/benchmark.c and wolfcrypt/test/test.c.
configure.ac: add OPENSSL_EXTRA to --enable-wolfsentry.
linuxkm/linuxkm_wc_port.h, linuxkm/module_hooks.c, wolfssl/ssl.h: accommodate backward dependencies for wolfSSL_X509_NAME_add_entry_by_NID, wolfSSL_X509_NAME_free, and wolfSSL_X509_NAME_new_ex.

wolfssl/wolfcrypt/settings.h: adopt setup for WOLFSSL_SP_NO_UMAAL from wolfssl/wolfcrypt/sp_int.h now that it's used by wolfcrypt/src/port/arm/thumb2-poly1305-asm.S.
tests/api.c: add error_test() adapted from wolfcrypt/test/test.c, checking all error strings for expected presence/absence and length, called from existing test_wolfSSL_ERR_strings().
wolfssl/ssl.h, wolfssl/error-ssl.h, and wolfssl/wolfcrypt/error-crypt.h:
* move several negative error return codes from ssl.h to error-ssl.h,
* renumber them to conform to existing sequence, and
* include error-ssl.h from ssl.h;
* add special-case WOLFSSL_DEBUG_TRACE_ERROR_CODES macros for WOLFSSL_FAILURE;
* add missing WOLFSSL_API attribute to wc_backtrace_render().

* crypto test&benchmark (20),
* TLS lib (179),
* examples (122),
* linuxkm (3),
* tests/api.c (2272).
also, additional backward-compatibility measures around cp and clean recipe in linuxkm/Makefile.
also, in sp_int.c, tweak DECL_DYN_SP_INT_ARRAY() to use an explicit XMEMSET() to clear n[], to avoid unshimmable implicit memset() from gcc on aarch64.
wolfcrypt/test/test.c and linuxkm/lkcapi_glue.c: update AES-XTS streaming calls to use struct XtsAesStreamData;
linuxkm/lkcapi_glue.c: add handling for CONFIG_CRYPTO_MANAGER*.
wolfcrypt/test/test.c:
* add WOLFSSL_AESXTS_STREAM testing to the LARGE_XTS_SZ exercise in aes_xts_128_test().
* add the LARGE_XTS_SZ exercise to aes_xts_256_test().
* add aes_xts_192_test().
* fix -Werror=frame-larger-than=2048 in ed25519_test().
linuxkm/lkcapi_glue.c: typographic cleanups, and failsafe error return constructs when skcipher_walk_virt() returns zero walk.nbytes.
wolfcrypt/src/aes.c: additional comments and inline documentation.
.github/workflows/openvpn.yml: disable test on master branch.
* fix WC_LINUXKM_ROUND_UP_P_OF_2() to not round up values that are already powers of 2, nor values larger than 8192.
linuxkm/lkcapi_glue.c:
* fix gating on km_AesSetKeyCommon().
* small stack refactors of Aes objects in self-test routines.
* change kmalloc/free to malloc/free in self-test routines.
* fix error-path "return"s to "goto exit"s in self-test routines.
* fix memory leak around large_input in aes_xts_128_test().
wolfcrypt/benchmark/benchmark.c:
* smallstack refactors in bench_chacha() and bench_chacha20_poly1305_aead().
* add error handling in bench_chacha().
wolfcrypt/src/chacha20_poly1305.c: smallstack refactor for wc_ChaCha20Poly1305_Encrypt() and wc_ChaCha20Poly1305_Decrypt().
* fix overallocation in WC_DECLARE_ARRAY() macro in the !WOLFSSL_SMALL_STACK path.
* rename WC_INIT_ARRAY() to WC_ALLOC_ARRAY() for clarity (it doesn't initialize any memory).
* rename WC_DECLARE_ARRAY_DYNAMIC_DEC(), WC_DECLARE_ARRAY_DYNAMIC_EXE(), and WC_FREE_ARRAY_DYNAMIC() to WC_DECLARE_HEAP_ARRAY(), WC_ALLOC_HEAP_ARRAY(), and WC_FREE_HEAP_ARRAY(), respectively, also for clarity, and refactor out the duplicate definitions.
* add WC_ALLOC_VAR(), and move the XMALLOC() in smallstack WC_DECLARE_VAR() into it. smallstack WC_DECLARE_VAR() now initializes the pointer to NULL, like smallstack WC_DECLARE_ARRAY(), assuring all pointers are valid upon shortcircuit to cleanup for a failed allocation (see WC_ALLOC_DO_ON_FAILURE below).
* add a new hook "WC_ALLOC_DO_ON_FAILURE" in WC_ALLOC_VAR(), WC_ALLOC_ARRAY(), and WC_DECLARE_ARRAY_DYNAMIC_EXE(), which is invoked when an allocation fails. by default the hook is defined to WC_DO_NOTHING.
* add basic safety to WC_*_HEAP_ARRAY() by recording/detecting allocation state via idx##VAR_NAME.
* add macros WC_ARRAY_OK() and WC_HEAP_ARRAY_OK() to test if allocation succeeded.
* add macros WC_CALLOC_ARRAY() and WC_CALLOC_HEAP_ARRAY() which zero the objects.
* add macro WC_CALLOC_VAR() which zeros the object.

src/tls.c tests/api.c wolfcrypt/test/test.c: update WC_DECLARE_VAR()s with now-required matching WC_ALLOC_VAR()s.
wolfcrypt/benchmark/benchmark.c:
* no functional changes in default error-free behavior.
* add definition of WC_ALLOC_DO_ON_FAILURE() that prints error message, sets ret, and does goto exit.
* add BENCH_NTIMES and BENCH_AGREETIMES overrideeable macros, to allow fast sanitizer runs and slow high-precision runs.
* smallstack refactor of all declarations of stack arrays of the form foo[BENCH_MAX_PENDING], using WC_DECLARE_ARRAY() (35 in all).
* additional smallstack refactors, using WC_DECLARE_VAR(), for bench_aesxts(), bench_ed448KeyGen(), bench_eccsi*(), and bench_sakke*().
* fixes for various unhandled error conditions around malloc failures.
wolfcrypt/test/test.c: opportunistically constify several (42) static constants, moving them to the readonly data segment.
linuxkm/Makefile: if ENABLED_LINUXKM_BENCHMARKS, add wolfcrypt/benchmark/benchmark.o to WOLFSSL_OBJ_FILES.
linuxkm/Kbuild: enable FPU for benchmark.o, and remove enablement for module_hooks.o.
linuxkm/module_hooks.c: remove inline include of benchmark.c.
configure.ac: move enable_aesgcm_stream=yes clauses in enable-all and enable-all-crypto to the main section, from the !ENABLED_LINUXKM_DEFAULTS section, and in ENABLED_LINUXKM_LKCAPI_REGISTER setup, remove the !ENABLED_AESNI from the condition for forcing on ENABLED_AESGCM_STREAM.
linuxkm/lkcapi_glue.c:
* remove all special-casing for AES-GCM with AESNI.
* add support for a LINUXKM_LKCAPI_PRIORITY_ALLOW_MASKING macro.
wolfssl/wolfcrypt/memory.h: add missing definition of SAVE_VECTOR_REGISTERS2() when DEBUG_VECTOR_REGISTER_ACCESS_FUZZING && !DEBUG_VECTOR_REGISTER_ACCESS.
wolfcrypt/src/memory.c:
* define SAVE_VECTOR_REGISTERS2_fuzzer() if DEBUG_VECTOR_REGISTER_ACCESS_FUZZING, regardless of DEBUG_VECTOR_REGISTER_ACCESS.
* add a DEBUG_VECTOR_REGISTER_ACCESS clause to the !HAVE_THREAD_LS version of SAVE_VECTOR_REGISTERS2_fuzzer().
wolfcrypt/test/test.c: remove several errant wc_AesFree()s in aes256_test().
* add support for DEBUG_LINUXKM_FORTIFY_OVERLAY to allow KASAN analysis of the overlay without actually enabling CONFIG_FORTIFY_SOURCE (which is buggy in combination with KASAN).
* make SAVE_VECTOR_REGISTERS2 definition conditional on !defined(SAVE_VECTOR_REGISTERS2).
wolfssl/wolfcrypt/memory.h: fix the DEBUG_VECTOR_REGISTER_ACCESS definition for SAVE_VECTOR_REGISTERS to properly omit the on-success bookkeeping code even if the supplied fail_clause doesn't return.
wolfcrypt/src/rsa.c: in wc_MakeRsaKey() primality loop, invoke RESTORE_VECTOR_REGISTERS() SAVE_VECTOR_REGISTERS() to prevent lengthy kernel lockups.
wolfcrypt/src/dh.c: in wc_DhGenerateParams() primality loop, invoke RESTORE_VECTOR_REGISTERS() SAVE_VECTOR_REGISTERS() to prevent lengthy kernel lockups.
wolfcrypt/src/{curve25519.c,dh.c,dsa.c,ecc.c,eccsi.c,rsa.c,sakke.c,sp_int.c}: when WOLFSSL_LINUXKM, force {SAVE,RESTORE}_VECTOR_REGISTERS() to WC_DO_NOTHING if settings gate out applicable asm.
