wolfssl/wolfcrypt/aes.h: add key_C_fallback[] to struct Aes, and remove comment that "AESNI needs key first, rounds 2nd, not sure why yet" now that AES_128_Key_Expansion_AESNI no longer writes rounds after the expanded key.
wolfcrypt/src/aes.c:
* add _AESNI or _aesni suffixes/infixes to AESNI implementations that were missing them: AES_CBC_encrypt(), AES_CBC_decrypt_by*(), AES_ECB_encrypt(), AES_*_Key_Expansion(), AES_set_encrypt_key(), AES_set_decrypt_key(), AES_GCM_encrypt(), AES_GCM_decrypt(), AES_XTS_encrypt(), and AES_XTS_decrypt().
* move key size check from to start of wc_AesSetKeyLocal().
* refactor pure-C AES setkey and cipher implementations to use aes->key_C_fallback when defined(WC_AES_C_DYNAMIC_FALLBACK).
* refactor wc_AesSetKeyLocal() to set up both AESNI and pure-C expanded keys when defined(WC_AES_C_DYNAMIC_FALLBACK).
* refactor all (haveAESNI && aes->use_aesni) conditions to just (aes->use_aesni).
* add macros VECTOR_REGISTERS_PUSH and VECTOR_REGISTERS_POP, which do nothing but push a brace level when !defined(WC_AES_C_DYNAMIC_FALLBACK), but when defined(WC_AES_C_DYNAMIC_FALLBACK), they call SAVE_VECTOR_REGISTERS2() and on failure, temporarily clear aes->use_aesni and restore at _POP().
* refactor all invocations of SAVE_VECTOR_REGISTERS() and RESTORE_VECTOR_REGISTERS() to VECTOR_REGISTERS_PUSH and VECTOR_REGISTERS_POP, except in wc_AesSetKeyLocal(), wc_AesXtsEncrypt(), and wc_AesXtsDecrypt(), which are refactored to use SAVE_VECTOR_REGISTERS2(), with graceful failure concealment if defined(WC_AES_C_DYNAMIC_FALLBACK).
* orthogonalize cleanup code in wc_AesCbcEncrypt(), wc_AesCcmEncrypt() and wc_AesCcmDecrypt().
* streamline fallthrough software definitions of wc_AesEncryptDirect() and wc_AesDecryptDirect(), and remove special-casing for defined(WOLFSSL_LINUXKM)&&defined(WOLFSSL_AESNI).
wolfcrypt/src/aes_asm.{S,asm}:
* remove errant "movl $10, 240(%rsi)" from AES_128_Key_Expansion_AESNI.
* add _AESNI suffixes/infixes to implementations that needed them.
wolfcrypt/src/{aes_gcm_asm.{S,asm},aes_xts_asm.S}: regenerate from revisions in scripts#357 -- adds _aesni suffixes to implementations that were missing them.
wolfssl/wolfcrypt/types.h: remove DEBUG_VECTOR_REGISTER_ACCESS macros, and add dummy fallthrough definitions for SAVE_VECTOR_REGISTERS2 and WC_DEBUG_SET_VECTOR_REGISTERS_RETVAL.
wolfssl/wolfcrypt/memory.h: adopt DEBUG_VECTOR_REGISTER_ACCESS code from types.h, and add definitions for WC_DEBUG_VECTOR_REGISTERS_RETVAL_INITVAL and WC_DEBUG_SET_VECTOR_REGISTERS_RETVAL.
linuxkm/linuxkm_wc_port.h: add arch-specific macro definitions for SAVE_VECTOR_REGISTERS2().
wolfcrypt/benchmark/benchmark.c: add missing gates around calls to RESTORE_VECTOR_REGISTERS().
configure.ac:
* cover various interdependencies in enable-all/enable-all-crypto, for better behavior in combination with --disable-aesgcm, --disable-ecc, --disable-ocsp, --disable-hmac, --disable-chacha, --disable-ed25519, and --disable-ed448.
* inhibit aesgcm_stream in enable-all/enable-all-crypto when ENABLED_LINUXKM_DEFAULTS, because it is currently incompatible with WC_AES_C_DYNAMIC_FALLBACK.
* add -DWC_AES_C_DYNAMIC_FALLBACK when ENABLED_LINUXKM_DEFAULTS.
* add 3 new interdependency checks: "ECCSI requires ECC.", "SAKKE requires ECC.", "WOLFSSH requires HMAC."
wolfcrypt/src/asn.c: tweak gating to accommodate defined(NO_RSA) && !defined(HAVE_ECC).
wolfcrypt/src/evp.c: tweak gating to accommodate defined(NO_HMAC).
wolfcrypt/src/logging.c: remove DEBUG_VECTOR_REGISTER_ACCESS code (moved to memory.c).
wolfcrypt/src/memory.c: change #include of settings.h to types.h; adopt DEBUG_VECTOR_REGISTER_ACCESS code from logging.c; add implementation of SAVE_VECTOR_REGISTERS2_fuzzer().
wolfcrypt/src/pwdbased.c: add explanatory #error scrypt requires HMAC.
wolfcrypt/test/test.c:
* add DEBUG_VECTOR_REGISTER_ACCESS clauses to aes_xts_128_test(), aesecb_test(), aesctr_test(), aes_test() CBC section, aes256_test() CBC section, and aesgcm_default_test_helper()
* remove duplicate wc_AesEcbDecrypt() in aesecb_test().
* add gating for pbkdf2_test().
* fix cleanup code in dsa_test().
* fix gating in pkcs7authenveloped_run_vectors() to accommodate !defined(HAVE_AESGCM).
* fix gating in cryptocb_test() to accommodate defined(NO_HMAC).
wolfssl/wolfcrypt/cryptocb.h: remove gates around "pk" sub-struct of struct wc_CryptoInfo -- wc_CryptoInfo.pk.type (an int) is used unconditionally when --enable-debug, and is used with DH.
wolfssl/wolfcrypt/error-crypt.h: fix whitespace.
linuxkm/linuxkm_wc_port.h: activate SAVE/RESTORE_VECTOR_REGISTERS() whenever defined(WOLFSSL_LINUXKM_USE_SAVE_VECTOR_REGISTERS) for benchmark.c support, independent of vector crypto features;
fix and optimize various alignment issues with stack and heap allocations;
fix macro definitions for XMALLOC/XREALLOC/XFREE to correctly use kvmalloc and friends when defined(HAVE_KVMALLOC), and to use wolfSSL_Malloc() and friends when defined(WOLFSSL_TRACK_MEMORY);
purge stale LINUXKM_SIMD_IRQ code.
linuxkm: when -DWOLFCRYPT_ONLY, don't include ssl.h in module_exports.c.template and module_hooks.c, and fix gating to work right with that;
wolfssl/wolfcrypt/types.h: add support for a WOLFSSL_XFREE_NO_NULLNESS_CHECK gate (used in cppcheck analysis).
