* tweaks to xmss_test() for compatibility with WOLFSSL_NO_MALLOC && NO_WOLFSSL_MEMORY;
* fixes for return codes in dilithium_test().
wolfssl/wolfcrypt/dilithium.h: add !WC_NO_CONSTRUCTORS gate around wc_dilithium_new() and wc_dilithium_delete() prototypes, to match gating in implementation.
* fixes for readability-implicit-bool-conversion in wolfSSL_Atomic_Ptr_CompareExchange().
* refactor initRefCount as a wolfSSL_Atomic_Int, unless !WOLFSSL_ATOMIC_OPS, for thread safety.
* add WC_RNG_BANK_STATIC to WC_RNG_BANK_SUPPORT, supporting WOLFSSL_NO_MALLOC;
* in random_bank_test(), fix gate around _NO_VECTOR_OPS sha256.sha_method test (WOLFSSL_SMALL_STACK_CACHE, and USE_INTEL_SPEEDUP not WC_HAVE_VECTOR_SPEEDUPS);
* in definition of struct wc_rng_bank_inst, accommodate WOLFSSL_NO_ATOMICS builds;
wolfssl/wolfcrypt/random.h: in definition of struct WC_RNG, add gate to avoid empty union in !HAVE_HASHDRBG configs.
wolfcrypt/src/rng_bank.c:
* add wc_local_rng_bank_checkout_for_bankref, wc_BankRef_Release(), wc_rng_bank_new(), and wc_rng_bank_free();
* in wc_rng_bank_checkin(), take a struct wc_rng_bank_inst **rng_inst and NULL it before return;
* in wc_rng_bank_init(), add a devId arg, and handle devId in wc_rng_bank_inst_reinit();
* add WC_RNG_BANK_INST_LOCK_* and use them in wc_rng_bank_checkout() and wc_rng_bank_checkin();
* fix order of operations in wc_rng_bank_checkout() re DISABLE_VECTOR_REGISTERS();
wolfcrypt/src/random.c:
* refactor per-instance salting for wc_rng_bank_inst: remove changes in Hash_df(), Hash_DRBG_Instantiate(), and _InitRng(), and in wc_rng_bank_init() and wc_rng_bank_inst_reinit(), use wc_InitRngNonce_ex() and pass the wc_rng_bank_inst pointer as the nonce;
* simplify the WC_RNG_BANK_SUPPORT variant of wc_RNG_GenerateBlock() -- delegate to wc_local_rng_bank_checkout_for_bankref() and remove supplementary error checking;
* in wc_FreeRng(), call wc_BankRef_Release() when WC_DRBG_BANKREF, and in wc_BankRef_Release(), fix refcount flub (not wolfSSL_RefFree, rather wolfSSL_RefDec);
* streamline the WOLFSSL_LINUXKM wc_GenerateSeed();
wolfcrypt/test/test.c: add random_bank_test();
linuxkm/lkcapi_sha_glue.c: use WC_RNG_BANK_INST_TO_RNG() opportunistically;
configure.ac: add --enable-amdrdseed as a synonym for --enable-amdrand;
linuxkm/linuxkm_wc_port.h: when LINUXKM_LKCAPI_REGISTER_HASH_DRBG_DEFAULT, don't include get_random_bytes() in struct wolfssl_linuxkm_pie_redirect_table;
add various comments for clarity.
* refactor to eliminate recursion in wc_RNG_GenerateBlock();
* refactor enum wc_rng_bank_flags as word32 and macros;
* fix -Wconversions, -Wunused, and stray EINVAL in wc_rng_bank_init();
* make struct wc_rng_bank_inst a top-level definition for C++ compat;
* fix several bugprone-macro-parentheses.
* add WC_DRBG_BANKREF status code;
* add `struct wc_rng_bank *bankref` to struct WC_RNG, and move status slot out from HAVE_HASHDRBG gate;
* add WC_DRBG_MAX_SALT_SZ, and add saltSz and salt slots to struct DRBG_internal;
* add salt handling to Hash_df(), Hash_DRBG_Instantiate(), and _InitRng();
* add types:
* enum wc_rng_bank_flags
* struct wc_rng_bank
* add implementations:
* wc_rng_bank_init()
* wc_rng_bank_set_affinity_handlers()
* wc_rng_bank_fini()
* wc_rng_bank_checkout()
* wc_rng_bank_checkin()
* wc_rng_bank_inst_reinit()
* wc_rng_bank_seed()
* wc_rng_bank_reseed()
* wc_InitRng_BankRef()
* wc_rng_new_bankref()
* WC_RNG_BANK_INST_TO_RNG()
* in wc_RNG_GenerateBlock() and wc_FreeRng(), add WC_RNG_BANK_SUPPORT sections;
wolfcrypt/src/random.c: in WC_VERBOSE_RNG messages, add "ERROR: " prefixes to text to assure pickup by autotesting. also fixed line lengths.
