Improve the generated instructions for multiplying 32 bits by 32 bits
and squaring 32 bits with 64 bit results.
Minimize loads in montgomery reduction, mul and sqr.
Pull conditional subtract into montgomery reduction assembly code.
Added unrolled square and multiply
Define WOLFSSL_SP_LARGE_CODE to use the unrolled versions.
* make ASN1_OBJECT arg const in OBJ_obj2txt
* add ERR_LIB values to openssl/ssl.h
* add missing alert type definitions in openssl/ssl.h
* add definition for X509_CHECK_FLAG_NO_PARTIAL_WILDCARDS, no support
* define value for X509_CHECK_FLAG_ALWAYS_CHECK_SUBJECT
* use correct CRYPTO_THREADID arg type for wolfSSL_THREADID_set_callback callback
* add handshake type defines for compat layer message callback types
* define ASN1_R_HEADER_TOO_LONG for compatibility builds
* use correct return type for wolfSSL_THREADID_set_callback, remove Qt code no longer needed
* add DIST_POINT compatibility functions
* switch X509_LU_* from enum to define, prevent compiler type warnings
* refactoring, adding in comments, and formating
* refactoring and a memory leak fix
* cast return value for g++ warning
* refactor wolfSSL_sk_DIST_POINT_pop_free and remove NULL assign after free
* fix get next DIST_POINT node for free function

Also, fixes for the things they caught such as:
- ssl->arrays->preMasterSecret is pre-allocated so copy into it instead of
moving ownership of buffer.
- server does not need to save the public key.
- in TLSX_KeyShare_Parse() don't call TLSX_KeyShare_Use() because its done in
TLSX_PopulateExtensions().
- in TLSX_KeyShare_Use(), the server generates the ciphertext while the client
generates the public key.
- in TLSX_PopulateExtensions(), prevent client from calling TLSX_KeyShare_Use()
because its already been done.
- Support longer curve/group names.
* Remove NTRU and OQS
* Keep the DTLS serialization format backwards compatible.
* Remove n from mygetopt_long() call.
* Fix over-zealous deletion.
* Resolve problems found by @SparkiDev
smallstack refactors for wolfcrypt/src/rsa.c:wc_CheckProbablePrime_ex() and wolfcrypt/src/pwdbased.c:wc_PKCS12_PBKDF_ex();
add WARN_UNUSED_RESULT macro to types.h;
text format cleanup;
fix internal.c:LowResTimer() implementation.
refactor tls13.c:TimeNowInMilliseconds() for kernel 4.9 and 3.16 compat.
use ktime_get_coarse_real_ts64() only for kernel 5.x+. in kernel 4.x, use its older form, current_kernel_time64(), and in 3.x, use getnstimeofday().
linuxkm/module_hooks.c: fix wolfssl_init() pie code to be compatible with kernel 4.4-;
fix allocate_wolfcrypt_irq_fpu_states() return codes to all be wolfcrypt codes, and in calling code, pass up that code (suggested by dgarske peer review).
configure.ac: fix ed25519/sha512 dependency test to not misfire when ENABLED_32BIT;
wolfssl/wolfcrypt/curve{25519,448}.h: fix redundant typedefs of curve{25519,448}_key (fixes -Wpedantic warnings);
configure.ac: fix for "ISO C forbids an empty translation unit [-Werror=pedantic]", re wolfcrypt/src/sp_c{32,64}.c;
configure.ac: fixes for --enable-32bit versus pedantic "ISO C forbids an empty translation unit", including explicit exclusion of 32bit-incompatible algorithms from enable-all and enable-all-crypto sets;
tests/api.c: fixes for a couple inadequately gated SHA2 dependencies;
tests/api.c:test_wolfSSL_set_alpn_protos(): fix prototype missing (void);
wolfcrypt/src/misc.c and wolfssl/wolfcrypt/misc.h: fix ForceZero() definition and NO_INLINE prototype to not counterfactually constify the mem ptr, to avoid -Wmaybe-uninitialized from gcc11;
wolfcrypt/src/des3.c: drop obsolete register qualifier from declaration in DesSetKey(), for c++17 compatibility;
src/ssl.c:wolfSSL_BN_mod_word(): fix cast of arg2 to mp_mod_d().
add build-time support for module signing using native Linux facility;
add support for alternative licenses using WOLFSSL_LICENSE macro;
improve load-time kernel log messages;
add support for sp-math-all asm/AVX2 acceleration;
add error-checking and return in SAVE_VECTOR_REGISTERS();
implement support for x86 accelerated crypto from interrupt handlers, gated on WOLFSSL_LINUXKM_SIMD_X86_IRQ_ALLOWED:
* wolfcrypt_irq_fpu_states
* am_in_hard_interrupt_handler()
* allocate_wolfcrypt_irq_fpu_states()
* free_wolfcrypt_irq_fpu_states()
* save_vector_registers_x86()
* restore_vector_registers_x86()
add WOLFSSL_LINUXKM_SIMD, WOLFSSL_LINUXKM_SIMD_X86, and WOLFSSL_LINUXKM_SIMD_ARM macros for more readable gating.
