cpuid.h — added CPUID_ASIMD flag + IS_AARCH64_ASIMD() macro (NEON detection). cpuid.c — added NEON/ASIMD detection fixed FreeBSD/OpenBSD to use HWCAP_* sha256.c — runtime dispatch SHA256-crypto → NEON → software sha512.c — replaced the #error with the same crypto → NEON → software dispatch. chacha.c: add AArch64 runtime fallback to C. poly1305.c: add AArch64 runtime fallback to C. Fixes test_tls.c: don't memcpy into buffer if length is too long. sha256.c: even if data is not NULL, return immediately when length is 0.

Description
cpuid.h — added CPUID_ASIMD flag + IS_AARCH64_ASIMD() macro (NEON detection).
cpuid.c — added NEON/ASIMD detection fixed FreeBSD/OpenBSD to use HWCAP_*
sha256.c — runtime dispatch SHA256-crypto → NEON → software
sha512.c — replaced the #error with the same crypto → NEON → software dispatch.
chacha.c: add AArch64 runtime fallback to C.
poly1305.c: add AArch64 runtime fallback to C.
Fixes
test_tls.c: don't memcpy into buffer if length is too long.
sha256.c: even if data is not NULL, return immediately when length is 0.
Testing
Regression tested Aarch64 platforms.
