Linux: added a log when miner is started as root to discourage doing so.

cpuminer-opt-23.5

New version numbering drops the leading 3, the major version will now be the calendar year, the minor version identifies planned releases during the year.

BETA: 64 bit ARM support

• ARM 64 bit CPUs are now supported with source code for Linux. Windows is not supported.

• NEON, AES & SHA2 are supported.

• This the first public release and is early Beta quality.

• Some algorithms do not work on ARM or work at reduced performance.
  See wiki for details: https://github.com/JayDDee/cpuminer-opt/wiki/Support-for-AArch64.

• CPU archtecture and OS detection and logging now support ARM features.

• New 2way parallel hash for ARM also helps x86_64 CPUs without AVX2 on supported algorithms.

• Enhanced startup feature logs to support ARM.

• Removed startup logs for incompatible CPU/SW architectures.

• Added CPU architecture & OS type to RPC user agent string.

• Added share reject controls, a warning log is displayed at 10% reject rate, the miner exits with an error log at 50%.

• Removed argon2 algorithm.

• New CLI option "--bell" adds an ASCII bell code in the output string of error, warning, & rejected share logs. The option is disabled by default.

cpuminer-opt-3.23.3

Windows binaries updated with libcrypto-1_1-x64.dll from openssl v1.1.1w. No other changes.

#400: Removed excessive thread restarts when mining solo.
Fixed build_msys2.sh for gcc-13 by removing unsupported option "--param=evrp-mode=legacy" from CFLAGS.
Added CPUID detection and reporting of CPUs and SW builds supporting SHA512 extension.
Added prototype of sha-512 using SHA512 intrinsics, untested.
Other improvements and code cleanup.

cpuminer-opt-3.23.2

sha256dt, sha256t & sha256d +10% with SHA, small improvement with AVX2.
Other small improvements and code cleanup.

#349: Fix sha256t low difficulty shares and low effective hash rate.
Faster sha256dt: AVX512 +7%, SHA +200%, AVX2 +5%.
Faster blakecoin & vanilla: AVX2 +30%, AVX512 +110%.
Other small improvements and code cleanup.

Fix a false start if stratum doesn't immediately send a new job after connecting.
Tweak diagonal shuffle in Blake2b & Blake256 1-way SIMD to reduce latency.
CPUID support for AVX10.
Initial changes to AVX2 targeted code in preparation for AVX10.
Code cleanup and miscellaneous small improvements.
