v4.3.1-beta

Fixed regression in v4.3.0, miner didn't create cn mining profile with default config example.

#1199 Fixed excessive memory allocation for OpenCL threads with low intensity.
#1212 Fixed low RandomX performance after fast algorithm switching.

#1202 Fixed algorithm verification in donate strategy.

Removed command line option --http-enabled, HTTP API enabled automatically if any other --http-* option provided.

#1177 Fixed compatibility with old AMD drivers.
#1180 Fixed possible duplicated shares after algorithm switching.
Added support for case if not all backend threads successfully started.
Fixed wrong config file permissions after write (only gcc builds on recent Windows 10 affected).

- #268 #270 #271 #273 #274 #1171 Added RandomX support for OpenCL, thanks @SChernykh.
Algorithm cn/wow removed, as no longer alive.

Added per pool option coin with single possible value monero for pools without algorithm negotiation, for upcoming Monero fork.
#1183 Fixed compatibility with systemd.

#1180 Fixed possible duplicated shares after algorithm switching.
Fixed wrong config file permissions after write (only gcc builds on recent Windows 10 affected).

Many RandomX optimizations and fixes.
- #1132 Fixed build on CentOS 7.
- #1163 Optimized soft AES code, up to +30% hashrate on CPU without AES support and other optimizations.

#1142 RandomX hashrate improved by 0.5-1.5% depending on variant and CPU.
#1146 Fixed race condition in RandomX thread init.
#1148 Fixed, on Linux linker marking entire executable as having an executable stack.
Fixed, for Argon2 algorithms command line options like --threads was ignored.
Fixed command line options for single pool, free order allowed again.
