b27a17110d RandomX: print VM allocation warnings only once 2023-01-11 19:15:11 +01:00

dab7d01dc0 Refactored rx-slow-hash.c 
- Straight-forward call interface: `void rx_slow_hash(const char *seedhash, const void *data, size_t length, char *result_hash)`
- Consensus chain seed hash is now updated by calling `rx_set_main_seedhash` whenever a block is added/removed or a reorg happens
- `rx_slow_hash` will compute correct hash no matter if `rx_set_main_seedhash` was called or not (the only difference is performance)
- New environment variable `MONERO_RANDOMX_FULL_MEM` to force use the full dataset for PoW verification (faster block verification)
- When dataset is used for PoW verification, dataset updates don't stall other threads (verification is done in light mode then)
- When mining is running, PoW checks now also use dataset for faster verification

crypto: fix constant randomx exceptions in large page allocator 
If allocating large pages fails, we don't try again.
This has the obvious drawback of not being able to use large pages
if they fail once.

Fix for miners on reorg 
Make sure dataset gets re-init'd if a reorg changes the epoch

Update to RandomX v1.1.3, simplify 
We don't need to detect if the cache has changed, just always
call to set it on the VM. The call will be a no-op if the cache
hasn't changed.
