The gamma picker and the caller code did not quite agree on the
number of rct outputs available for use - by one block - which
caused an infinite loop if the picker could never pick outputs
from that block but already had picked all other outputs from
previous blocks.
Also change the range to select from using code from UkoeHB.
It's not allowed to use WaitForSingleObject with _beginthread, because the thread closes its own handle before exiting.
So the wait function will either wait on an invalid handle, or on a different handle used by something else.
Or, if it starts waiting before the thread exits, the behavior is undefined according to MS: "If this handle is closed while the wait is still pending, the function's behavior is undefined."
In my test sync I observed threads getting stuck infinitely on WaitForSingleObject, and then rx_set_main_seedhash spamming new threads when RandomX seed changes again. Eventually the system ran out of resources, and monerod aborted with "Couldn't start RandomX seed thread" message.
This PR fixes it by using `_beginthreadex` instead and explicitly closing the handle when it's safe.

c4af33e Enforce restricted # pool txs served via RPC + optimize chunked reqs (j-berman)
9752116 wallet2, RPC: Optimize RPC calls for periodic refresh from 3 down to 1 call (rbrunner7)
- `/getblocks.bin` respects the `RESTRICTED_TX_COUNT` (=100) when
returning pool txs via a restricted RPC daemon.
- A restricted RPC daemon includes a max of `RESTRICTED_TX_COUNT` txs
in the `added_pool_txs` field, and returns any remaining pool hashes
in the `remaining_added_pool_txids` field. The client then requests
the remaining txs via `/gettransactions` in chunks.
- `/gettransactions` no longer does expensive no-ops for ALL pool txs
if the client requests a subset of pool txs. Instead it searches for
the txs the client explicitly requests.
- Reset `m_pool_info_query_time` when a user:
(1) rescans the chain (so the wallet re-requests the whole pool)
(2) changes the daemon their wallets points to (a new daemon would
have a different view of the pool)
- `/getblocks.bin` respects the `req.prune` field when returning
pool txs.
- Pool extension fields in response to `/getblocks.bin` are optional
with default 0'd values.
- 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
For privacy reasons, time functions use GMT, to avoid logs leaking
timezones. It'd make more sense to use localtime for wallet output
(which are not logged by default), but that adds inconsistencies
which can also be confusing. So add a Z suffix for now to make it
clear these are not local time.
Unrelated, but similar code-wise to #8643. There is a check in `DNSResolver` which automatically fails to resolve hostnames which do not contain the `.` character. This PR removes that check.
Fixes#8633. The function `append_net_address` did not parse hostname + port addresses (e.g. `bar:29080`) correctly if the hostname did not contain a `'.'` character.

clear up 2nd conditional statement
- fix integrated address test, it was not testing integrated address suport
- fix trezor test build as dependent classes were changed
- add a friend test class for Monero::WalletImpl to support wallet api tests
When using wallet_api in tests, synthetic chain is used. Without being able to set `allow_mismatched_daemon_version` in the underlying wallet, we are not able to use a synthetic chain with the tests
23fde15 wallet_rpc_server: chunk refresh to keep responding to RPC while refreshing (moneromooo-monero) 5bb2369 wallet_rpc_server: add --no-initial-sync flag for quicker network binding (moneromooo-monero)
update_checkpoints() makes a few DNS requests and can take up to 20-30 seconds to complete (3-6 seconds on average). It is currently called from core::handle_incoming_block() which holds m_incoming_tx_lock, so it blocks all incoming transactions and blocks processing while update_checkpoints() is running. This PR moves it to until after a new block has been processed and relayed, to avoid full monerod locking.

- spend secret key is no longer the sum of multisig key shares;
no need to check that is the case upon restore.
- restoring a multisig wallet from multisig info means that the
wallet must have already completed all setup rounds. Upon restore,
set the number of rounds completed accordingly.
600de07 wallet_rpc_server: longer timeout for stop_mining (moneromooo-monero)
ac6db92 functional_tests: silence the cpu power test program (moneromooo-monero)
Being offline is not a good enough heuristic, so we keep track
of whether the wallet ever refreshed from a daemon, which is a
lot better, and probably the best we can do without manual user
designation (which would break existing cold wallet setups till
the user designates those wallets)
Before the fix, it processed all transactions in the mempool which could be very slow when mempool grows to several MBs in size. I observed `get_block_template_backlog` taking up to 15 seconds of CPU time under high mempool load.
After the fix, only transactions that can potentially be mined in the next block will be processed (a bit more than the current block median weight).
That RPC will wait for mining to actually stop, which can be a while
if randomx has just started on randomx_init_dataset.
This fixes occasional failures in the mining functional test
