f137a35 Enforce restricted # pool txs served via RPC + optimize chunked reqs [release-v0.18] (j-berman)
23f782b wallet2, RPC: Optimize RPC calls for periodic refresh from 3 down to 1 call [release-v0.18] (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.

Before this change, if a multisig peer asked you to sign a transaction with a frozen enote, the wallet will do it without any error or warning. This change makes it
so that wallets will refuse to sign multisig transactions with frozen enotes.
Disclaimer: This PR was generously funded by @LocalMonero.
All Monero binaries have 1 second startup delay because of this code. This is especially noticeable and affects UX in Monero GUI wallet with local node where it often starts another monerod instance to run commands and query node status.
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.
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.
