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.

- Detach & re-process txs >= lowest scan height
- ensures that if a user calls scan_tx(tx1) after scanning tx2,
the wallet correctly processes tx1 and tx2
- if a user provides a tx with a height higher than the wallet's
last scanned height, the wallet will scan starting from that tx's
height
- scan_tx requires trusted daemon iff need to re-process existing
txs: in addition to querying a daemon for txids, if a user
provides a txid of a tx with height *lower* than any *already*
scanned txs in the wallet, then the wallet will also query the
daemon for all the *higher* txs as well. This is likely
unexpected behavior to a caller, and so to protect a caller from
revealing txid's to an untrusted daemon in an unexpected way,
require the daemon be trusted.
