4a1b2a7ba7f804e656a8cd29d5aa80fcbd40904f [GetTransaction] remove unneeded `cs_main` lock acquire (Sebastian Falbesoner)
Pull request description:
This PR is a follow-up to #22383. For reading from the mempool, only `mempool.cs` needs to be locked (see [suggestion by MarcoFalke](https://github.com/bitcoin/bitcoin/pull/22383#discussion_r675069128)):
b620b2d58a/src/txmempool.h (L554-L558)
`CTxMemPool::get()` acquires this lock:
b620b2d58a/src/txmempool.cpp (L822-L829)
so we don't need to acquire any lock ourselves in `GetTransaction()`, as the other functions called in the remaining parts also don't need to have `cs_main` locked.

7b3a20b2602f902c344a615f23f8f0280b6f6bcc mempool: apply rule of 5 to epochguard.h, fix compiler warnings (Jon Atack)
Pull request description:
Apply the rule of five to `src/util/epochguard.h::{Epoch, Marker}` for safety, which also nicely fixes the `-Wdeprecated-copy` compiler warnings with Clang 13.

9b85a5e2f7e003ca8621feaac9bdd304d19081b4 tests: Test for dumpwallet lock order issue (Andrew Chow)
25d99e6511d8c43b2025a89bcd8295de755346a7 Reorder dumpwallet so that cs_main functions go first (Andrew Chow)
Pull request description:
When a wallet is loaded which has an unconfirmed transaction in the mempool, it will end up establishing the lock order of cs_wallet -> cs_main -> cs_KeyStore. If `dumpwallet` is used on this wallet, then a lock order of cs_wallet -> cs_KeyStore -> cs_main will be used, which causes a lock order assertion. This PR fixes this by reordering `dumpwallet` and `GetKeyBirthTimes` (only used by `dumpwallet`). Specifically, in both functions, the function calls which lock cs_main are done prior to locking cs_KeyStore. This avoids the lock order issue.
Additionally, I have added a test case to `wallet_dump.py`. Of course testing this requires `--enable-debug`.

## Issue being fixed or feature implemented
Platform (in the scope of Withdrawals) need to be aware if a tx isn't in
mempool when requesting status of a tx using RPC `gettxchainlocks`.
cc @markin-io
## What was done?
- mempool is passed to `GetTransaction` and saving the result for
checking latter.
- If the returned tx_ref is nullptr, then the RPC returns null for the
corresponding tx in the array.
Example:
`tx1` is mined and chainlocked, `tx2` is in mempool and `tx3` doesn't
exist.
The result now is:
`[
{
"height": 830,
"chainlock": false,
"mempool": true
},
{
"height": -1,
"chainlock": false,
"mempool": true
},
{
"height": -1,
"chainlock": false,
"mempool": false
}
]`

## Issue being fixed or feature implemented
Platform in the scope of credit withdrawals, need a way to get the
status of an Asset Unlock by index.
## What was done?
A new RPC was created `getassetunlockchainlocks` that accepts Asset
Unlock indexes array as parameter and return corresponding status for
each index.
The possible outcomes per each index are:
- `chainlocked`: If the Asset Unlock index is mined on a Chainlocked
block.
- `mined`: If no Chainlock information is available, and the Asset
Unlock index is mined.
- `mempooled`: If the Asset Unlock index is in the mempool.
- `unknown`: If none of the above are valid.
Note: This RPC is whitelisted for the Platform RPC user.
## How Has This Been Tested?
Inserted on `feature_asset_locks.py` covering cases where Asset Unlock
txs are in mempool, mined and not present.
## Breaking Changes
no

## Issue being fixed or feature implemented
Cache population for old quorums is a cpu heavy operation and should be
avoided for inactive quorums _at least_ oin `ScanQuorums`. This issue is
critical for testnet and other small network because every mn
participate in almost every platform quorum and cache population for 2
months of quorums can easily block everything for 15+ minutes on a 4 cpu
node. On mainnet quorum distribution is much better but it's still a
small waste of cpu (or not so small for unlucky nodes).
#5761 follow-up
## What was done?
Do not start cache population for outdated quorums, improve logs in
`StartCachePopulatorThread` to make it easier to see what's going on.
## How Has This Been Tested?
run a mn on testnet

Impossible to drop it completelly right now because:
- net doesn't know any details about chain - can't check status of fork
- the functional test feature_maxuploadtarget.py assume block size 1Mb
- DIP0001 can't be activated from regtest early block2 because big txes are
not allowed after DIP0001
refactor: drop global variable fDIP0001ActiveAtTip - attempt 2
