* qt: Update the application font if the font family gets changed
* qt: Make sure recent transactions have the correct font family
Introduced because QListView is ignored in GUIUtil::updateFonts, so its base font family doesn't change, hence the recent transactions don't adjust because the painter's font doesn't change.
* Store initial font size

* Drop (no longer needed?) min height offset in SetupTransactionList

* Avoid recreating transaction filter from scratch every time SetupTransactionList is called
We call SetupTransactionList every second now (from privateSendStatus()) and this makes GUI unresponsive for huge wallets (I have ~400k txes in my testnet wallet) because of filter recreation/sorting. There is no need to go through all setup steps really, simply updating the limit works just fine and fixes the issue.

* bail out if `filter->rowCount() == nNumItems`
* qt: Make sure number of transactions is always correct

There is a bug in gdk-pixbuf which prevents ico files from being displayed correctly.
https://gitlab.gnome.org/GNOME/gdk-pixbuf/-/issues/86
Fixed by `convert bitcoin_testnet.ico[4] -define icon:auto-resize=256,128,64,48,32,16 bitcoin_testnet.ico`
* qt: Add missing changeEvent call in TransactionView
* qt: Use state related colors in TransactionModel
* qt: Don't colorize the text for abandoned transactions
The red icon should be obvious enough.
* qt: Drop InstantSend column from transaction view/model
* qt: Update verify.png
* qt: Extend the result string of TransactionTableModel::formatTxStatus
* qt: Drop "LLMQ based" in some status strings
* qt: Drop not longer needed ThemedColor entries
* Introduce amountColors(), add a case for `TransactionRecord::PrivateSendDenominate`
Avoid applying orange color to 0-fee mixing txes (PS denominate), use default (grey) color for them
* Tweak IS/CL status string additions a bit more
* Do not apply additional conditions, just use rec statuses
* qt: Adjust amount colors for types Generated and PrivateSendDenominate
Make them green/orange instead.
* Assign all colors explictly, drop default case
Let compiler complain about missing ones if any

* [wallet] Construct CWalletTx objects in CommitTransaction
Construct CWalletTx objects in CWallet::CommitTransaction, instead of having
callers do it. This ensures CWalletTx objects are constructed in a uniform way
and all fields are set.
This also makes it possible to avoid confusing and wasteful CWalletTx copies in
https://github.com/bitcoin/bitcoin/pull/9381
There is no change in behavior.
* [wallet] Get rid of CWalletTx default constructor
No change in behavior in the normal case. But buggy mapWallet lookups with
invalid txids will now throw exceptions instead of inserting dummy entries into
the map, and potentially causing segfaults and other failures.
This also makes it a compiler error to use the mapWallet[hash] syntax which
could create dummy entries.

I thought we had removed this a long time ago, TBH, its really
confusing feedback to users that we display whether a tx was
broadcast to immediate neighbor nodes, given that has little
indication of whether the tx propagated very far.

* net: Only open masternode connections if the blockchain is synced
In general it doesn't make sense to connect to masternodes before due to
MNAUTH requires blockchain sync. This could lead to failing quorum
connections/failing masternode
probing.. if a just restarted node/a out of sync node
would hit a dkg block.. Then they would not try to open those
llmq/probing connections for the next 60s (nLLMQConnectionRetryTimeout).

* test: Adjust last return in CreateTransaction
* test: Drop dust tests
* wallet: Remove unused vecTxDSInTmp in CWallet::CreateTransaction
* wallet: Calculate fees earlier and respect them in change determination
* wallet: Cleanup obsolete code in CreateTransaction
This parts were needed before when the fee was calculated after the
change was assigned. But now with the previous commit the fee is
calculated upfront and respected properly from the begining. So there is
no longer a need of increasing or decreasing the change depending on the
fee as it has the correct value directly after its added.
* wallet: Try to pick other inputs if the selected ones are too small
If nChange is negative in this cases it means that the selected inputs
can't cover the amount to send and the required transaction fee. So we
just add the missing amount to nFeeRet. This leads to the algo
trying to pick larger inputs in the next loop (with nFeeRet more duffs
than in the previous loop). This process gets repeated until the selected
amount is enough to cover all the costs or until the requested amount
can't be selected anymore (not enough utxos to cover it).
* wallet: Break the loop if the transaction is ready
* wallet: Respect additional amount from previous cycles
* wallet: Respect available in coin selection, try all coins in last round
* wallet: Avoid potential infinite loop, just in case..
* wallet: Fix signing in CreateTransaction

pick wrong coins for signing the input.
* wallet: Fix change calculation if "subtract fee from amount" is enabled
* wallet: Return after fee calc if no or not enough amount available

fee from amount.

Spork6 was previously activated on testnet, but we then developed an alternative fix for the issue and never activated spork6 on mainnet. At this point, Spork6 will not be activated on mainnet.
As such, it makes sense to harden Spork6 and ensure that spork6 will never be activated on mainnet. So, we just change from checking Spork6 to checking if we are on testnet. If we are on testnet, use spork6 logic, else don't.

* Add "ps_salt" value to walletdb
This value is used to deterministically pick a random number of rounds to mix, between N and N + GetRandomRounds. A salt is needed in addition to the inputs hash to ensure that an attacker learns nothing from looking at the blockchain.
Signed-off-by: pasta <pasta@dashboost.org>
* Implement Random Round Mixing
This implements "Random Round Mixing." Previously, attempted attacks on PrivateSend assumed that all inputs had been mixed for the same number of rounds. Noramlly assuming 2,4,8 or 16.
While none of these attacks have been successful, they still teach what we can do to make our system more robust, and one of those ways is to implement "Random Round Mixing".
Under the previous system, inputs were mixed up until N rounds (configured by user). At this point, the input was considered mixed, and could be private-sent. Under this new system, an input will be mixed to N rounds like prior. However, at this point, Sha256d(input, salt) will be calculated (note: this likely could be a more efficient hash function than double sha256, but that can be done in another PR / version if needed). If (hash % 2 == 0), then the input will be mixed again.
This results in an exponential decay where if you mix a set of inputs, half of those inputs will be mixed for N rounds, 1/4 will be mixed N+1, 1/8 will be mixed N+2, etc. This current implementation caps it at N+2. This results in mixing an average of N+0.875 rounds. If you removed the cap, you would mix on average N+1 rounds.
