Calling ActiveHeight() and ActiveTip() subsequently without holding the
::cs_main lock over both calls may result in a height that does not
correspond to the tip due to a race.
Fix this by holding the lock.
ActiveTip() is *not* thread-safe, as the required ::cs_main lock will be
released as ActiveChainstate() returns.
ActiveTip() is an alias for ActiveChainstate().m_chain.Tip(), so m_chain
may be involved in a data-race (UB).
The test is a bit primitive as it checks the Bitcoin Core log and
assumes that if it logs that it creates a transient session, then it
does that indeed.
A more thorough test would be to check that it indeed sends the
`SESSION CREATE ... DESTINATION=TRANSIENT` command and that it uses
the returned I2P address for connecting, even for repeated connections
to the same I2P peer. That would require a mocked SAM server (proxy)
implementation in Python.
If not accepting I2P connections, then do not create
`CConnman::m_i2p_sam_session`.
When opening a new outbound I2P connection either use
`CConnman::m_i2p_sam_session` like before or create a temporary one and
store it in `CNode` for destruction later.
and destroy it when `CNode::m_sock` is closed.
I2P transient sessions are created per connection (i.e. per `CNode`) and
should be destroyed when the connection is closed. Storing the session
in `CNode` is a convenient way to destroy it together with the connection
socket (`CNode::m_sock`).
An alternative approach would be to store a list of all I2P sessions in
`CConnman` and from `CNode::CloseSocketDisconnect()` to somehow ask the
`CConnman` to destroy the relevant session.

98383d6d0d doc: minor updates to guix README (Stacie)
Pull request description:
Two minor updates to the guix docs:
- `contrib/guix/README.md`: fix broken link
- `contrib/guix/INSTALL.md`: Change Ubuntu version in the section on distribution maintained packages from 21.04 (Hirsute Hippo) to 22.04 (Jammy Jellyfish). The previous link to the Ubuntu Guix package (https://packages.ubuntu.com/hirsute/guix) was for Hirsute. That link is now broken, likely because Hirsute reached EOL in January. I was unable to locate a general page for Ubuntu Guix packages so I replaced the broken link with the search results for all Ubuntu Guix packages. That page currently displays Guix packages for three different versions of Ubuntu. Happy to replace this link if there is a better option.

f6a916683d Add functional test for block announcements during initial headers sync (Suhas Daftuar)
05f7f31598 Reduce bandwidth during initial headers sync when a block is found (Suhas Daftuar)
Pull request description:
On startup, if our headers chain is more than a day behind current time, we'll pick one peer to sync headers with until our best headers chain is caught up (at that point, we'll try to sync headers with all peers).
However, if an INV for a block is received before our headers chain is caught up, we'll then start to sync headers from each peer announcing the block. This can result in doing a big headers sync with many (if not all) of our peers simultaneously, which wastes bandwidth.
This PR would reduce that overhead by picking (at most) one new peer to try syncing headers with whenever a new block is announced, prior to our headers chain being caught up.

e62958dc81 GUI: sendCoinsDialog, remove duplicate wallet().getBalances() call (furszy)
Pull request description:
As per the title says, we are recalculating the entire wallet balance on different situations calling to `wallet().getBalances()`, when should instead make use of the wallet model cached balance.
This has the benefits of (1) not spending resources calculating a balance that we already have cached, and (2) avoid blocking the main thread for a long time, in case of big wallets, walking through the entire wallet's tx map more than what it's really needed.
Changes:
1) Fix: `SendCoinsDialog` was calling `wallet().getBalances()` twice during `setModel`.
2) Use the cached balance if the user did not select any UTXO manually inside the wallet model `getAvailableBalance` call.

When we have preselected inputs the coin selection search target is reduced
by the sum of (effective) values. This causes incorrect m_target value.
Create separate instance of SelectionResult for all the preselected inputs and
set the target equal to the sum of (effective) values. Target for preselected
SelectionResult is equal to the delta for the search target. To get the final
SelectionResult with accurate m_target we merge both SelectionResult instances.
SelectionResult::m_target should be equal to actual selection target.
Selection target is the sum of all recipient amounts plus non input fees.
So we need to remove change_fee from the m_target. It's safe because change
target is always greater than the change fee, so we can always cover fees
if change output is created.
292b1a3e9c GetExternalSigner(): fail if multiple signers are found (amadeuszpawlik)
Pull request description:
If there are multiple external signers, `GetExternalSigner()` will
just pick the first one in the list. If the user has two or more
hardware wallets connected at the same time, he might not notice this.
This PR adds a check and fails with suitable message, forcing the user to disconnect all but one external signer, so that there is no ambiguity as to which external signer was used.

If our headers chain is behind on startup, then if a block is found we'll try
to catch up from all peers announcing the block, in addition to our initial
headers-sync peer. This commit changes behavior so that in this situation,
we'll choose at most one peer announcing a block to additionally sync headers
from.
Plus, calculate the cached balance right when the wallet model, so the wallet widgets don't need to redo the same balance calculation multiple times when they are waiting for the model balance polling timer.
----------------------------------------------------------------------
test wise: `WalletTests` now need to trigger the walletModel balance changed manually. So the model updates its internal state and can be used by the widgets.
This is because the test does not start the balance polling timer, in the same way as does not initialize several parts of the GUI workflow. All the objects (wallet, models, views, etc) that are used on this test are manually created instead of using the `WalletController` class flow.
Rationale is that this unit test is focused on verifying the GUI widgets/views behavior only: update the presented information, etc. when they receive different signals and/or function calls from outside (in other words, focus is on the signal slots/receiver side). It's not about whether the wallet balance polling timer is functioning as expected or not (which we definitely create a new test case for it in a follow-up work).
Inside setModel, we call 'wallet().getBalances()', to set the view balance,
right before calling 'updateDisplayUnit' which calls 'wallet().getBalances()'
internally and re-sets the view balance again.
