fa996c58e8 refactor: Avoid integer overflow in ApplyStats when activating snapshot (MarcoFalke)
fac01888d1 Move AdditionOverflow to util, Add CheckedAdd with unit tests (MarcoFalke)
fa526d8fb6 Add dev doc to CCoinsStats::m_hash_type and make it const (MarcoFalke)
faff051560 style: Remove unused whitespace (MarcoFalke)
Pull request description:
A snapshot contains the utxo set, including the out value. To activate the snapshot, the hash needs to be calculated. As a side-effect, the total amount in the snapshot is calculated (as the sum of all out values), but never used. Instead of running into an integer overflow in an unused result, don't calculate the result in the first place.
Other code paths (using the active utxo set) can not run into an integer overflow, since the active utxo set is valid.

dad5f76021 addrman: Introduce a test-only function to lookup addresses (Amiti Uttarwar)
Pull request description:
This PR (joint work with Amiti Uttarwar) changes the addrman unit tests such that they only use the public `AddrMan` interface:
This has the advantage that the tests are less implementation-dependent, i.e. it would be possible to rewrite the internal addrman implementation (as drafted [here](https://github.com/sipa/bitcoin/tree/202106_multiindex_addrman) for using a multiindex) without having to adjust the tests.
This includes the following steps:
* Adding a test-only function `FindAddressEntry()` to the public addrman interface which returns info about an address in addrman (e.g. bucket, position, whethe the address is in new or tried). Obviously we want to do this sparingly, but I think a single test-only function is ok (which could also be useful elsewhere, e.g. in fuzz tests).
* Removal of the `AddrManTest` subclass which would reach into AddrMan's internals, using `AddrMan` instead
* Removal of tests for internal helper functions that are not publicly exposed (these are still tested indirectly via the public functions calling them).
* Additional tests for previously untested features such as multiplicity in the new tables, that can be tested with the help of `FindAddressEntry()`.
All in all, this PR increases the unit test coverage of AddrMan by a bit.

29e1794ba5 build, qt: No need to set inapplicable QPA backend for Android (Hennadii Stepanov)
Pull request description:
The current workflow looks weird. At first, the inapplicable `xcb` QPA backend is set in Qt `configure` options. Then the correct `android` QPA backend is forced via the `QT_QPA_PLATFORM` environment variable.
Using the default QPA backend, which is `android` for Android devices, is just fine.

b4adc5ad67 [bugfix] update lockpoints correctly during reorg (glozow)
b6002b07a3 MOVEONLY: update_lock_points to txmempool.h (glozow)
Pull request description:
I introduced a bug in #22677 (sorry! 😅)
Mempool entries cache `LockPoints`, containing the first height/blockhash/`CBlockIndex*` at which the transaction becomes valid. During a reorg, we re-check timelocks on all mempool entries using `CheckSequenceLocks(useExistingLockPoints=false)` and remove any now-invalid entries. `CheckSequenceLocks()` also mutates the `LockPoints` passed in, and we update valid entries' `LockPoints` using `update_lock_points`. Thus, `update_lock_points(lp)` needs to be called right after `CheckSequenceLocks(lp)`, otherwise we lose the data in `lp`. I incorrectly assumed they could be called in separate loops.
The incorrect behavior introduced is: if we have a reorg in which a timelocked mempool transaction is still valid but becomes valid at a different block, the cached `LockPoints` will be incorrect.
This PR fixes the bug, adds a test, and adds an assertion at the end of `removeForReorg()` to check that all mempool entries' lockpoints are valid. You can reproduce the bug by running the test added in the [test] commit on the code before the [bugfix] commit.

The logic of these functions is already covered by existing unit tests
using publicly exposed functions of the interface.
Therefore, removing them does not decrease test coverage.
Switches to AddrMan for tests that use no features of AddrManTest.
Also removes unusued AddrManTest variables

7b481f015a Fix Racy ParseOpCode function initialization (Jeremy Rubin)
Pull request description:
If multiple callers call ParseOpCode concurrently it will cause a race condition. We can either move the static to it's own area and require init be called explicitly, or just allow concurrent first callers to race to fill in an atomic variable that never changes thereafter. The second approach is taken here.
Static initialization *is* threadsafe, but only insofar as definining the variable being guaranteed to be called once. This is used incorrectly here.
