1ef28b4f7c Make AnalyzePSBT next role calculation simple, correct (Gregory Sanders)
Pull request description:
Sniped test and alternative to https://github.com/bitcoin/bitcoin/pull/18220
Sjors documenting the issue:
```
A PSBT signed by ColdCard was analyzed as follows (see #17509 (comment))
{
"inputs": [
{
"has_utxo": true,
"is_final": false,
"next": "finalizer"
}
],
"estimated_vsize": 141,
"estimated_feerate": 1e-05,
"fee": 1.41e-06,
"next": "signer"
}
I changed AnalyzePSBT so that it returns "next": "finalizer" instead.
```
It makes it much clearer that the role has been decided before hitting the `calc_fee` block, and groups all state-deciding in one spot instead of 2.
Note that this assumes that PSBT roles are a complete ordering, which for now and in the future seems to be a correct assumption.

Pull request description:
This PR is to support functional tests by allowing the scheduler to be mocked via the RPC.
It adds a `MockForward` method to the scheduler class that iterates through the task queue and reschedules them to be `delta_seconds` sooner.
This is currently used to support functional testing of the "unbroadcast" set tracking in #18038. If this patch is accepted, it would also be useful to simplify the code in #16698.

deaa6dd144 psbt: check output index is within bounds before accessing (Andrew Chow)
f1ef7f0aa4 Don't calculate tx fees for PSBTs with invalid money values (Andrew Chow)
Pull request description:
Fixes#17149
Two classes of issues were found by the psbt fuzzer: values out of range and causing overflows, and prevout indexes being out of range. This PR fixes both.
When accessing a specific output using the index given in the tx, check that it is actually a possible output before trying to access the output.
When summing and checking amounts for `decodepsbt` and `analyzepsbt`, make sure that the values are actually valid money values.. Otherwise, stop summing and don't show the fee. For `analyzepsbt`, return that the next role is the Creator since the Creator needs to remake the transaction to be valid.

In decodepsbt if an invalid amount is seen, don't calculate the fee
but still show the invalid value in the decode.
In analyze psbt, if an invalid amount is seen, set the next step to
be the creator as the creator needs to remake the transaction so that
it is valid.

Invalid PSBTs need to be re-created, so the next role is the
Creator (new PSBTRole). Additionally, we need to know what went
wrong so an error field was added to PSBTAnalysis.
A PSBTAnalysis indicating invalid will have empty everything,
next will be set to PSBTRole::CREATOR, and an error message.
Currently it is an alias to the global ::mempool and should be used as
follows.
* Node code (validation and transaction relay) can use either ::mempool
or node.mempool, whichever seems a better fit.
* RPC code should use the added convenience getter EnsureMempool, which
makes sure the mempool exists before use. This prepares the RPC code
to a future where the mempool might be disabled at runtime or compile
time.
* Test code should use m_node.mempool directly, as the mempool is always
initialized for tests.

This changeset defines the serialization format for UTXO snapshots and adds an RPC command for creating them, `dumptxoutset`. It also adds a convenience script for generating and verifying snapshots at a certain height, since that requires doing a hacky rewind of the chain via `invalidateblock`.
All of this is unused at the moment.

Pull request description:
Carries out some remaining tidy-ups remaining after PR 15141:
- split ValidationState into TxValidationState and BlockValidationState (commit from ajtowns)
- various minor code style tidy-ups to the ValidationState class
- remove the useless `ret` parameter from `ValidationState::Invalid()`
- remove the now unused `first_invalid` parameter from `ProcessNewBlockHeaders()`
- remove the `fMissingInputs` parameter from `AcceptToMemoryPool()`, and deal with missing inputs the same way as other errors by using the `TxValidationState` object.
Tip for reviewers (thanks ryanofsky!): The first commit ("[validation] Add CValidationState subclasses" ) is huge and can be easier to start reviewing if you revert the rote, mechanical changes:
Substitute the commit hash of commit "[validation] Add CValidationState subclasses" for <CommitHash> in the commands below.
```sh
git checkout <CommitHash>
git grep -l ValidationState | xargs sed -i 's/BlockValidationState\|TxValidationState/CValidationState/g'
git grep -l ValidationResult | xargs sed -i 's/BlockValidationResult\|TxValidationResult/ValidationInvalidReason/g'
git grep -l MaybePunish | xargs sed -i 's/MaybePunishNode\(ForBlock\|ForTx\)/MaybePunishNode/g'
git diff HEAD^
```
After that it's possible to easily see the mechanical changes with:
```sh
git log -p -n1 -U0 --word-diff-regex=. <CommitHash>
```

These procedures will later be used in the ChainstateManager to compute
statistics (particularly a content hash) for UTXO sets coming in from
snapshots.

This change encapsulates UTXO set data within CChainState instances, removing global data `pcoinsTip` and `pcoinsviewdb`. This is necessary if we want to maintain multiple chainstates with their own rendering of the UTXO set.
We introduce a class CoinsViews which consolidates the construction of a CCoins* hierarchy.
This commit could be broken into smaller pieces, but it would require more ephemeral diffs to, e.g., temporarily change CCoinsViewDB's constructor invocations.

RPC server starts in warmup mode, it can't
process yet calls, then follows connection manager
initialization and finally RPC server get out of
warmup mode. RPC calls shouldn't be able to get
P2P disabled errors because once we initialize
g_connman it's not unset until shutdown, after
RPC server has been stopped.
Access through a broadcastTransaction method.
Add a wait_callback flag to turn off race protection when wallet
already track its tx being in mempool
Standardise highfee, absurdfee variable name to max_tx_fee
We drop the P2P check in BroadcastTransaction as g_connman is only
called by RPCs and the wallet scheduler, both of which are initialized
after g_connman is assigned and stopped before g_connman is reset.
psbt.cpp definitions except for AnalyzePSBT are used by the wallet and need to
be linked into the wallet binary. AnalyzePSBT is an exception in that it is not
used by the wallet, and depends on node classes like CCoinsViewCache, and on
node global variables like nBytesPerSigOp.
So AnalyzePSBT is more at home in libbitcoin_server than libbitcoin_common, and
in any case needs to be defined in a separate object file than other PSBT
utilities, to avoid dragging link dependencies on node functions and global
variables into the wallet.
Adds the following util units and adds them to libbitcoin_util:
- `util/url.cpp` takes `urlDecode` from `httpserver.cpp`
- `util/error.cpp` takes `TransactionErrorString` from
`node/transaction.cpp` and `AmountHighWarn` and `AmountErrMsg` from
`ui_interface.cpp`
- `util/fees.cpp` takes `StringForFeeReason` and `FeeModeFromString` from `policy/fees.cpp`
- `util/rbf.cpp` takes `SignalsOptInRBF` from `policy/rbf.cpp`
- 'util/validation.cpp` takes `FormatStateMessage` and `strMessageMagic` from 'validation.cpp`
Refactor the new CombinePSBT, FinalizePSBT, and FinalizeAndExtractPSBT
general-purpose functions out of the combinepsbt and finalizepsbt RPCs,
for use in the GUI code.
After refactoring general-purpose PSBT and transaction code out of RPC code,
for use in the GUI, it's no longer appropriate to throw exceptions. Instead we
now return bools for success, and take an output parameter for an error object.
We still use JSONRPCError() for the error objects, since only RPC callers
actually care about the error codes.
Factor out a new BroadcastTransaction function, performing the core work of the
sendrawtransaction rpc, so that it can be used from the GUI code. Move it from
src/rpc/ to src/node/.
