Pull request description:
This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):
Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal
---
This changeset introduces `ChainstateManager`, which is responsible for creating and managing access to multiple chainstates. Until we allow chainstate creation from UTXO snapshots (next assumeutxo PR?) it's basically unnecessary, but it is a prerequisite for background IBD support.
Changes are also made to the initialization process to make use of `g_chainman` and thus clear the way for multiple chainstates being loaded on startup.
One immediate benefit of this change is that we no longer have the `g_blockman` global, but instead have the ChainstateManager inject a reference of its shared BlockManager into any chainstate it creates.
Another immediate benefit is that uses of `ChainActive()` and `ChainstateActive()` are now covered by lock annotations. Because use of `g_chainman` is annotated to require cs_main, these two functions subsequently follow.
Because of whitespace changes, this diff looks bigger than it is. E.g., 4813167d98 is most easily reviewed with
```sh
git show --color-moved=dimmed_zebra -w 4813167d98

01a3392b1b Drop bitcoin-wallet dependency on libevent (Russell Yanofsky)
0660119ac3 Drop unintended bitcoin-tx dependency on libevent (Russell Yanofsky)
Pull request description:
This fixes compile errors trying to build bitcoin-tx and bitcoin-wallet without libevent, which were reported by Luke Dashjr in https://github.com/bitcoin/bitcoin/issues/18465
The fix avoiding `bitcoin-tx` dependency on libevent just adds a conditional build rule. This is implemented in the first commit (more details in commit description).
The fix avoiding `bitcoin-wallet` dependency on libevent requires minor code changes, because `bitcoin-wallet` (unlike `bitcoin-tx`) links against code that calls `urlDecode` / `evhttp_uridecode`. This fix is implemented in the second commit (again details in the commit description).

Don't require urlDecode function in wallet code since urlDecode implementation
currently uses libevent. Just call urlDecode indirectly though URL_DECODE
function pointer constant if available.
In bitcoind and bitcoin-qt, URL_DECODE is implemented and used to interpret RPC
wallet requests. In bitcoin-wallet, URL_DECODE is null to avoid depending on
libevent.

Calling interrupt_all() will immediately stop the scheduler, so it's
safe to invoke stop() beforehand, and this removes the reliance on boost
to interrupt serviceQueue().

The only difference between SetupDummyInputs() in test/transaction_tests.cpp
and the one in bench/ccoins_caching.cpp was the nValue amounts of the outputs,
so we allow to pass those in an extra (fixed-size) array parameter.

a6f63598ad [util] allow scheduler to be mocked (Amiti Uttarwar)
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.

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.
fae43a97ca test: Seed test RNG context for each test case, print seed (MarcoFalke)
Pull request description:
Debugging failing unit tests is hard if the failure is non-deterministic and the seed is not known.
Fix that by printing the seed and making it possible to set the seed from outside.
