Pull request description:
This PR makes a number of improvements to the InvalidateBlock (`invalidateblock` RPC) and RewindBlockIndex functions, primarily around breaking up their long-term cs_main holding. In addition:
* They're made safely interruptible (`bitcoind` can be shutdown, and no progress in either will be lost, though if incomplete, `invalidateblock` won't continue after restart and will need to be called again)
* The validation queue is prevented from overflowing (meaning `invalidateblock` on a very old block will not drive bitcoind OOM) (see #14289).
* `invalidateblock` won't bother to move transactions back into the mempool after 10 blocks (optimization).
This is not an optimal solution, as we're relying on the scheduler call sites to make sure the scheduler doesn't overflow. Ideally, the scheduler would guarantee this directly, but that needs a few further changes (moving the signal emissions out of cs_main) to prevent deadlocks.
I have manually tested the `invalidateblock` changes (including interrupting, and running with -checkblockindex and -checkmempool), but haven't tried the rewinding (which is probably becoming increasingly unnecessary, as very few pre-0.13.1 nodes remain that would care to upgrade).

bf2e01097 uint256: Remove unnecessary crypto/common.h use (Karl-Johan Alm)
Pull request description:
This is an alternative to #13242 which keeps the `ReadLE64` part, but moves the `crypto/common.h` dependency into `crypto/common.h` as a function outside of `uint256`.
**Reason:** this change will remove dependencies for `uint256` to `crypto/common.h`, `compat/endian.h`, and `compat/byteswap.h`.
This PR removes the need to update tests to be endian-aware/-independent, but keeps the (arguably dubious) `ReadLE64` part (which was only introduced to fix the tests, not for any functionality).

6f6514a08090b37b5e8c086015ee4881813ef867 Correct units for "-dbcache" and "-prune" (Hennadii Stepanov)
Pull request description:
Actually, all `dbcache`-related values in the code are measured in MiB (not in megabytes, MB) or in bytes (e.g., `nTotalCache`).
See: https://github.com/bitcoin/bitcoin/blob/master/src/txdb.hba8c8b2227/src/init.cpp (L1405-L1424)
Also, "-prune" is fixed:
1. The GUI values in GB are translated to the node values in MiB correctly.
2. The maximum of the "prune" `QSpinBox` is not limited by default value of 99 (GB).

fa511e8dad Pass tx pool reference into CheckSequenceLocks (MarcoFalke)
Pull request description:
`CheckSequenceLocks` is called from ATMP and the member function `CTxMemPool::removeForReorg` without passing in the tx pool object that is used in those function's scope and instead using the global `::mempool` instance.
This fix should be refactoring only, since currently there is only one (global) tx pool in normal operation. Though, it fixes hard to track down issues in future settings where more than one mempool exists at a time. (E.g. for tests, rpc or p2p tx relay purposes)

The root of the issue come from the fact that all references to `DEFAULT_` are not in the scope of this file, so hard coding of default values are used everywhere in `net.cpp`. I think that in a separate PR we should fix that more fundamentally everywhere.

Pull request description:
use integer division instead of double conversion and multiplication for computing amounts. This will most likely generate identical code.
My main argument in favour of this change is one of purity, that we should not rely on implicit conversion from `CAmount` -> `double` and back again. Today this implicit conversion can happen because `CAmount` is just a typedef to `int64_t`. However, I envision a future where `CAmount` is a proper type that does not allow suspicious implicit conversions like these.

Pull request description:
Add compile time checking for `cs_main` runtime locking assertions.
This PR is a subset of #12665. The PR was broken up to make reviewing easier.
The intention is that literally all `EXCLUSIVE_LOCKS_REQUIRED`/`LOCKS_EXCLUDED`:s added in this PR should follow either directly or indirectly from `AssertLockHeld(…)`/`AssertLockNotHeld(…)`:s already existing in the repo.
Consider the case where function `A(…)` contains `AssertLockHeld(cs_foo)` (without
first locking `cs_foo` in `A`), and that `B(…)` calls `A(…)` (without first locking `cs_main`):
* It _directly_ follows that: `A(…)` should have an `EXCLUSIVE_LOCKS_REQUIRED(cs_foo)` annotation.
* It _indirectly_ follows that: `B(…)` should have an `EXCLUSIVE_LOCKS_REQUIRED(cs_foo)` annotation.

Pull request description:
I'm re-opening #11857 as a new pull request because the last one stopped loading for people
-------------------------------
This refactors the tx index code to be in it's own class and get built concurrently with validation code. The main benefit is decoupling and moving the txindex into a separate DB. The primary motivation is to lay the groundwork for other indexers that might be desired (such as the [compact filters](https://github.com/bitcoin/bips/pull/636)). The basic idea is that the TxIndex spins up its own thread, which first syncs the txindex to the current block index, then once in sync the BlockConnected ValidationInterface hook writes new blocks.
### DB changes
At the suggestion of some other developers, the txindex has been split out into a separate database. A data migration runs at startup on any nodes with a legacy txindex. Currently the migration blocks node initialization until complete.
### Open questions
- Should the migration of txindex data from the old DB to the new DB block in init or should it happen in a background thread? The downside to backgrounding it is that `getrawtransaction` would return an error message saying the txindex is syncing while the migration is running.
### Impact
In a sample size n=1 test where I synced nodes from scratch, the average time [Index writing](https://github.com/bitcoin/bitcoin/blob/master/src/validation.cpp#L1903) was 3.36ms in master and 1.72ms in this branch. The average time between `UpdateTip` log lines for sequential blocks between 400,000 and IBD end on mainnet was 0.297204s in master and 0.286134s in this branch. Most likely this is just variance in IBD times, but I can try with some more trials if people want.

b55555d rpc: Add testmempoolaccept (MarcoFalke)
Pull request description:
To check if a single raw transaction makes it into the current transaction pool, one had to call `sendrawtransaction`. However, on success, this adds the transaction to the mempool with no easy way to undo.
The call `testmempoolaccept` is introduced to provide a way to solely check the result without changing the mempool state.

Pull request description:
Since the actual block files taking up more and more space, it may be desirable to have them stored in a different location then the data directory (use case: SSD for chainstate, etc., HD for blocks).
This PR adds a `-blocksdir` option that allows one to keep the blockfiles and the blockindex external from the data directory (instead of creating symlinks).
I fist had an option to keep the blockindex within the datadir, but seems to make no sense since accessing the index will (always) lead to access (r/w) the block files.

Pull request description:
It has been brought up to my attention that current random delays mechanism (originally intended to obfuscate transaction metadata) allows to easily estimate the time a transaction was received by a node.
It may be done by connecting multiple observer nodes to the same node. Each of those nodes will generate its own schedule of delays. Combined metadata regarding those events from different sources allows an observer to estimate transaction time.
After this patch a spy won't gain additional information by just creating multiple connections to a target.

Pull request description:
CChainState should eventually, essentially, be our exposed "libconsensus", but we're probably a few releases away, so the real goal is to clarify our internal interfaces. The main split was a big step, but validation.cpp is still a somewhat ranomly-mixed bag of functions that are pure functions which validate inputs (which should probably either merge with their callers or move into another file in consensus/), read/write data from disk, manipulate our current chain state (which moves into CChainState), and do mempool transaction validation.
Obviously this is only a small step, but some effort is made to clean up what functions the functions in CChainState call, and obviously as things are added its easy to keep clear "CChainState::* cannot call anything except via callbacks through CValidationInterface, pure functions, or disk read/write things". Right now there are some glaring violations in mempool callbacks, and general flushing logic needs cleaning up (FlushStateToDisk maybe shouldnt be called, and there should be an API towards setDirtyBlockIndex, but I'll leave that for after @sipa's current changesets land).
