67d99900b0d770038c9c5708553143137b124a6c make SaltedOutpointHasher noexcept (Martin Ankerl)
Pull request description:
If the hash is not `noexcept`, `unorderd_map` has to assume that it can throw an exception. Thus when rehashing care needs to be taken. libstdc++ solves this by simply caching the hash value, which increases memory of each node by 8 bytes. Adding `noexcept` prevents this caching. In my experiments with `-reindex-chainstate -stopatheight=594000`, memory usage (maximum resident set size) has decreased by 9.4% while runtime has increased by 1.6% due to additional hashing. Additionally, memusage::DynamicUsage() is now more accurate and does not underestimate.

efd2474d17098c754367b844ec646ebececc7c74 util: CBufferedFile fixes (Larry Ruane)
Pull request description:
The `CBufferedFile` object guarantees its user is able to "rewind" the data stream (that's being read from a file) up to a certain number of bytes, as specified by the user in the constructor. This guarantee is not honored due to a bug in the `SetPos` method.
Such rewinding is done in `LoadExternalBlockFile()` (currently the only user of this object), which deserializes a series of `CBlock` objects. If that function encounters something unexpected in the data stream, which is coming from a `blocks/blk00???.dat` file, it "rewinds" to an earlier position in the stream to try to get in sync again. The `CBufferedFile` object does not actually rewind its file offset; it simply repositions its internal offset, `nReadPos`, to an earlier position within the object's private buffer; this is why there's a limit to how far the user may rewind.
If `LoadExternalBlockFile()` needs to rewind (call `blkdat.SetPos()`), the stream may not be positioned as it should be, causing errors in deserialization. This need to rewind is probably rare, which is likely why this bug hasn't been noticed already. But if this object is used elsewhere in the future, this could be a serious problem, especially as, due to the nature of the bug, the `SetPos()` _sometimes_ works.
This PR adds a unit test for `CBufferedFile` that fails due to this bug. (Until now it has had no unit tests.) The unit test provides good documentation and examples for developers trying to understand `LoadExternalBlockFile()` and for future users of this object.
This PR also adds code to throw an exception from the constructor if the rewind argument is not less than the buffer size (since that doesn't make any sense).
Finally, I discovered that the object is too restrictive in one respect: When the deserialization methods call this object's `read` method, a check ensures that the number of bytes being requested is less than the size of the buffer (adjusting for the rewind size), else it throws an exception. This restriction is unnecessary; the object being deserialized can be larger than the buffer because multiple reads from disk can satisfy the request.

fa607c229295e0f0b89d5177b94d3381ab5e37d8 validation: Make GetWitnessCommitmentIndex public (MarcoFalke)
Pull request description:
`GenerateCoinbaseCommitment` is public and can be used in unit tests to update the witness commitment after the list of txs in a block has been changed. However, for it to work, the existing commitment (added by default in `CreateNewBlock`) must be removed (and thus its index must be known).
Make that possible by exposing the `GetWitnessCommitmentIndex` helper function in the header.

6170ec5d3ac2bc206068b270e5722a7ecd3a8f26 Do not query all DNS seed at once (Pieter Wuille)
Pull request description:
Before this PR, when we don't have enough connections after 11 seconds, we proceed to query all DNS seeds in a fixed order, loading responses from all of them.
Change this to to only query three randomly-selected DNS seed. If 11 seconds later we still don't have enough connections, try again with another one, and so on.
This reduces the amount of information DNS seeds can observe about the requesters by spreading the load over all of them.

Fixes https://github.com/bitcoin/bitcoin/issues/16382
This patch tries to treat `maxfeerate` in sendrawtransaction/testmempoolaccept RPC as a rate(BTC/kB) instead of an absolute value(BTC).
The included test case checks if the new behavior works correctly, by using the transaction with an absolute fee of ~0.02BTC, where the fee rate is ~0.2BTC/kB.
This test should be failing if the default `maxfeerate` is 0.1BTC, but pass if the default value is 0.1BTC/kB

0c62e3aa73839e97e65a3155e06a98d84b700a1e New regression testing for CVE-2018-17144, CVE-2012-2459, and CVE-2010-5137. (lucash-dev)

Pull request description:
This functional test includes two scenarios that test for regressions of vulnerabilities, but they are only briefly described. There are freely available documents explaining in detail the issues, but without explicit mentions, the developer trying to maintain the code needs an additional step of digging in commit history and PR conversations to figure it out.
Added comments to explicitly mention CVE-2018-17144 and CVE-2012-2459, for more complete documentation.
This improves developer experience by making understanding the tests easier.

Pull request description:
following situations are covered:
- empty block
- one Tx
- Merkle root of a block with odd Txs should not change with repeating
last one
- Merkle root is computed with combining Merkle root of left subtree and right subtree
- block witness is Merkle root of a block when setting first Tx
to zero.
