463a1d5244 Refresh ZeroMQ 4.3.1 patch (Nathan Marley)
Pull request description:
Currently in Alpine Linux (latest, 3.10) in the depends system, one of the ZeroMQ patches won't apply cleanly because the context around the patch has changed and Alpine's `patch` implementation can't handle the diff.
Some patch implementations can't handle fuzz / too much divergence from the original code.
This PR just tweaks the context code around the patch so that less-sophisticated patch implementations (such as on Alpine Linux) can apply the patch without errors.
This partially fixes#16925

568aa0cf83 Add OpenSSL termios fix for musl libc (Nathan Marley)
Pull request description:
Currently the version of OpenSSL included in the depends system won't build on musl based systems because `termio.h` does not exist. The proper header named `termios.h` does exist.
This PR adds a patch for OpenSSL to replace the `termio.h` header with `termios.h`, which is the proper POSIX header as I understand it.
This is a known issue as `TERMIOS` (not `TERMIO`) should be the default, and is fixed in later versions of OpenSSL. There is discussion on the OpenSSL repo here: openssl/openssl#163
This has been [fixed in OpenSSL](64e6bf64b3).
This partly fixes#16925 and allows building Bitcoin on Alpine using the depends system.

67d99900b0 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.

efd2474d17 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.

fa607c2292 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).

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 is needed when some ports in the port range are used by other processes. Note that simply assigning the ports dynamically does not work:
* We spin up several nodes per test (each node gets its own port)
* We run several tests in parallel
