6b82fc59eb19004e54f910261a40d5e1b9e44b42 Use const in COutPoint class (Hennadii Stepanov)
Pull request description:
Refactoring:
- all cases of using `(uint32_t) -1` in `COutPoint` class are replaced with const;
- also all remaining instances of `(UNSIGNED)-1` transformed to `std::numeric_limits<UNSIGNED>::max()` (by @practicalswift).

172f5fa738 Support deserializing into temporaries (Pieter Wuille)
2761bca997 Merge READWRITEMANY into READWRITE (Pieter Wuille)
Pull request description:
This is another fragment of improvements from #10785.
The current serialization code does not support serializing/deserializing from/to temporaries (like `s >> CFlatData(script)`). As a result, there are many invocations of the `REF` macro which in addition to changing the reference type also changes the constness. This is unnecessary in C++11 as we can use rvalue references now instead.
The first commit is an extra simplification we can make that removes the duplication of code between `READWRITE` and `READWRITEMANY` (and related functions).

Pull request description:
This implements the compact block filter construction in [BIP 158](https://github.com/bitcoin/bips/blob/master/bip-0158.mediawiki). The code is not used anywhere in the Bitcoin Core code base yet. The next step towards [BIP 157](https://github.com/bitcoin/bips/blob/master/bip-0157.mediawiki) support would be to create an indexing module similar to `TxIndex` that constructs the basic and extended filters for each validated block.
### Filter Sizes
[Here](https://gateway.ipfs.io/ipfs/QmRqaAAQZ5ZX5eqxP7J2R1MzFrc2WDdKSWJEKtQzyawqog) is a CSV of filter sizes for blocks in the main chain.
As you can see below, the ratio of filter size to block size drops after the first ~150,000 blocks:
The reason for the relatively large filter sizes is that Golomb-coded sets only achieve good compression with a sufficient number of elements. Empirically, the average element size with 100 elements is 14% larger than with 10,000 elements.
The ratio of filter size to block size is computed without witness data for basic filters. Here is a summary table of filter size ratios *for blocks after height 150,000*:
| Stat | Filter Type |
|-------|--------------|
| Weighted Size Ratio Mean | 0.0198 |
| Size Ratio Mean | 0.0224 |
| Size Ratio Std Deviation | 0.0202 |
| Mean Element Size (bits) | 21.145 |
| Approx Theoretical Min Element Size (bits) | 21.025 |

* serialization: teach serializers variadics
Also add a variadic CDataStream ctor for ease-of-use.
* connman is in charge of pushing messages
The changes here are dense and subtle, but hopefully all is more explicit
than before.
- CConnman is now in charge of sending data rather than the nodes themselves.
This is necessary because many decisions need to be made with all nodes in
mind, and a model that requires the nodes calling up to their manager quickly
turns to spaghetti.
- The per-node-serializer (ssSend) has been replaced with a (quasi-)const
send-version. Since the send version for serialization can only change once
per connection, we now explicitly tag messages with INIT_PROTO_VERSION if
they are sent before the handshake. With this done, there's no need to lock
for access to nSendVersion.
Also, a new stream is used for each message, so there's no need to lock
during the serialization process.
- This takes care of accounting for optimistic sends, so the
nOptimisticBytesWritten hack can be removed.
- -dropmessagestest and -fuzzmessagestest have not been preserved, as I suspect
they haven't been used in years.
* net: switch all callers to connman for pushing messages
Drop all of the old stuff.
* drop the optimistic write counter hack
This is now handled properly in realtime.
* net: remove now-unused ssSend and Fuzz
* net: construct CNodeStates in place
* net: handle version push in InitializeNode
Adds an `obfuscate` parameter to `CLevelDBWrapper` and makes use of it
for all new chainstate stores built via `CCoinsViewDB`. Also adds an
`Xor` method to `CDataStream`.
Thanks to @sipa @laanwj @pstratem @dexX7 @KyrosKrane @gmaxwell.
This makes it easier for us to replace it if desired, since it's now only in
one spot. Also, it avoids the openssl include from allocators.h, which
essentially forced openssl to be included from every compilation unit.
