a92485b2c250fd18f55d22aa32722bf52ab32bfe addrman: use unordered_map instead of map (Vasil Dimov)
Pull request description:
`CAddrMan` uses `std::map` internally even though it does not require
that the map's elements are sorted. `std::map`'s access time is
`O(log(map size))`. `std::unordered_map` is more suitable as it has a
`O(1)` access time.
This patch lowers the execution times of `CAddrMan`'s methods as follows
(as per `src/bench/addrman.cpp`):
```
AddrMan::Add(): -3.5%
AddrMan::GetAddr(): -76%
AddrMan::Good(): -0.38%
AddrMan::Select(): -45%
```

Pull request description:
When writing tests, often includes need to be added or removed. Currently the list of includes is not sorted, so developers that write tests and have `clang-format` installed will either have an unrelated change (sorting) included in their commit or they will have to manually undo the sort.
This pull preempts both issues by just sorting all includes in one commit.
Please be aware that this is **NOT** a change to policy to enforce clang-format or any other developer guideline or process. Developers are free to use whatever tool they want, see also #18651.
Edit: Also includes a commit to bump the copyright headers, so that the touched files don't need to be touched again for that.

Make reasoning about dependencies easier by not including unused dependencies.
Please note that the removed headers are _not_ "transitively included" by other still included headers. Thus the removals are real.
As an added bonus this change means less work for the preprocessor/compiler. At least 51 393 lines of code no longer needs to be processed:
```
$ git diff -u HEAD~1 | grep -E '^\-#include ' | cut -f2 -d"<" | cut -f1 -d">" | \
sed 's%^%src/%g' | xargs cat | wc -l
51393
```
Note that 51 393 is the lower bound: the real number is likely much higher when taking into account transitively included headers :-)

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).

Pull request description:
This improves a few minor issues with the RNG code:
* Avoid calling `GetRand*()` functions (which currently invoke OpenSSL, later may switch to using our own RNG pool) inside loops in addrman, networking code, `KnapsackSolver`, and `LimitOrphanSize`
* Fix a currently unreachable bug in `FastRandomContext::randbytes`.
* Make a number of simplifications to the unit tests' randomness code (some tests unnecessarily used their own RNG or the OpenSSL one, instead of using the unit test specific `insecure_rand_ctx`).
* As a precaution, make it illegal to copy a `FastRandomContext`.

4d834018e368c3481a5421891395f64aa9002185 [addrman] Improve tried table collision logging (Suhas Daftuar)
Pull request description:
The restriction on outbound peers sharing the same network group is not intended to apply to feeler connections, so fix this.
This fixes an issue where a tried table collision with an entry to a netgroup we already have an outbound connection to could cause feelers to stop working, because the tried collision buffer (`m_tried_collisions`) would never be drained.
Also, ensure that all entries don't linger in `m_tried_collisions` by evicting an old entry if its collisions is unresolved after 40 minutes.

e68172ed9 Add test-before-evict discipline to addrman (Ethan Heilman)
Pull request description:
This change implement countermeasures 3 (test-before-evict) suggested in our paper: ["Eclipse Attacks on Bitcoin’s Peer-to-Peer Network"](http://cs-people.bu.edu/heilman/eclipse/).
# Design:
A collision occurs when an address, addr1, is being moved to the tried table from the new table, but maps to a position in the tried table which already contains an address (addr2). The current behavior is that addr1 would evict addr2 from the tried table.
This change ensures that during a collision, addr1 is not inserted into tried but instead inserted into a buffer (setTriedCollisions). The to-be-evicted address, addr2, is then tested by [a feeler connection](https://github.com/bitcoin/bitcoin/pull/8282). If addr2 is found to be online, we remove addr1 from the buffer and addr2 is not evicted, on the other hand if addr2 is found be offline it is replaced by addr1.
An additional small advantage of this change is that, as no more than ten addresses can be in the test buffer at once, and addresses are only cleared one at a time from the test buffer (at 2 minute intervals), thus an attacker is forced to wait at least two minutes to insert a new address into tried after filling up the test buffer. This rate limits an attacker attempting to launch an eclipse attack.
# Risk mitigation:
- To prevent this functionality from being used as a DoS vector, we limit the number of addresses which are to be tested to ten. If we have more than ten addresses to test, we drop new addresses being added to tried if they would evict an address. Since the feeler thread only creates one new connection every 2 minutes the additional network overhead is limited.
- An address in tried gains immunity from tests for 4 hours after it has been tested or successfully connected to.
# Tests:
This change includes additional addrman unittests which test this behavior.
I ran an instance of this change with a much smaller tried table (2 buckets of 64 addresses) so that collisions were much more likely and observed evictions.

# Security Benefit
This is was originally posted in PR #8282 see [this comment for full details](https://github.com/bitcoin/bitcoin/pull/8282#issuecomment-237255215).
To determine the security benefit of these larger numbers of IPs in the tried table I modeled the attack presented in [Eclipse Attacks on Bitcoin’s Peer-to-Peer Network](https://eprint.iacr.org/2015/263).
**Default node:** 595 attacker IPs for ~50% attack success.
**Default node + test-before-evict:** 620 attacker IPs for ~50% attack success.
**Feeler node:** 5540 attacker IPs for ~50% attack success.
**Feeler node + test-before-evict:** 8600 attacker IPs for ~50% attack success.
The node running feeler connections has 10 times as many online IP addresses in its tried table making an attack 10 times harder (i.e. requiring the an attacker require 10 times as many IP addresses in different /16s). Adding test-before-evict increases resistance of the node by an additional 3000 attacker IP addresses.
Below I graph the attack over even greater attacker resources (i.e. more attacker controled IP addresses). Note that test-before-evict maintains some security far longer even against an attacker with 50,000 IPs. If this node had a larger tried table test-before-evict could greatly boost a nodes resistance to eclipse attacks.

* Fix BENCH and RAND conflicts
* Add ALERT and use it
* Update LogPrint-s in dash-specific code
* Tweak few log categories
Specifically:
- use PRIVATESEND in `CPrivateSendClientManager::GetRandomNotUsedMasternode()`
- use ZMQ in `CZMQPublishRawGovernanceVoteNotifier::NotifyGovernanceVote()` and `CZMQPublishRawGovernanceObjectNotifier::NotifyGovernanceObject()`

* Shift dash-specific log categories to start from `1ul << 32` to avoid potential future conflicts with bitcoin ones
* Fix `dash` category
* remove debugCategories
Signed-off-by: Pasta <Pasta@dash.org>
* Prepend "std::" to find call
* Check for BCLog::PRIVATESEND instead of logCategories != BCLog::NONE
* Use BCLog::MNPAYMENTS category instead of checking for logCategories != BCLog::NONE
* Move "End Dash" comment below "ALERT"
When adding new entries here, we'll otherwise get confused with ordering
and might end up forgetting that adding something Dash specific must
continue with the bit after 43.
* Remove testnet seeds from devnet
* Lift multiple ports restriction on devnet when considering new nodes
Allow to connect to multiple nodes behind the same IP
* Don't skip addresses with non-default port if it matches -port
If the user specified -port, he very likely intends to connect to nodes
with the same port.
* Don't pass false to CAddrMan constructor as it is already the default
* Make if statements easier to read
6182d10 Do not increment nAttempts by more than one for every Good connection. (Gregory Maxwell)
c769c4a Avoid counting failed connect attempts when probably offline. (Gregory Maxwell)
* Only store and connect to NODE_NETWORK nodes
* Keep addrman's nService bits consistent with outbound observations
* Verify that outbound connections have expected services
* Don't require services in -addnode
* Introduce enum ServiceFlags for service flags
* Introduce REQUIRED_SERVICES constant
Adds several unittests for CAddrMan and CAddrInfo.
Increases the accuracy of addrman tests.
Removes non-determinism in tests by overriding the random number generator.
Extracts testing code from addrman class to test class.
On hosts that had spent some time with a failed internet connection their
nAttempts penalty was going through the roof (e.g. thousands for all peers)
and as a result the connect search was pegging the CPU and failing to get
more than a 4 connections after days of running (because it was taking so
long per try).
