Changes the logic to only request from up to 4 peers, and to prefer masternodes for these peers. In practice, even if these four nodes do not forward the transaction, it doesn't matter, and we will receive the tx soon via inv
* refactor: break circular dependencies(-13, +2)
introduces specialtxman, which handles validation of special transactions, specialtx is now simply the primitive underlying type. This breaks a lot of the circular depends
Also removes an unneeded `#include <masternode/payments.h>` in net_processing.cpp, which resolves a circular dependency. (we know it's okay to remove b/c masternode/payments.h isn't included in any header files, and removing it doesn't break compilation)
* format: make clang-format happy
* remove unrelated change
* remove some unneeded includes to `evo/deterministicmns.h`, explicitly include some previously implicitly included includes.
Resolves two circular dependencies
* refactor: remove circular depend, unused include

* refactor: use a vector instead of map for llmqs
this is a valuable refactor for a number of reasons.
it forces the removal of more verbose `Params().GetConsensus().llmqs.count` and instead call to `Params().HasLLMQ()`
`llmqs` is now stored in contiguous memory (which hopefully means better lookup time / iteration time)
std::vector is much more constexpr friendly, and normally is better optimized

* refactor: numerous changes to avoid passing around a const ref to shared_ptr of CDeterministicMNC when not needed.
Introduces ForEachMNShared, a version of ForEachMN that uses a shared_ptr, and may extend the lifetime of the underlying shared_ptr. This is not preferred, should prefer ForEachMN. See docs.
Adjusts ForEachMN to pass a reference. This is preferred for use over ForEachMNShared. See docs. A reference should be used since in usage we assume it's non-null anyway. Additionally, it allows us to know that the lifespan of the dmn is not being being extended (if lifespan needs to be extended, should use ForEachMNShared.
IsMNValid, IsMNPoSeBanned, UpdateMN, UpdateMN, AddUniqueProperty, DeleteUniqueProperty, UpdateUniqueProperty now take a const reference to CDeterministicMN instead of a const reference to shared_ptr<CDeterministicMN>. All of these functions previously assumed (or would've crashed) a non-null ptr, and non extended lifetime, as such converting to ref is appropriate.
CompareByLastPaid ptr overload now takes raw ptr instead of a const ref to shared. Since we simply dereference them, a raw ptr makes the most sense. This also avoids a potential expensive and implicit raw ptr -> shared ptr conversion if the function was called with raw ptrs.
rpcevo BuildDMNListEntry now takes a const ref for reasons as stated above

Pull request description:
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 :-)

fab0c820fa4c0c3227eec85c64310a3bf938a149 rpc: Clarify that block count means height excl genesis (MarcoFalke)
Pull request description:
There is a common misconception that the block count returned by the blockchain rpcs includes the genesis block. See for example the discussion in https://github.com/bitcoin/bitcoin/pull/16292#issuecomment-506303256.
However, it really returns the height, which is `0` for the genesis block.
So clarify that and also remove the misleading "longest blockchain" comment.
Finally, fix the wallet test that incorrectly used this rpc.

787df19b09babf50dd8124b3ac990b29c33cfe93 validation: don't try to invalidate genesis block (Sebastian Falbesoner)
Pull request description:
In the block invalidation method (`CChainState::InvalidateBlock`), the code for creating the candidate block map assumes that the passed block's previous block (`pindex->pprev`) is available and otherwise segfaults due to null-pointer deference in `CBlockIndexWorkComparator()` (see analysis by practicalswift in #20914), i.e. it doesn't work with the genesis block. Rather than analyzing all possible code paths and implications for this corner case, simply fail early if the genesis block is passed.
Fixes#20914.

850847309458f43fc7ce6c13fa08c86e1cae042a Avoid non-trivial global constants in SHA-NI code (Pieter Wuille)
Pull request description:
This is a potential solution for #18456.
It seems that the compiler cannot turn `_mm_set_epi64x(<constant>,<constnant>)` into a constant itself, and thus emits a global initializer for the `MASK`, `INIT0`, and `INIT1` global constants in the sha-ni SHA256 implementation.
Change this by turning them into dumb byte arrays, loading them into an SSE variable whenever needed.
Tested on a SHA-NI capable machine. I do not observe any obvious performance impact (but this is hard to measure, it's already very fast...).

Pull request description:
This pull fixes the example curl command for `getblockstats` which doesn't work as is because it's missing a comma between the params and has single quotes around the second parameter.
It also adds an additional example of getting block stats by hash by using a known workaround (#15412) to get bitcoin-cli to treat the hash parameter as JSON instead of a string since there is ongoing deliberation about how or whether to fix the root issue (#15448).

ef35604c9c88e7800e9be106b791b1c0fa8b310a rpc: fix broken RPCExamples for waitforblock(height) (Sebastian Falbesoner)
Pull request description:
This PR fixes several broken RPCExamples from the "blockchain" category:
- `HelpExampleCli` for `waitforblock` (disturbing comma between arguments)
- `HelpExampleCli` for `waitforblockheight` (disturbing comma between arguments)
- `HelpExampleRpc` for `waitforblockheight` (disturbing quotation marks around integer argument)
Note that the CLI example for `waitforblockheight` would also work with the first argument in quotation marks (in contrast to the RPC example), but I removed them as well as they are not needed.

7d0a8f4f530885cbf3870291f10f667326373bd1 refactor: Remove never used default parameter (Hennadii Stepanov)
Pull request description:
In `BitcoinGUI::message()` slot the `bool* ret = nullptr` parameter is never used.
This PR removes it and simplifies connections syntax by replacing lambdas with the `&BitcoinGUI::message` slot.

7d263571bee8c36fbe3c854b69c6f31cf1ee3b9b rpc: require second argument only for scantxoutset start action (Andrew Chow)
Pull request description:
It was reported on [IRC](http://www.erisian.com.au/bitcoin-core-dev/log-2019-12-11.html#l-377) that `scantxoutset`'s API was broken in 0.19.0:
```
<belcher> i think scantxoutset may have been broken in bitcoin core 0.19 ? regardless of what parameters i run it with (e.g. "scantxoutset abort", "scantxoutset status") it just returns the help doc, according to the release notes the only change was https://github.com/bitcoin/bitcoin/pull/16285/files but i dont see anything that wouldve broken it, it works fine in 0.18
<belcher> im on regtest, in case its important
<harding> I can confirm `scantxoutset abort` returns the help doc on latest master. Waiting for 0.18.1 to start now to attempt to reproduce there.
<harding> It looks like it's expecting a second parameter (even though that doesn't make sense with "abort").
<jonatack> Same for me as well
<harding> Can also confirm that `scantxoutset abort` returns the expected result on 0.18.1.
```
As noted in the conversation, previously, the second argument of `scanobjects` is only required for the `start` action. `Stop` and `abort` actions did not and could work without them.
It appears that this was broken by #16240 which enforced the size of the arguments to match the listed required arguments.
To fix this issue, this PR makes the `scanobjects` argument an optional argument. Then only in the `start` action do we check whether the `scanobjects` argument is there and throw an informative error about that. Also a test is added for this case.
