Currently difficulty adjustment violations are not reported for
chains that branch off before the last checkpoint. Change this
by moving the checkpoint check after the difficulty check.

While looking at the network code, we realized this code is unused and
largely unmaintained. Given issue #2231, and its removal in 1.21, it's
time to remove it now.
This has the nice benefit of removing a single point of failure/control
(because it depends on a keypair to send alerts).
This code restores the pre-alert behavior before the merge of PR #1470.
* Reduce DEFAULT_FALLBACK_FEE to 1,000,000 Koinu. Note this by itself has no effect as the required fee is higher.
* Reduce wallet minimum fees to 0.01 DOGE
* Update DEFAULT_DUST_LIMIT
* Revise derived values after updating recommended fees
* Remove fee rounding from RPC tests
* Revert tests back to Bitcoin originals where possible
Fix a rare crash bug where no best chain can be activated, and therefore when trying
to find the height of the best chain via the last block triggers a null pointer dereference.
Moves the break in ActivateBestChain() when a node is being shut
down from the beginning of the loop block to the end, allowing
pindexNewTip to be populated with chainActive.Tip() rather than
its initial NULL value. Solves issues when shutting down nodes
while inside the ActivateBestChain loop.
The call to CheckBlock() in ConnectBlock() is redundant with calls to it
prior to storing a block on disk. If CheckBlock() fails with an error
indicating the block is potentially corrupted, then shut down
immediately, as this is an indication that the node is experiencing
hardware issues. (If we didn't shut down, we could go into an infinite
loop trying to reconnect this same bad block, as we're not setting the
block's status to FAILED in the case where there is potential
corruption.)
If CheckBlock() fails for some other reason, we'll end up flagging this
block as bad (perhaps some prior software version "let a bad block in",
as the comment indicates), and not trying to connect it again, so this
case should be properly handled.
Checking scrypt PoW is expensive and needless in this case. All block
headers are already checked when they are accepted, and they will be
checked again on the receiving end.
Fix pruneheight help text.
Move fPruneMode block to match output ordering with help text.
Add functional tests for new fields in getblockchaininfo.
Rebase-from: bitcoin#b7dfc6c4
* Enable full block tests
* Fix invalidblocktest
* Move watch only address funding to immediately before it's used, so node 0 doesn't spend the output before it checks it later.
* Fix `fundrawtransaction` tests and sanitize fee calculation at the same time
* Correct resolution of chain parameters when validating tx inputs, especially from previous coinbase transactions
* Set block versions on full block tests so that the generated blocks are AuxPoW compatible
* Minimum number of blocks and blockchain size are increased for pruning. In comparison to Bitcoin this uses 24 hours as a minimum, rather than 48, although given blocks are rarely full this likely reflects a lot longer in reality.
* Multiply fork detection parameters by 5. The wall clock time elapsed for "long" forks is therefore half that of Bitcoin, but IMHO those figures are excessive for a chain with 1 minute block times.
* BIP16 and BIP30 have both been enabled on Dogecoin since inception and should not be conditional.
* Modify chain consensus parameters to be height aware
* Correct implementation of simplified rewards in parameters
* Correct max money
* Use base block version in IsSuperMajority() instead of full version
* Correct mining of blocks in AuxPoW tests
* Add in missing pre-AuxPoW consensus checks
Changes are as below:
Wrap CBlockHeader::nVersion into a new class (CBlockVersion). This allows to take care of interpreting the field into a base version, auxpow flag and the chain ID.
Update getauxblock.py for new 'generate' RPC call.
Add 'auxpow' to block JSON.
Accept auxpow as PoW verification.
Add unit tests for auxpow verification.
Add check for memory-layout of CBlockVersion.
Weaken auxpow chain ID checks for the testnet.
Allow Params() to overrule when to check the auxpow chain ID and for legacy blocks. Use this to disable the checks on testnet.
Introduce CPureBlockHeader.
Split the block header part that is used by auxpow and the "real" block header (that uses auxpow) to resolve the cyclic dependency between the two.
Differentiate between uint256 and arith_uint256.
This change was done upstream, modify the auxpow code.
Add missing lock in auxpow_tests.
Fix REST header check for auxpow headers.
Those can be longer, thus take that into account. Also perform the check actually on an auxpow header.
Correctly set the coinbase for getauxblock results.
Call IncrementExtraNonce in getauxblock so that the coinbase is actually initialised with the stuff it should be. (BIP30 block height and COINBASE_FLAGS.)
Implement getauxblock plus regression test.
Turn auxpow test into FIXTURE test.
This allows using of the Params() calls.
Move CMerkleTx code to auxpow.cpp.
Otherwise we get linker errors when building without wallet.
Fix rebase with BIP66.
Update the code to handle BIP66's nVersion=3.
Enforce that auxpow parent blocks have no auxpow block version.
This is for compatibility with namecoind. See also https://github.com/namecoin/namecoin/pull/199.
Move auxpow-related parameters to Consensus::Params.
* Replace chain parameters with Dogecoin values
* Update maximum coins to match Dogecoin
* Disable version 2 block requirement
* Update coinbase maturity to match Dogecoin
Always leave a reasonable buffer of 50MB for usage from newly connected block (once over 50%) and increase the high water mark buffer to 200MB.

Since we are more accurately measuring pcoinsTip peak usage at twice the current in dynamic usage, it makes sense to double the default (this will lead to the same effective usage and peak usage as previously).
We should also double the buffer used to avoid flushing if above 90% but still sufficient space remaining.

arguments, and restores a call to CheckBlock() from ProcessNewBlock()
as belt-and-suspenders.
