This is a simple change that makes our accept requirements the
same as our request requirements, (ever so slightly) further
decoupling our consensus logic from our FindNextBlocksToDownload
logic in net_processing.
Removes checking whitelisted behavior (which will be removed, the
difference in behavior here makes little sense) and no longer
requires that blocks at the same work as our tip be dropped if not
requested (in part because we *do* request those blocks).
e065249 Add unit test for outbound peer eviction (Suhas Daftuar)
5a6d00c Permit disconnection of outbound peers on bad/slow chains (Suhas Daftuar)
c60fd71 Disconnecting from bad outbound peers in IBD (Suhas Daftuar)
Pull request description:
The first commit will disconnect an outbound peer that serves us a headers chain with insufficient work while we're in IBD.
The second commit introduces a way to disconnect outbound peers whose chains fall out of sync with ours:
For a given outbound peer, we check whether their best known block (which is known from the blocks they announce to us) has at least as much work as our tip. If it doesn't, we set a 20 minute timeout, and if we still haven't heard about a block with as much work as our tip had when we set the timeout, then we send a single getheaders message, and wait 2 more minutes. If after two minutes their best known block has insufficient work, we disconnect that peer.
We protect 4 of our outbound peers (who provide some "good" headers chains, ie a chain with at least as much work as our tip at some point) from being subject to this logic, to prevent excessive network topology changes as a result of this algorithm, while still ensuring that we have a reasonable number of nodes not known to be on bogus chains.
We also don't require our peers to be on the same chain as us, to prevent accidental partitioning of the network in the event of a chain split. Note that if our peers are ever on a more work chain than our tip, then we will download and validate it, and then either reorg to it, or learn of a consensus incompatibility with that peer and disconnect. This PR is designed to protect against peers that are on a less work chain which we may never try to download and validate.

6d51eaefe qa: Fix race condition in sendheaders.py (Suhas Daftuar)
c96b2e4f0 qa: Fix replace-by-fee race condition failures (Suhas Daftuar)
Pull request description:
I think #11407 broke replace-by-fee by introducing a race condition. I was observing frequent failures of replace-by-fee locally, always with a mempool sync failure (the sync call was added in #11407).
It appeared to me like there were two causes: sometimes the node would be in IBD and not request the transaction that was relayed; other times the blocks generated in make_utxo wouldn't have relayed quickly enough for the spend of the transaction to be accepted. I believe I've fixed both potential errors.
ping @instagibbs
Edit: I found a race condition in the sendheaders.py test, where if the verack from the python node wasn't processed before the first block in the test was generated, then no block announcement would go out to that peer, breaking the test. Fixed by adding a sync_with_ping after waiting for verack.

Make sure wallet databases have unique fileids. If they don't, throw an error.
BDB caches do not work properly when more than one open database has the same
fileid, because values written to one database may show up in reads to other
databases.
Bitcoin will never create different databases with the same fileid, but users
can create them by manually copying database files.
BDB caching bug was reported by Chris Moore <dooglus@gmail.com>

eff4bd8 [test] P2P functional test for certain fingerprinting protections (Jim Posen)
a2be3b6 [net] Ignore getheaders requests for very old side blocks (Jim Posen)
Pull request description:
Sending a getheaders message with an empty locator and a stop hash is a request for a single header by hash. The node will respond with headers for blocks not in the main chain as well as those in the main chain. To avoid fingerprinting, the node should, however, ignore requests for headers on side branches that are too old. This replicates the logic that currently exists for `getdata` requests for blocks.

677d893ff [tests] do not allow assert_raises_message to be called with JSONRPCException (John Newbery)
5864e9c16 [tests] remove direct testing on JSONRPCException from individual test cases (John Newbery)
Pull request description:
I did this a few months ago (here: #9707), but a few new examples have crept back in.
When testing RPC failures, the test case should always assert the error value and message, to ensure that the failure was for the correct reason. Not doing that can hide bugs in the test code and mean that the test is not testing the correct behaviour.
RPC failure testing should use the utility function `assert_raises_jsonrpc()` (renamed in the final commit of this PR to `assert_raises_rpc_error()`.
This PR does the following:
- changes all remaining instances of tests directly testing on `JSONRPCException` to calls to `assert_raises_jsonrpc()`
- prevents `assert_raises_message()` from being called with `JSONRPCException`
- scripted-diff changes `assert_raises_jsonrpc()` to `assert_raises_rpc_error()`

Split off AuthServiceProxy.get_request method to make it easier to batch RPC
requests without duplicating code and remove leading underscore from _batch
method.
This does not change any existing behavior.
Change AuthServiceProxyWrapper.__getattr__ to only wrap proxied attributes, not
real attributes. This way AuthServiceProxyWrapper can continue logging RPC
calls without complicating other object usages, and special case handling for
the .url property can be dropped.

f97ab35fa qa: Fix bug introduced in p2p-segwit.py (Suhas Daftuar)
a7820422e qa: Treat mininode p2p exceptions as fatal (Suhas Daftuar)
Pull request description:
#11121 inadvertently broke the constructor for the `TestNode()` object in `p2p-segwit.py`, silently breaking at least one of the tests.
Although the python code was raising exceptions due to a `TestNode()` object not existing (or having the right type), mininode was masking these from anyone running the test through the test_runner (like travis), because it catches all exceptions during message delivery and just prints a log message and continues. Such "graceful" handling of errors is almost certainly something we don't want in our test suite, so the first commit here attempts to prevent that type of failure from ever being masked.
The second commit fixes the particular bug in `p2p-segwit.py`.
