4d834018e3 [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.

32da92bdf6 gitian: Improve error handling (Wladimir J. van der Laan)
Pull request description:
Improve error handling in gitian builds:
- Set fail-on-error and pipefail flag, this causes a command to fail when either of the pipe stages fails, not only when the last of the stages fails, so this improves error detection.
- Also use `xargs` instead of `find -exec`, because `find` will not propagate errors in the executed command, but `xargs` will.
This will avoid some issues like #15541 where non-determinism is silently introduced due to errors caused by environment conditions (such as lack of disk space in that case).

9d6dcc52c6 Abstract EraseBlockData out of RewindBlockIndex (Pieter Wuille)
Pull request description:
This PR makes a number of improvements to the InvalidateBlock (`invalidateblock` RPC) and RewindBlockIndex functions, primarily around breaking up their long-term cs_main holding. In addition:
* They're made safely interruptible (`bitcoind` can be shutdown, and no progress in either will be lost, though if incomplete, `invalidateblock` won't continue after restart and will need to be called again)
* The validation queue is prevented from overflowing (meaning `invalidateblock` on a very old block will not drive bitcoind OOM) (see #14289).
* `invalidateblock` won't bother to move transactions back into the mempool after 10 blocks (optimization).
This is not an optimal solution, as we're relying on the scheduler call sites to make sure the scheduler doesn't overflow. Ideally, the scheduler would guarantee this directly, but that needs a few further changes (moving the signal emissions out of cs_main) to prevent deadlocks.
I have manually tested the `invalidateblock` changes (including interrupting, and running with -checkblockindex and -checkmempool), but haven't tried the rewinding (which is probably becoming increasingly unnecessary, as very few pre-0.13.1 nodes remain that would care to upgrade).

Link against BasicTestingSetup in the fuzz tests, so we can fuzz against validation.
Also include a commit to remove test_bitcoin_main.cpp. That file may or may not overwrite globals in the link stage depending on the link order. This is confusing and useless anyway: The unit tests should never `std::exit` in the middle of the run (especially with success as exit code), since it will skip all test modules afterward.
Also include a commit to remove some unused forward declarations and move the main_tests to validation_tests, since main was long ago split into net_processing and validation.

Pull request description:
Python 3.4 is EOL after March 2019, so switch to 3.5. See https://devguide.python.org/#status-of-python-branches
This pull does the following in a bunch of commits:
* scripted diff to use the `bytes::hex()` method in place of previous wrappers (`b2x`, `bytes_to_hex_str`, `hexlify`, ...)
* Update the build system (gitian and travis) to remove python2.7 and replace it with python3.5
* Another scripted-diff to remove brackets after `assert`. This is unrelated to the python3.5 switch, but a stylistic commit, so probably not worth to split up. The motivation behind it is to avoid asserting on data structures (such as tuples of length one), which never fails:
```py
>>> assert(False,) # with brackets
>>> assert False, # without brackets
SyntaxError: invalid syntax
>>> assert False # proper assertion
AssertionError
```
* And then a final scripted diff to update the copyright headers in the `test` subfolder, since I touched most of the files anyway and it wouldn't make sense to split this commit out into a separate pull.

> Most bitcoin.conf options apply to all three networks,
however some apply only to mainnet unless specified in a section.
As stands, conf file has no indication that sections are now in use
or are in some circumstances mandatory (eg, changing rpcport for testnet.)
> Proposed change notifies the reader early which options are affected,
specifically adds those options affected but not already in the example,
adds brief explanation as to what's going on and provides a skeleton template for the sections themselves.

This change removes wallet calls to node functions that access global chain and mempool state.
This is the next step in the larger #10973 refactoring change, which removes all other accesses to node global variables from wallet code. Doing this is useful to provide a better defined interface between the wallet and node, and necessary to allow wallet and node code to run in separate processes in #10102.

Pull request description:
This cleans up and refactors block file helpers so that they may be used by the block filter indexer. Per [design discussion](https://github.com/bitcoin/bitcoin/pull/14121#issuecomment-451252591) about storing BIP 157 block filters, it has been suggested that they are stored in the same way as block and undo data. This refactor is sufficient to simplify file operations for this use case, though in the future perhaps more pruning-related logic ought to be moved into the new classes.
The basic abstraction is a `FlatFileSeq` which manages access to a sequence of numbered files into which raw data is written.

In #14708, It was introduced that to warn when unrecognized section names are exist in the config file.
But ```m_config_sections.clear()``` in ```ArgsManager::ReadConfigStream()``` is called every time when reading each configuration file, so it can warn about only last reading file if ```includeconf``` exists.
This PR fix lack of warning by collecting all section names by moving ```m_config_sections.clear()``` to ```ArgsManager::ReadConfigFiles()``` .
Also add a test code to confirm this situation.
