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).

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.

Pull request description:
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.

Pull request description:
# Introduction
As discussed with @laanwj on IRC:
- PID file creation was never enabled for Windows, as the `pid_t` filetype is not available for it. However, the WIN32 API contains the header [`Processthreadsapi.h`](https://github.com/CodeShark/x86_64-w64-mingw32/blob/master/include/processthreadsapi.h) which in turn contains the function [`GetCurrentProcessId()`](https://docs.microsoft.com/en-gb/windows/desktop/api/processthreadsapi/nf-processthreadsapi-getcurrentprocessid). ~~This function is called at a higher level by [`_getpid()`](https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/getpid?view=vs-2017)~~ EDIT: `_getpid()` is not available to the MSVC compiler used in the AppVeyor build. As a result, I have changed the function call to`GetCurrentProcessId()`, which performs the same function and is available to both MinGW & MSVC.
This allows one to capture the PID in Windows, without any additional includes - the above function is already available.
- Within this PR, I have added a separate line that calls `GetCurrentProcessId()` in the case of a WIN compilation, and the usual `getpid()` otherwise. All code blocks processing PID file logic that avoid WIN32 have been changed to consider it. I have also updated the preprocessor definitions in `libbitcoin_server.vcxproj.in` to suppress a warning related to `std::strerror` for the MSVC build, that was causing the AppVeyor build to fail (see @fanquake comment below).
# Rationale
- Consistency between OS's running Bitcoin
- Applications which build off of `bitcoind`, such as novel front-end clients, often need access to the PID in order to control the daemon. Instead of designing some alternate way of doing this for one system, it should be consistent between all of them.

**Notes for reviewers**
1. `CreatePidFile()` has been moved from `util/system.cpp` to `init.cpp` for the following reasons:
- to get the ability to use `InitError()`
- now `init.cpp` contains code of both creating PID file and removing it
2. Regarding 0.18 release process: this PR modifies 1 string and introduces 2 new ones.

This commit attempts to clarify and correct the `-blocksdir` argument
description and default value. `-blocksdir` does not refer to the full
path to the actual `blocks` directory, but rather the root/parent
directory which contains the `blocks` directory. Accordingly, the
default value is `<datadir>` and not `<datadir>/blocks`. It also
attempts to clarify that only the `.dat` files containing block data are
impacted by `-blocksdir`, not the index files.

Also this prevents the side effect of calling `GetBlocksDir(false)` in the non-mainnet environment.
Currently a new node creates an unused `blocks\` directory in the root of the data directory when `-testnet` or `-regtest` is specified.

Currently the `unloadwallet` RPC is asynchronous, it only signals the intent to unload the wallet and then returns the response to the client. The actual unload can happen later and the client has no way to be notified of that.

48b37db50 make peertimeout a debug argument, remove error message translation (Zain Iqbal Allarakhia)
8042bbfbf p2p: allow p2ptimeout to be configurable, speed up slow test (Zain Iqbal Allarakhia)
Pull request description:
**Summary:**
1. _Primary_: Adds a `debug_only=true` flag for peertimeout, defaults to 60 sec., the current hard-coded setting.
2. _Secondary_: Drastically speeds up `p2p_timeout.py` test.
3. _Secondary_: Tests that the correct code path is being tested by adding log assertions to the test.
**Rationale:**
- P2P timeout was hard-coded: make it explicitly specified and configurable, instead of a magic number.
- Addresses #13518; `p2p_timeout.py` takes 4 sec. to run instead of 61 sec.
- Makes `p2p_timeout.py` more explicit. Previously, we relied on a comment to inform us of the timeout amount being tested. Now it is specified directly in the test via passing in the new arg; `-peertimeout=3`.
- Opens us up to testing more P2P scenarios; oftentimes slow tests are the reason we don't test.
