Pull request description:

  It looks like `doc/tor.md` could use some updates and improvements, not only for Tor v3, but also for setting multiple addresses with `-externalip` (see the conversation from http://www.erisian.com.au/bitcoin-core-dev/log-2020-09-16.html#l-39), how to see information about your Tor config via Bitcoin Core, and other improvements.

  Closes #19924.

Merge #19050: doc: Add warning for rest interface limitation
5c3eaf9983 doc: Add warnings for http interfaces limitations (Fabian Jahr)

Pull request description:

  `libevent`, which is used for our rest interface, can use up all of the available file descriptors in a system if too many connections are opened at once. If a new block is connected at the same time and can not be written to disk because there are no file descriptors available, the node crashes. Based on my investigation so far the issue is best solved upstream which means we have to wait for the next release (2.2). In the meantime it would be good if we would warn users of this limitation.

  See #11368 for more background.

c175690561 doc: Update for FreeBSD 12.2, add GUI Build Instructions (Jarol Rodriguez)

Merge #20560: fuzz: Link all targets once
fa13e1b0c5 build: Add option --enable-danger-fuzz-link-all (MarcoFalke)
44444ba759 fuzz: Link all targets once (MarcoFalke)

Pull request description:

  Currently the linker is invoked more than 150 times when compiling with `--enable-fuzz`. This is problematic for several reasons:

  * It wastes disk space north of 20 GB, as all libraries and sanitizers are linked more than 150 times
  * It wastes CPU time, as the link step can practically not be cached (similar to ccache for object files)
  * It makes it a blocker to compile the fuzz tests by default for non-fuzz builds #19388, for the aforementioned reasons
  * The build file is several thousand lines of code, without doing anything meaningful except listing each fuzz target in a highly verbose manner
  * It makes writing new fuzz tests unnecessarily hard, as build system knowledge is required; Compare that to boost unit tests, which can be added by simply editing an existing cpp file
  * It encourages fuzz tests that re-use the `buffer` or assume the `buffer` to be concatenations of seeds, which increases complexity of seeds and complexity for the fuzz engine to explore; Thus reducing the effectiveness of the affected fuzz targets

  Fixes #20088

doc: Update for FreeBSD 12.2, add GUI Build Instructions
The current FreeBSD Build documentation is a little outdated and underwhelming. This PR updates the doc to
be more informative. It also adds new instructions for building the GUI and adding support for  descriptor
wallets.

on vasild's recommendation: it is ok to point the user to download db5 which has an active port package
instead of building db4 from the provided script.

a7ed00f8bb rpc: expose high-bandwidth mode states via getpeerinfo (Sebastian Falbesoner)
30bc8fab68 net: save high-bandwidth mode states in CNodeStats (Sebastian Falbesoner)

Pull request description:

  Fixes #19676, "_For every peer expose through getpeerinfo RPC whether or not we selected them as HB peers, and whether or not they selected us as HB peers._" See [BIP152](https://github.com/bitcoin/bips/blob/master/bip-0152.mediawiki), in particular the [protocol flow diagram](https://github.com/bitcoin/bips/raw/master/bip-0152/protocol-flow.png).  The newly introduced states are changed on the following places in the code:
  * on reception of a `SENDCMPCT` message with valid version, the field `m_highbandwidth_from` is changed depending on the first integer parameter in the message (1=high bandwidth, 0=low bandwidth), i.e. it just mirrors the field `CNodeState.fPreferHeaderAndIDs`.
  * after adding a `SENDCMPCT` message to the send queue, the field `m_highbandwidth_to` is changed depending on how the first integer parameter is set (same as above)

  Note that after receiving `VERACK`, the node also sends `SENDCMPCT`, but that is only to announce the preferred version and never selects high-bandwidth mode, hence there is no need to change the state variables there, which are initialized to `false` anyways.

Pull request description:

  This is a requirement for C++17 support. See my comments [here](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-643722538):

  > You cannot use std::get with std::variant on macOS < 10.14, because Apples libc++ doesn't support the std::bad_variant_access exception. [Relevant comment](https://github.com/bitcoin/bitcoin/pull/19183#discussion_r439794318) in #19183.

  > While we could work around this in our own code, using std::get_if, this would still be a problem for 3rd-party dependencies.

  > I've been testing Qt 5.15LTS (we'll have to enable C++17 in qt, and may upgrade to a newer version at the same time), and you can't enable -std c++17, while targeting a macOS deployment version < 10.14, configuring will fail. They are making use of std::get with std::variant throughout their cocoa code.

  We would have to had to have bumped to at least 10.13 in any case, as Qt 5.15 (#19716) [requires 10.13+](https://doc.qt.io/qt-5/supported-platforms.html).

Merge #20223: build: Drop the leading 0 from the version number
8f7b930475 Drop the leading 0 from the version number (Andrew Chow)

Pull request description:

  Removes the leading 0 from the version number. The minor version, which we had been using as the major version, is now the major version. The revision, which we had been using as the minor version, is now the minor version. The revision number is dropped. The build number is promoted to being part of the version number. This also avoids issues where it was accidentally not included in the version number.

  The CLIENT_VERSION remains the same format as previous as previously, as the Major version was 0 so it never actually got included in it.

  The user agent string formatter is updated to follow this new versioning.

  ***

  Honestly I'm just tired of all of the people asking for "1.0" that maybe this'll shut them up. Skip the whole 1.0 thing and go straight to version 22.0!

  Also, this means that the terminology we commonly use lines up with how the variables are named. So major versions are actually bumping the major version number, etc.

dc80a7d0b0 docs/descriptors.md: Remove hardened marker in the path after xpub (Dmitry Petukhov)

Pull request description:

  As described in "Key origin identification" section, a descriptor
  that has hardened derivation after xpub does not let you compute scripts
  without access to the corresponding private keys. Such a descriptor is
  practically useless.

  The text after the descriptor said "with child key *1'/2* of the
  specified xpub", and clearly an xpub cannot have "child key" with
  hardened derivation. Therefore it makes sense to fix this inconsistency
  to not confuse the reader of the doc

accidentally not included in the version number.

The CLIENT_VERSION remains the same format as previous as previously,
the Major version was 0 so that was never a factor in CLIENT_VERSION.

Merge #20414: doc: Remove generated manual pages from master branch
daf1ebf0b1 doc: Remove generated manual pages from master branch (Wladimir J. van der Laan)

Pull request description:

  Replace the generated manual pages on the master branch with placeholders with instructions. The master branch is too much in flux for anything generated from command output to be kept up to date, and having pages from versions ago looks silly.

  We can't remove them completely because `make dist` relies on the files being present.

  Resolves #20062.

Merge #19504: Bump minimum python version to 3.6
97c738ff1b [tests] Recommend f-strings for formatting, update feature_block to use them (Anthony Towns)
8ae9d314e9 Bump minimum python version to 3.6 (Anthony Towns)

Pull request description:

  Python 3.5 has reached [end-of-life](https://devguide.python.org/#status-of-python-branches) as of September 2020, and 3.6 has some moderately nice [features](https://docs.python.org/3/whatsnew/3.6.html):

  - `f'x = {x}'` as an alternative to `'x = {}'.format(x)` format strings (cf https://github.com/bitcoin/bitcoin/pull/13718#issuecomment-406591027)
  - underscore separators for large numbers, like `1_234_567`
  - improvements to async
  - improvements to typing module

  Note that 3.6 is not available in xenial (16.04), but is available in bionic (18.04), while focal (20.04) has 3.8. CentOS 7 and 8 have 3.6.8, Debian stable has 3.7.3, and [gentoo and arch already had 3.6 and 3.7 in 2018](https://github.com/bitcoin/bitcoin/pull/14954#issuecomment-447118707).

Merge #20284: addrman: ensure old versions don't parse peers.dat
38ada892ed addrman: ensure old versions don't parse peers.dat (Vasil Dimov)

Pull request description:

  Even though the format of `peers.dat` was changed in a backwards
  incompatible way, it is not guaranteed that old versions will fail to
  parse it. There is a chance that old versions parse its contents as
  garbage and use it.

  Old versions expect the "key size" field to be 32 and fail the parsing
  if it is not. Thus, we put something other than 32 in it. This will make
  versions between 0.11.0 and 0.20.1 deterministically fail on the new
  format. Versions prior to https://github.com/bitcoin/bitcoin/pull/5941
  will still parse it as garbage.

  Also, introduce a way to increment the `peers.dat` format in a way that
  does not necessary make older versions refuse to read it.

docs/descriptors.md: Remove hardened marker in the path after xpub
As described in "Key origin identification" section, a descriptor
that has hardened derivation after xpub does not let you compute scripts
without access to the corresponding private keys. Such a descriptor is
practically useless.

The text after the descriptor said "with child key *1'/2* of the
specified xpub", and clearly an xpub cannot have "child key" with
hardened derivation. Therefore it makes sense to fix this inconsistency
to not confuse the reader of the doc

Merge #20186: wallet: Make -wallet setting not create wallets
01476a88a6 wallet: Make -wallet setting not create wallets (Russell Yanofsky)

Pull request description:

  This changes `-wallet` setting to only load existing wallets, not create new ones.

  - Fixes settings.json corner cases reported by sjors & promag: https://github.com/bitcoin-core/gui/issues/95, https://github.com/bitcoin/bitcoin/pull/19754#issuecomment-685858578, https://github.com/bitcoin/bitcoin/pull/19754#issuecomment-685858578

  - Prevents accidental creation of wallets reported most recently by jb55 http://www.erisian.com.au/bitcoin-core-dev/log-2020-09-14.html#l-355

  - Simplifies behavior after #15454. #15454 took the big step of disabling creation of the default wallet. This PR extends it to avoid creating other wallets as well. With this change, new wallets just aren't created on startup, instead of sometimes being created, sometimes not. #15454 release notes are updated here and are simpler.

  This change should be targeted for 0.21.0. It's a bug fix and simplifies behavior of the #15937 / #19754 / #15454 features added in 0.21.0.

  This PR is implementing the simplest, most basic alternative listed in https://github.com/bitcoin-core/gui/issues/95#issuecomment-694236940. Other improvements mentioned there can build on top of this.
