* build: Fix `--enable-glibc-back-compat`
Compiling on Ubuntu 20.04 results in binaries that can't be run on older systems we still support (e.g. Ubuntu 16.04) and `contrib/devtools/symbol-check.py` complains about it.
Available versions for `log` for example:
$ objdump -T /lib/x86_64-linux-gnu/libm.so.6 | egrep -w 'log'
00000000000431b0 g DF .text 0000000000000039 GLIBC_2.29 log
0000000000012360 g DF .text 0000000000000066 (GLIBC_2.2.5) log
(i.e. the default one is 2.29)
This commit fixes the issue by picking the version we support instead of the default one.
Before:
$ objdump -T dashd | egrep -w 'log'
0000000000000000 DF *UND* 0000000000000000 GLIBC_2.29 log
After:
$ objdump -T dashd | egrep -w 'log'
0000000000000000 DF *UND* 0000000000000000 GLIBC_2.2.5 log
* ci: Add `make check-symbols` to the `build` step
* ci: Do not specify `--enable-glibc-back-compat` for non-release builds
* ci: Set correct LDFLAGS for the release build
* doc: Update docs to mention the need for `LDFLAGS=-static-libstdc++` when compiling for same host but different distro
* ci: Add `--with-sanitizers=undefined` back to `linux64` build

I placed it between i686 and x86_64 since it looked like the original list of Linux arches was in alphabetical order; I'm open to including it in a different position if the desire is to keep the two ARM arches together and the two x86 arches together.

* homogenous is present in tinyformat, hence should be addressed upstream

While reading the build docs, I found some opportunities for textual improvements (Force of habit, I used to work as a technical writer...)
* Added a few missing words, should be uncontroversial.
* Changed/added some punctuation, for better flow and readability.
* Fixed one Markdown issue, where two list item headings rendered without a line break. (See image)
This one needs to be verified after a build, I don't have a proper build environment yet.

c276df775914e4e42993c76e172ef159e3b830d4 zmq: enable tcp keepalive (mruddy)
Pull request description:
This addresses https://github.com/bitcoin/bitcoin/issues/12754.
These changes enable node operators to address the silent dropping (by network middle boxes) of long-lived low-activity ZMQ TCP connections via further operating system level TCP keepalive configuration. For example, ZMQ sockets that publish block hashes can be affected in this way due to the length of time it sometimes takes between finding blocks (e.g.- sometimes more than an hour).
Prior to this patch, operating system level TCP keepalive configurations would not take effect since the SO_KEEPALIVE option was not enabled on the underlying socket.
There are additional ZMQ socket options related to TCP keepalive that can be set. However, I decided not to implement those options in this changeset because doing so would require adding additional bitcoin node configuration options, and would not yield a better outcome. I preferred a small, easily reviewable patch that doesn't add a bunch of new config options, with the tradeoff that the fine tuning would have to be done via well-documented operating system specific configurations.
I tested this patch by running a node with:
`./src/qt/bitcoin-qt -regtest -txindex -datadir=/tmp/node -zmqpubhashblock=tcp://127.0.0.1:28332 &`
and connecting to it with:
`python3 ./contrib/zmq/zmq_sub.py`
Without these changes, `ss -panto | grep 28332 | grep ESTAB | grep bitcoin` will report no keepalive timer information. With these changes, the output from the prior command will show keepalive timer information consistent with the configuration at the time of connection establishment, e.g.-: `timer:(keepalive,119min,0)`.
I also tested with a non-TCP transport and did not witness any adverse effects:
`./src/qt/bitcoin-qt -regtest -txindex -datadir=/tmp/node -zmqpubhashblock=ipc:///tmp/bitcoin.block &`

New getnodeaddresses call gives access via RPC to the peers known by the node. It may be useful for bitcoin wallets to broadcast their transactions over tor for improved privacy without using the centralized DNS seeds. getnodeaddresses is very similar to the getaddr p2p method.
Please advise me on the best approach for writing an automated test. By my reading the getaddr p2p method also isn't really tested.

5a5ea93e87c766dac1251f0369b2737d8e9dadde Doc: add information about security to the JSON-RPC doc (David A. Harding)
Pull request description:
This documents some information about using the RPC interface securely, as suggested in https://github.com/bitcoin-core/bitcoincore.org/pull/637 by @luke-jr and @TheBlueMatt. I think it should fit in well with #14458, but is not dependent on it (and shouldn't have any significant merge conflicts with it).

645e905c327411555073fa7964b36f652998059f doc: Add release notes for unloadwallet change to synchronous call (João Barbosa)
c37851de5752f107c16e19317f28038b6b7ca2dc rpc: Make unloadwallet wait for complete wallet unload (João Barbosa)
Pull request description:
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.
This PR makes the `unloadwallet` RPC synchronous, meaning that it blocks until the wallet is fully unloaded.
Replaces #14919, fixes#14917.

f1bd03eb013b96ff040a8f835e4137fbd2a38cda [depends, zmq, doc] upgrade zeromq to 4.2.5 and avoid deprecated zeromq api functions (mruddy)
Pull request description:
Upgrade the ZeroMQ dependency from version 4.2.3 to the latest stable version 4.2.5.
This PR Follows the lead of https://github.com/bitcoin/bitcoin/pull/11986.
I upgraded both patch files to correspond to the version `4.2.5` libzmq files.
I assume doing so is still necessary and correct.
Without updating the patch line numbers, things appear to work, but you get extra log messages while building `depends` because things don't exactly match, e.g.:
```
/bitcoin/depends> make zeromq
Extracting zeromq...
/bitcoin/depends/sources/zeromq-4.2.5.tar.gz: OK
Preprocessing zeromq...
patching file src/windows.hpp
Hunk #1 succeeded at 58 (offset 3 lines).
patching file src/thread.cpp
Hunk #1 succeeded at 307 with fuzz 2 (offset 87 lines).
Hunk #2 succeeded at 323 with fuzz 2 (offset 90 lines).
```
Updating the patches seemed cleaner, so I did it. Note that libzmq had some whitespace changes, so that's why the updated patches do too.
