Pull request description:
In packages where we are passing `-std=c++11` switch to `-std=c++17`, or, `-std=c++1z` in the case of Qt.
This PR also contains a [commit](104e859c97) that improves debug output when building Qt for debugging (`DEBUG=1`).
Now we'll get output like this:
```bash
g++ -c -pipe -ffunction-sections -O2 -fPIC -std=c++11 -fno-exceptions <lots more> ../../corelib/kernel/qcoreapplication.cpp
```
rather than just:
```bash
compiling ../../corelib/kernel/qcoreapplication.cpp
```
Note that when you look at the DEBUG output for these changes when building Qt, you'll see objects being compiled with a mix of C++11 and C++17. The breakdown is roughly:
1. `qmake` built with `-std=c++11`:
```bash
Creating qmake...
make[1]: Entering directory '<trim>/qt/5.9.8-4110fa99945/qtbase/qmake'
g++ -c -o project.o -std=c++11 -ffunction-sections -O2 -g <trim> <trim>/qt/5.9.8-4110fa99945/qtbase/qmake/project.cpp
# when qmake, Qt also builds some of it's corelib, such as corelib/global/qmalloc.cpp
g++ -c -o qmalloc.o -std=c++11 -ffunction-sections -O2 -g <trim> <trim>/qt/5.9.8-4110fa99945/qtbase/src/corelib/global/qmalloc.cpp
```
2. `qmake` is run, and passed our build options, including `-c++std`:
```bash
make[1]: Entering directory '<trim>/qt/5.9.8-4110fa99945/qtbase'
<trim>qt/5.9.8-4110fa99945/qtbase/bin/qmake -o Makefile qtbase.pro -- -bindir <trim>/native/bin -c++std c++1z -confirm-license <trim>
```
3. After some cleaning and configuring, we actually start to build Qt, as well as it's tools and internal libs:
```bash
Building qt...
make[1]: Entering directory '<trim>/qt/5.9.8-4110fa99945/qtbase/src'
# build libpng, zlib etc
gcc -c -m64 -pipe -pipe -O1 <trim> -o .obj/png.o png.c
# build libQt5Bootstrap, using C++11, which again compiles qmalloc.cpp
make[2]: Entering directory '<trim>/qt/5.9.8-4110fa99945/qtbase/src/tools/bootstrap'
g++ -c -pipe -ffunction-sections -O2 -fPIC -std=c++11 <trim> -o .obj/qmalloc.o ../../corelib/global/qmalloc.cpp
# build a bunch of tools like moc, rcc, uic, qfloat16-tables, qdbuscpp2xml, using C++11
g++ -c -pipe -O2 -std=c++11 -fno-exceptions -Wall -W <trim> -o .obj/rcc.o rcc.cpp
# from here, Qt is compiled with -std=c++1z, including qmalloc.cpp, for the third and final time:
g++ -c -include .pch/Qt5Core <trim> -g -Og -fPIC -std=c++1z -fvisibility=hidden <trim> -o .obj/qmalloc.o global/qmalloc.cpp
```
4. Finally, build tools like `lrelease`, `lupdate`, etc, but back to using -std=c++11
```bash
make[1]: Entering directory '<trim>/qt/5.9.8-4110fa99945/qttools/src/linguist/lrelease'
g++ -c -pipe -O2 -std=c++11 -fno-exceptions -Wall -W <trim> -o .obj/translator.o ../shared/translator.cpp
```
If you dump the debug info from the built Qt libs, they should also tell you that they were compiled with `C++17`:
```bash
objdump -g bitcoin/depends/x86_64-pc-linux-gnu/lib/libQt5Core.a
GNU C++17 9.3.0 -m64 -mtune=generic -march=x86-64 -g -O1 -Og -std=c++17 -fPIC -fvisibility=hidden -fvisibility-inlines-hidden -fasynchronous-unwind-tables -fstack-protector-strong -fstack-clash-protection -fcf-protection
```

3ebde2143a [test] Fix wait condition in disconnect_p2ps (Amiti Uttarwar)
Pull request description:
#19315 currently has a [test failure](https://cirrus-ci.com/task/4545582645641216) because of a race. `disconnect_p2ps` is intended to have a `wait_until` clause that prevents this race, but the conditional doesn't match since its comparing two different object types. `MY_SUBVERSION` is defined in messages.py as a byte string, but is compared to the value returned by the RPC. This PR simply converts types to ensure they match, which should prevent the race from occurring.

8008ef770f qt: unlock wallet "OK" button bugfix (Michael Dietz)
Pull request description:
When trying to send a transaction from an encrypted wallet, the ask
passphrase dialog would not allow the user to click the "OK" button
and proceed. Therefore it was impossible to send a transaction
through the gui. It was not enabling the "OK" button after the
passphrase was entered by the user, because it was using the same
form validation logic as the "Change passphrase" flow.
I reported this in a comment in https://github.com/bitcoin-core/gui/issues/136. But then I realized this seems to be a flat out bug.

comparing this value to the value returned by the RPC. Convert to ensure the
types match.

e416cfc92b Add MAX_STANDARD_SCRIPTSIG_SIZE to policy (sanket1729)
Pull request description:
Bitcoin core has a standardness rule for max satisfaction script sig size.
This PR adds to the policy header file so that it is documented along with
along policy rules. The initial reasoning that 1650 is an implicit
limit(would not reach assuming all other policy rules are being
followed) is outdated.
As we now know, bitcoin transactions can have spend conditions are more than
just signatures and there may exist p2sh transactions involving 100 byte
preimages that maybe non-standard because of this rule. Because this
rule is no longer implicit, we should explicitly document it in policy

Replaces #19382 with a different approach. See [this comment](https://github.com/bitcoin/bitcoin/pull/19382#discussion_r446332852) for the reasoning behind the switch.
--
Description from #19382:
See [here](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0936r0.pdf) for more detail on lifetimebound.
This is implemented using preprocesor macros rather than configure checks in order to keep span.h self-contained.
The ```[[clang::lifetimebound]]``` syntax was chosen over ```__attribute__((lifetimebound))``` because the former is more flexible and works to guard ```this``` as well as function parameters, and also because at least for now, it's available only in clang.
There are currently no violations in our codebase, but this can easily be tested by inserting one like this somewhere and compiling with a modern clang:
```c++
Span<const int> bad(std::vector<int>{1,2,3});
```
The result:
> warning: temporary whose address is used as value of local variable 'bad' will be destroyed at the end of the full-expression [-Wdangling]
Span<const int> bad(std::vector<int>{1,2,3});

Pull request description:
This follows up on #18836 and #20282 to fix and improve the as-yet unreleased `upgradewallet` feature and also implement review follow-up in https://github.com/bitcoin/bitcoin/pull/18836#discussion_r519328607.
This PR fixes 4 upgradewallet issues:
- this bug: https://github.com/bitcoin/bitcoin/pull/20403#discussion_r526063920
- it returns nothing in the absence of an RPC error, which isn't reassuring for users
- it returns the same thing both in the case of a successful upgrade and when no upgrade took place
- the error message object is currently dead code
This PR fixes the above and provides:
...user feedback to not silently return without upgrading
```

"wallet_name": "disable private keys",
"previous_version": 169900,
"current_version": 169900,

e95aaefe25 build: Avoid secp256k1.h include from system (Niklas Gögge)
Pull request description:
While building i ran into an error because i had a version of `secp256k1.h` under `/usr/local/include` that was incompatible with the secp256k1 code in the repository. This caused a problem because `$(BOOST_CPPFLAGS)` contained `-I/usr/local/include` and the include paths are searched by the compiler in order from left to right, so in the end `$(BITCOIN_INCLUDES)` contained `-I/usr/local/include` before `-I$(srcdir)/secp256k1/include` which caused the compiler to find `secp256k1.h` under `/usr/local/include`.
Looking at git blame i am wondering how this has not happened to anyone else in several years: cb89e18845/src/Makefile.am (L25)

8f7d1b39ef Fix QPainter non-determinism on macOS (Andrew Chow)
Pull request description:
Aplies a patch to Qt that fixes the non-determinism by modifying Qt. The source of the non-determinism is how LLVM 8 optimizes qt_intersect_spans when compiling. The particular optimization that seems to be causing the problems is that a temp variable is being added for spans->y. For some reason, when it does this, it chooses different instructions to use when making that variable. We bypass this problem by patching qt_intersect_spans to always make and use this local variable.

Pull request description:
This PR improves the robustness of our boost package in depends, most notably:
1. Bumps boost from `1.70.0` to `1.71.0`, because `1.71.0`:
1. Removes the need to patch out the unused variable.
f8462a6d27/depends/packages/boost.mk (L36)
Upstream boost patched it out in d20b64cf37, which was first included in the `1.71.0` release
2. Comes packaged with a version of `b2` which allows us to override its `CXX` and `CXXFLAGS`. Previously, choosing a toolset while building `b2` such as `clang` or `gcc` would force `b2`'s build system to invoke the compiler as a bare, hardcoded `clang` or `gcc`. However, our `depends` build system often want to customize this behaviour, adding extra flags or invoking the compiler by an alternate name. So this is useful.

2. The boost package is now split into `native_b2` and `boost`, better representing what actually happens.
- In our `depends` build system, we have a distinction between `native` packages and non-`native` packages. The output of `native` packages are meant to be used on the machine that's performing the build, and the output of non-`native` packages are meant to be used on/for the machine that will ultimately be running bitcoin. Previously, `boost` existed in `depends` as a non-`native` package, but that's partly inaccurate because the `./bootstrap.sh` invocation in its `$(package)_config_cmds` stage actually produced a binary called `b2`, which is run on the machine that's performing the build. This means that `b2` is a `native` package which is being built in an environment set up for the non-`native` package `boost`. This reveals a hidden unintended behavior in our `depends` build system: for linux->darwin cross builds, we use `gcc` for `native` packages, and `clang` for non-`native` packages. But `b2` was actually being built using `clang`, since it was being built in an environment set up for non-`native` packages.

Aplies a patch to Qt that fixes the non-determinism by modifying Qt. The
source of the non-determinism is how LLVM 8 optimizes qt_intersect_spans
when compiling. The particular optimization that seems to be causing the
problems is that a temp variable is being added for spans->y. For some
reason, when it does this, it chooses different instructions to use when
making that variable. We bypass this problem by patching
qt_intersect_spans to always make and use this local variable.
b87caf10b5 test: add is_bdb_compiled helper (Sjors Provoost)
Pull request description:
Followup for #20202, needed by #16546.
Allow the functional test suite to skip tests that require BDB, as well as introduce specific logic to handle whether BDB support is enabled or not. It follows the same pattern as `skip_if_no_sqlite` and `is_sqlite_compiled`.
