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 reached 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followed) is outdated.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
header file

It had been expected that the vcpkg manifest mechanism introduced in #19960 would do this automatically but it turns out not to be the case.

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,
"result": "Already at latest version. Wallet version unchanged."
}
```
...better feedback after successfully upgrading
```
{
"wallet_name": "watch-only",
"previous_version": 159900,
"current_version": 169900,
"result": "Wallet upgraded successfully from version 159900 to version 169900."

e95aaefe2540cb76969818fcc2ff77d33448ed5a 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)
I am on macOS 10.15.

8f7d1b39efbe65ab2747c593cc3560d4a449a333 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.
1. Commit where `CXX` was introduced: 374f96516a
2. Commit where `CXXFLAGS` was introduced: 5d49abc1f2
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.
