Does the bare minimum to introduce Taproot wallet support with CT; just
adds a CPubKey blinding_pubkey to the taproot destination variant and
updates some visitors.
In future when we define blech32 we will need to make sure we are using
that encoding and using the pubkey.
e65d1d4986 doc: recommend `--disable-external-signer` in OpenBSD build guide (Sebastian Falbesoner)
Pull request description:
Building the master branch with the default build settings (i.e. with external signer support enabled) leads to the following errors on my OpenBSD 6.9 machine:

This PR recommends passing `--disable-external-signer` in the OpenBSD build guide ([as suggested by laanwj](https://github.com/bitcoin/bitcoin/pull/22294#issuecomment-867452411)). The same commit also bumps the OpenBSD version mentioned in the header to 6.9 -- I recently used this document to setup a Bitcoin Core build on 6.9 and the description and all mentioned versions were still valid (before external signer support was enabled by default).
Would be nice if another OpenBSD user could confirm the build error.

I hacked up rpc_fundrawtransaction.py a little bit because our `get_address`
method here depends on nobody having called `createwallet` on a particular
node ... the "correct" fix for this would be to redo the Elements changes
to this functional test for the 0.20+ createwallet changes, but because
there will be big future changes to this test (in Elements #900 (PSET))
I did the quick/hacky thing, and will defer cleanups to a separate
post-rebase PR.
05f9770c1f doc: Clarify developer notes about constant naming (Russell Yanofsky)
Pull request description:
I'm pretty sure developer notes were intended to say constants should be upper case and variables should be lower case, but right now they are ambiguous about whether to write:
```c++
extern const int SYMBOL;
```
or:
```c++
extern const int g_symbol;
```
First convention above is better than the second convention because it tells you without having to look anything up that the value of `SYMBOL` won't change at runtime. Also I haven't seen other c++ projects using the second convention.
