42b589d18f scripts: test for MACHO control flow instrumentation (fanquake)
469a5bc4fa build: build Boost with -fcf-protection when targeting Darwin (fanquake)
Pull request description:
Addresses the macOS portion of #21888.
Build Boost with `-fcf-protection` when targeting Darwin. This should be ok, because our cross-compiler (Clang 10) supports the option, and I'd expect all versions of Apple Clang being used to compile Core would also support it. Building Boost with this option is required so that the `main` provided to `test_bitcoin` has instrumentation.
Note that the presence of instrumentation does not mean it will be used, as that is determined at runtime by the CPU.
From the Intel control flow enforcement documentation:
> The ENDBR32 and ENDBR64 instructions will have the same effect as the NOP instruction on Intel 64 processors that do not support CET. On processors supporting CET, these instructions do not change register or flag state. This allows CET instrumented programs to execute on processors that do not support CET. Even when CET is supported and enabled, these NOP–like instructions do not affect the execution state of the program, do not cause any additional register pressure, and are minimally intrusive from power and performance perspectives.
Follow up from #21135.

07bc22ef10 docs: improve make with parallel jobs description. (Klement Tan)
Pull request description:
Changed `use -jX here for parallelism` to `use "-j N" for N parallel jobs`
**Rationale**: In my opinion `use -jX here for parallelism` is quite ambiguous as it could be perceived as a single option without any argument. Ie running:
```sh
make -jX
```
Embarrassingly this caused me to be stuck for quite a long time until I opened the help menu for `make` but if I am the only one who faced this issue I would be happy to close this PR.

105941b726 net: use stronger AddLocal() for our I2P address (Vasil Dimov)
Pull request description:
There are two issues:
### 1. Our I2P address not added to local addresses.
* `externalip=` is used with an IPv4 address (this sets automatically `discover=0`)
* No `discover=1` is used
* `i2psam=` is used
* No `externalip=` is used for our I2P address
* `listenonion=1 torcontrol=` are used
In this case `AddLocal(LOCAL_MANUAL)` [is used](94f83534e4/src/torcontrol.cpp (L354)) for our `.onion` address and `AddLocal(LOCAL_BIND)` [for our](94f83534e4/src/net.cpp (L2247)) `.b32.i2p` address, the latter being [ignored](94f83534e4/src/net.cpp (L232-L233)) due to `discover=0`.
### 2. Our I2P address removed from local addresses even if specified with `externalip=` on I2P proxy restart.
* `externalip=` is used with our I2P address (this sets automatically `discover=0`)
* No `discover=1` is used
* `i2psam=` is used
In this case, initially `externalip=` causes our I2P address to be [added](94f83534e4/src/init.cpp (L1266)) with `AddLocal(LOCAL_MANUAL)` which overrides `discover=0` and works as expected. However, if later the I2P proxy is shut down [we do](94f83534e4/src/net.cpp (L2234)) `RemoveLocal()` in order to stop advertising our I2P address (since we have lost I2P connectivity). When the I2P proxy is started and we reconnect to it, restoring the I2P connectivity, [we do](94f83534e4/src/net.cpp (L2247)) `AddLocal(LOCAL_BIND)` which does nothing due to `discover=0`.
To resolve those two issues, use `AddLocal(LOCAL_MANUAL)` for I2P which is also what we do with Tor.

29c9e2c2d2 wallet: Do not iterate a directory if having an error while accessing it (Hennadii Stepanov)
Pull request description:
On Windows when `ListDatabases` tries to iterate any system folder, e.g., "System Volume Information", it falls into an infinite loop.
This PR fixes this bug. Now the `debug.log` contains:
```
2021-05-12T09:07:53Z ListDatabases: Access is denied D:/System Volume Information -- skipping.
```
An easy way to reproduce the bug and test this PR is to pass the `-walletdir=D:\` command-line option, and run the `listwalletdir` RPC, or File -> Open Wallet in the GUI menu.
Fixes#20081.
Fixes#21136.
Fixes#21904.

c30dd02cd8 refactor: remove redundant fOnlySafe argument (t-bast)
Pull request description:
The `fOnlySafe` argument to `AvailableCoins` is now redundant, since #21359 added a similar field inside the `CCoinControl` struct (see https://github.com/bitcoin/bitcoin/pull/21359#discussion_r591578684).
Not all code paths create a `CCoinControl` instance, but when it's missing we can default to using only safe inputs which is backwards-compatible.

dde69f20a0 p2p, bugfix: use NetPermissions::HasFlag() in CConnman::Bind() (Jon Atack)
Pull request description:
This is a bugfix follow-up to #16248 and #19191 that was noticed in #21506. Both v0.21 and master are affected.
Since #19191, noban is a multi-flag that implies download, so the conditional in `CConnman::Bind()` using a bitwise AND on noban will return the same result for both the noban status and the download status. This means that download peers are incorrectly not being added to local addresses because they are mistakenly seen as noban peers.
The second commit adds unit test coverage to illustrate and test the noban/download relationship and the `NetPermissions` operations involving them.
The final commit adds documentation and disallows calling `NetPermissions::ClearFlag()` with any second param other than `NetPermissionFlags` "implicit" -- per current usage in the codebase -- because `ClearFlag()` should not be called with any second param that is a subflag of a multiflag, e.g. "relay" or "download," as that would leave the result in an invalid state corresponding to none of the existing NetPermissionFlags. Thanks to Vasil Dimov for noticing this.

There are two issues:
1. Our I2P address not added to local addresses.
* `externalip=` is used with an IPv4 address (this sets automatically
`discover=0`)
* No `discover=1` is used
* `i2psam=` is used
* No `externalip=` is used for our I2P address
* `listenonion=1 torcontrol=` are used
In this case `AddLocal(LOCAL_MANUAL)` is used for our `.onion` address
and `AddLocal(LOCAL_BIND)` for our `.b32.i2p` address, the latter being
ignored due to `discover=0`.
2. Our I2P address removed from local addresses even if specified
with `externalip=` on I2P proxy restart.
* `externalip=` is used with our I2P address (this sets automatically
`discover=0`)
* No `discover=1` is used
* `i2psam=` is used
In this case, initially `externalip=` causes our I2P address to be added
with `AddLocal(LOCAL_MANUAL)` which overrides `discover=0` and works as
expected. However, if later the I2P proxy is shut down we do
`RemoveLocal()` in order to stop advertising our I2P address (since we
have lost I2P connectivity). When the I2P proxy is started and we
reconnect to it, restoring the I2P connectivity, we do
`AddLocal(LOCAL_BIND)` which does nothing due to `discover=0`.
To resolve those two issues, use `AddLocal(LOCAL_MANUAL)` for I2P which
is also what we do with Tor.
