Outbound peer logic prevents connecting to addresses that we're already
connected to, so prevent inadvertent eviction of current peers via
test-before-evict by checking this condition and marking current peer's
addresses as Good().
Co-authored-by: John Newbery <john@johnnewbery.com>
Being able to invoke Good() is important for address management (new vs tried
table, tried table eviction via test-before-evict). We mitigate potential
information leaks by not calling Connected() on these peer addresses.
Starting with the Clang shipped with Xcode 12, Apple has enabled
-Werror=implicit-function-declaration by default. This causes bdbs mutex
detection to fail when building on macOS (not cross-compiling):
checking for mutexes... UNIX/fcntl
configure: WARNING: NO SHARED LATCH IMPLEMENTATION FOUND FOR THIS PLATFORM.
configure: error: Unable to find a mutex implementation
as previously emitted warnings are being turned into errors. i.e:
error: implicitly declaring library function 'exit' with type 'void (int) __attribute__((noreturn))' [-Werror,-Wimplicit-function-declaration]
Append -Wno-error=implicit-function-declaration to cflags so that
-Wimplicit-function-declaration returns to being a warning, and the
configure checks will succeed.
Fixes#19411.
fa9b48549c test: Add test for -blockversion (MarcoFalke)
fa7fb0e442 test: Default blockversion to 4 in feature_block (MarcoFalke)
fa2b778d0c test: Remove unused -blockversion from tests (MarcoFalke)
Pull request description:
`-blockversion` is currently untested, as in: The setting could be made a no-op without any tests failing. Fix that by adding an explicit test for it. Also, related minor cleanups.

Pull request description:
This PR is a #19077 follow up, and it addresses the [comment](https://github.com/bitcoin/bitcoin/pull/19077#discussion_r504805234):
> If need to update, there are two corrections that could be made:
>
> * Line 69 "Wallets are Berkeley DB (BDB) databases" is no longer true
>
> * Line 76 "Wallet lock file" should say "BDB wallet lock file"
