6f6465cefc scripted-diff: [validation] Rename CheckInputs to CheckInputScripts (John Newbery)
Pull request description:
CheckInputs() used to check no double spends, scripts & sigs and amounts. Since
832e074, the double spend and amount checks
have been moved to CheckTxInputs(), and CheckInputs() now just validates
input scripts. Rename the function to CheckInputScripts().
Also fix incorrect comments.

Now that we require glibc 2.17+, #17538, we can remove linking in librt
for backwards compatibility purposes. The clock_* functions from librt
were merged into glibc as part of the 2.17 release.
* The `clock_*' suite of functions (declared in <time.h>) is now available
directly in the main C library. Previously it was necessary to link with
-lrt to use these functions. This change has the effect that a
single-threaded program that uses a function such as `clock_gettime' (and
is not linked with -lrt) will no longer implicitly load the pthreads
library at runtime and so will not suffer the overheads associated with
multi-thread support in other code such as the C++ runtime library.
https://sourceware.org/ml/libc-announce/2012/msg00001.html
Note that librt is already not linked by the RISC-V and AARCH64 binaries.

This PR includes the `test_bitcoin-qt` project in the msvc build. The project is already in the repo but is not part of the solution and therefore does not get built.
The test executable output from this project does not pass successfully on Windows (it may never have). This PR only builds the project and does not add a step to execute the tests.

Instead of using /16 netgroups to bucket nodes in Addrman for connection
diversification, ASN, which better represents an actor in terms
of network-layer infrastructure, is used.
For testing, asmap.raw is used. It represents a minimal
asmap needed for testing purposes.

4f4ae6f97e build: set AC_PREREQ to 2.69 (fanquake)
Pull request description:
We use build macros such as `AX_CHECK_LINK_FLAG`, that require >=2.64, so our configure should also require Autoconf >= 2.64. The build would already blow up if 2.64 wasn't available. i.e:
```bash
configure.ac:320: error: Autoconf version 2.64 or higher is required
build-aux/m4/ax_check_link_flag.m4:74: AX_CHECK_LINK_FLAG is expanded from...
```
For reference, Autoconf 2.69 was released in [April of 2012](https://lists.gnu.org/archive/html/autoconf/2012-04/msg00041.html).

If after a backup, an address is issued beyond the initial
keypool range and none of the addresses in this range
is seen onchain, if a wallet is restored from backup, even in
case of rescan, funds may be loss due to the look-ahead
buffer not being incremented and so restored wallet not detecting
onchain out-of-range address as derived from its seed.
This scenario is theoretically unavoidable due to the requirement
of the keypool to have a max size. However, given the default
keypool size, this is unlikely. Document better keypool size
implications to avoid user setting a too low value.

c78b123982 build: add -bind_at_load to hardened LDFLAGS (fanquake)
Pull request description:
This performs the same function as `-Wl,-z,now`, except for ld on macOS.
You can check the binaries using `otool -l`, and looking for the `LC_DYLD_INFO_ONLY` section; `lazy_bind_off` and `lazy_bind_size` should both be 0.
This seems to be the case with our current release binaries. However we can make the check, and applying the flag explicit in configure.
man ld:
```bash
-bind_at_load
Sets a bit in the mach header of the resulting binary which tells dyld
to bind all symbols when the binary is loaded, rather than lazily.
```

ea50e34b28 keypool: Move opportunistic TopUps from LegacyScriptPubKeyMan to CWallet and ReserveDestination (Andrew Chow)
bb2c8ce23c keypool: Remove superfluous topup from CWallet::GetNewChangeDestination (Andrew Chow)
Pull request description:
* The `TopUp()` in `CWallet::GetNewChangeDestination` is unnecessary as currently m_spk_man calls TopUp further down the call stack inside LegacyScriptPubKeyMan::ReserveKeyFromKeyPool (called by LegacyScriptPubKeyMan::GetReservedDestination). This also lets us prepare for future changes with multiple ScriptPubKeyMans in the wallet.
* An opportunistic `TopUp()` is moved from `LegacyScriptPubKeyMan::GetNewDestination` to `CWallet::GetNewDestination`.
* Another opportunistic `TopUp()` is moved from `LegacyScriptPubKeyMan::ReserveKeyFromKeyPool`
Moving opportunistic TopUps ensures that ScriptPubKeyMans will always be topped up before requesting Destinations from them as we cannot always rely on future ScriptPubKeyMan implementaions topping up internally.

Remove the forest of special exceptions, and simply log a short
message to the NET logging category when an exception happens during
packet processing. It is not good to panick end users with errors
that any peer can generate (let alone writing to stderr).
