Currently it's possible for ReleaseWallet to delete the CWallet pointer while
it is processing BlockConnected, etc chain notifications.
To fix this, unregister from notifications earlier in UnloadWallet instead of
ReleaseWallet, and use a new RegisterSharedValidationInterface function to
prevent the CValidationInterface shared_ptr from being deleted until the last
notification is actually finished.
ef35604c9c88e7800e9be106b791b1c0fa8b310a rpc: fix broken RPCExamples for waitforblock(height) (Sebastian Falbesoner)
Pull request description:
This PR fixes several broken RPCExamples from the "blockchain" category:
- `HelpExampleCli` for `waitforblock` (disturbing comma between arguments)
- `HelpExampleCli` for `waitforblockheight` (disturbing comma between arguments)
- `HelpExampleRpc` for `waitforblockheight` (disturbing quotation marks around integer argument)
Note that the CLI example for `waitforblockheight` would also work with the first argument in quotation marks (in contrast to the RPC example), but I removed them as well as they are not needed.
Outputs for the non-working examples in the master branch:

9ab14e4d21c73d16d8d782f1576fe29e659e2a70 Limit decimal range of numbers ParseScript accepts (pierrenn)
Pull request description:
Following up on this suggestion : https://github.com/bitcoin/bitcoin/pull/18413#issuecomment-602966490, prevent the output of `atoi64` in the `core_read.cpp:ParseScript` helper to send to `CScriptNum::serialize` values wider than 32-bit.
Since the `ParseScript` helper is only used by the tool defined in `bitcoin-tx.cpp`, this only prevents users to provide too much unrealistic values.

2b0fcff7f26d59fed4bcafd1602325122a206c67 Make VerifyWitnessProgram use a Span stack (Pieter Wuille)
Pull request description:
Here is a follow-up to #18002, again with the goal of simplifying (potential) BIP341 code.
Instead of passing a begin and end iterator of the initial stack to `ExecuteWitnessScript`, they are turned into a `Span<const valtype>`, representing a span of `valtype`s in memory. This allows `VerifyWitnessProgram` to operate on that span directly, instead of juggling iterators around (which would be exacerbated by #17977 if trying to avoid copying the stack).

Pull request description:
If we're mlocking something, it's because it's sensitive information. Therefore, don't include it in core dump files, ~~and unmap it from forked processes~~.
The return value is not checked because the madvise calls might fail on older kernels as a rule (unsure).

This is in preparation for adding different signature verification rules,
specifically tapscript (BIP 342), which interprets opcode 0xac and 0xad
as Schnorr signature verifications.
Both BitcoinApplication and OptionsModel classes are derived from the
QObject class, therefore a parent-child relation could be established to
manage the lifetime of an OptionsModel object.
This commit does not change behavior.

Data files are pre-allocated, and upon flush/finalization, they are trimmed down to their resulting size.
Block (blk) files are written to disk as blocks come in, which is often out of order, whereas undo (rev) files are written sequentially, as each block is added to the top of the chain.
When a block file hits the size limit, the system flushes and trims the file down to its final size, and moves on to the next block file.
Case 1: blocks are added to the chain as they come in (synced up node case) -- in this case, we will flush and finalize the undo file together with the block file.
Case 2: blocks are added to the chain after they have been downloaded (syncing node case) -- in this case, we postpone finalizing the undo file until we know the undo data for the last block in the file has been written to disk.
