fa86c8aec6 init: Remove dead code in LoadChainTip (MarcoFalke)
Pull request description:
`LoadChainTip` sets `::ChainActive()` based on `pcoinsTip`'s best block. `LoadChainTip` is never called when that block is null, so we can remove all code from within that method that is only executed when that block is null.
Fixes#15967 Inconsistent locking behavior in LoadChainTip

01971da9bd docs: Add productivity notes for "dummy rebases" (Carl Dong)
Pull request description:
When rebasing, we often want to do a "dummy rebase" whereby we are not rebasing over an updated master. This is because rebases can be confusing enough already, and we don't want to resolve upstream conflicts together with our local rebase conflicts due to fixup commits, commit rearrangements, and such. This productivity section details how to do such "dummy rebase"s.

463921bb64 CKey: add method to negate the key (Jonas Schnelli)
Pull request description:
This adds a limited implementation of `HKDF` (defined by rfc5869) that supports only HMAC-SHA256 and length output of 32 bytes (will be required for v2 transport protocol).
This PR also includes a method to negate a private key which is useful to enforce public keys starting with 0x02 (or 0x03) (a requirement for the v2 transport protocol). The new `CKey::Negate()` method is pretty much a wrapper around `secp256k1_ec_privkey_negate()`.
Including tests.
This is a subset of #14032 and a pre-requirement for the v2 transport protocol.

This PR adds a new `passphrase` argument to `createwallet` which will create a wallet that is encrypted with that passphrase.
This is built on #15226 because it needs to first create an empty wallet, then encrypt the empty wallet and generate new keys that have only been stored in an encrypted state.

Pull request description:
This brings the behaviour of the import* calls closer to importmulti. After this change, the difference between importmulti and the other import* calls is
* that in importmulti you can "opt-out" of scanning early blocks by setting a later timestamp.
* that in importmulti the wallet will successfully import the data, but fail to rescan. Whereas in the other calls, the wallet will abort before importing the data.

c01c065b9d Do not construct out-of-bound pointers in SHA512/SHA1/RIPEMD160 code (Pieter Wuille)
Pull request description:
This looks like an issue in the current SHA256/512 code, where a pointer outside of the area pointed to may be constructed (this is UB in theory, though in practice every supported platform treats pointers as integers).
I discovered this while investigating #14580. Sadly, it does not fix it.

Also renames global methods for clarity:
- ::FlushStateToDisk() -> CChainState::ForceFlushStateToDisk()
- This performs an unconditional flush.
- ::PruneAndFlush() -> CChainState::PruneAndFlush()
along with DisconnectResult, and CBlockIndexWorkComparator.
The CChainState interface needs to be known to the rest of the system because
many global functions will move to CChainState methods. This is to allow
other parts of the system to be parameterized per chainstate instance
instead of assuming a single global.

Adds doxygen comments for the CKeyPool and CReserveKey objects. The way these work is pretty confusing and it's easy to overlook details (eg https://github.com/bitcoin/bitcoin/pull/15557#discussion_r271956393).

ccc27bdcd2 doc: Clarify -blocksdir usage (Daniel McNally)
Pull request description:
This PR attempts to clarify and correct the `-blocksdir` argument description and default value. `-blocksdir` does not refer to the full path to the actual `blocks` directory, but rather the root/parent directory which contains the `blocks` directory. Accordingly, the default value is `<datadir>` and not `<datadir>/blocks` - this behavior of defaulting to the datadir can also be seen in init.cpp:
```cpp
if (gArgs.IsArgSet("-blocksdir")) {
path = fs::system_complete(gArgs.GetArg("-blocksdir", ""));
if (!fs::is_directory(path)) {
path = "";
return path;
}
} else {
path = GetDataDir(false);
}
```
It also attempts to clarify that only the `.dat` files containing block data are impacted by `-blocksdir`, not the index files.
I believe this would close#12828.
