54245985fb Squashed 'src/secp256k1/' changes from 0b70241850..b19c000063 (Pieter Wuille)
Pull request description:
It's been 1.5 years since our secp256k1 subtree was updated, while the upstream project has undergone a number of incremental improvements (performance, tests, build system fixes), plus gained the groundwork for batch verification.
As we're early in the 0.19 window, this seems like a good time to get these merged.

fa013664ae util: Add type safe GetTime (MarcoFalke)
Pull request description:
There are basically two ways to get the time in Bitcoin Core:
* get the system time (via `GetSystemTimeInSeconds` or `GetTime{Millis,Micros}`)
* get the mockable time (via `GetTime`)
Both return the same type (a plain int). This can lead to (test-only) bugs such as 99464bc38e.
Fix that by deprecating `GetTime` and adding a `GetTime<>` that returns the mockable time in a non-int type. The new util function is currently unused, but new code should it where possible.

fadbc5d895 mempool: remove unused magic number from consistency check (Gregory Sanders)
Pull request description:
Unexplained magic numbers are no good. Since the exact number does not matter, opt for a constant that is less peculiar.
Note that this could only possibly affect mempool consistency checks which is not active by default except on regtest.

If a transaction is already in-flight when a peer announces a new tx to us, we
schedule a time in the future to reconsider whether to download. At that future
time, there was a bug that would prevent transactions from being rescheduled
for potential download again (ie if the transaction was still in-flight at the
time of reconsideration, such as from some other peer). Fix this.
If a peer hasn't responded to a getdata request, eventually time out the request
and remove it from the in-flight data structures. This is to prevent any bugs in
our handling of those in-flight data structures from filling up the in-flight
map and preventing us from requesting more transactions (such as the NOTFOUND
bug, fixed in a previous commit).

9f85e9cb3d scripted-diff: Rename LockAnnotation to LockAssertion (practicalswift)
de9b5dbca3 Make sure the compile-time locking promises given via LockAnnotation:s hold also in practice at runtime (ifdef DEBUG_LOCKORDER) (practicalswift)
3a809446b3 Move LockAnnotation to make it reflect the truth (practicalswift)
cc2588579c Move LockAnnotation from threadsafety.h (imported code) to sync.h (our code) (practicalswift)
Pull request description:
`LockAnnotation lock(mutex);` is a guarantee to the compiler thread-analysis that `mutex` is locked (when it couldn't be determined otherwise).
Before this PR it was possible to make the mistake of adding a `LockAnnotation` where the correct mutex is _not_ held. This in turn makes the thread-analysis reasoning being based on incorrect premises.
This PR adds an assertion in the `LockAnnotation` ctor which checks that the guarantees given by us at compile-time are held also in practice (`ifdef DEBUG_LOCKORDER`).
Issues like the one described in #16028 will be discovered immediately with this PR merged.
Changes in this PR:
* Move `LockAnnotation` from `threadsafety.h` (imported code) to `sync.h` (our code)
* Move `LockAnnotation` in `wallet_tests` to make it reflect the truth
* Make sure the compile-time locking promises given via `LockAnnotation`:s hold also in practice at runtime (`ifdef DEBUG_LOCKORDER`)
* Rename `LockAnnotation` to `LockAssertion`

e23809a05b [rpc] deriveaddresses: Correct descriptor checksum in RPCExamples (Chris Capobianco)
Pull request description:
Trvial: This fixes the descriptor checksum found the in the deriveaddresses RPC example.
The current checksum value does work, but only if the "h" used for the hardened derivation key origin are replaced with "'".
Given the discussion to switch from "'" to "h" [here](https://github.com/bitcoin/bitcoin/issues/15740), I thought it made more sense to update the checksum rather then changing all the "h" to "'" in this example.

2c448d6bc7 parameterize hard coded numbers referring to miner conf window (Jordan Baczuk)
Pull request description:
Replace hard coded values (eg. 2016) with `mainnetParams.nMinerConfirmationWindow` where appropriate. This parameterizes hard coded values in the unit test that refer to the `Miner Confirmation Window`, which currently is `2016`. This includes values not exactly 2016 but which were derived from it. Also changed `int` to `uint32_t` where appropriate to avoid compiler warnings. This makes one source of truth, and also helps people who might be adjusting this value in testing so the unit tests don't break.

fa2b52af32 Disallow extended encoding for non-witness transactions (take 3) (MarcoFalke)
Pull request description:
(previous title "p2p: Disallow extended encoding for non-witness transactions (take 3)")
Remote peers can send us illegally encoded txs and thus have us write to stderr. Fix that by not writing to stderr.
This is a follow up to the previous (incomplete) attempts at this:
* Disallow extended encoding for non-witness transactions #14039
* Add test for superfluous witness record in deserialization #15893

ryanofsky:
utACK fa2b52af32. Would change title to something like "Avoid logging transaction decode errors to stderr" instead of "Disallow extended encoding for non-witness transactions." The current title is confusing because this PR isn't really allowing or disallowing anything, just logging the condition differently. "Disallow" also seems to contradict the "Allow exceptions from..." comments in the actual code.

0b09a57ae Give WalletModel::UnlockContext move semantics (Pieter Wuille)
Pull request description:
WalletModel::UnlockContext seems to implement "move upon copy" semantics; with C++11 this can be done more safely using move semantics (making attempts to actually copy fail instead).
Not a big deal if this isn't worth review time.

When writing all of the imported data to the wallet, use a common
WalletBatch object so that batch writes are done and the writes
finish more quickly.
AddKeypoolPubkey is no longer needed so it is also removed
