Remove ability of mining code to fill part of a block with transactions sorted by coin age.
(cherry picked from commit bitcoin/bitcoin@272b25a6a9)
Zcash:
* Add release notes.
* Remove a static assertion that no longer applies.
* Spell "prioritise" and "prioritisation" (when referring to tx prioritisation) consistently
with 'ise', to match the "prioritisetransaction" RPC call.

Under some circumstances it is possible for there to be a significant,
discontinuous jump in a node's clock value. On mining nodes, this can
result in block templates which are no longer valid due to time-based
nLockTime constraints. UpdateTime() is modified so that it will never
decrease a block's nLockTime, thereby preventing such invalidations.

Zcash: Updated CreateNewBlock_validity test and wallet_1941 RPC test to
ensure we satisfy the future timestamp soft fork rule.
The initial value for the provided return value is now `std::nullopt`
instead of the default value of the `MinerAddress` variant. This makes
it easier to distinguish "no miner address was provided" from "invalid
miner address".
This adds a new `AddrSet` type for use in note retrieval
as a filter, in place of a heterogeneous list of `RawAddress`
values. `RawAddress` will complicate the handling of addresses
within the wallet after the addition of unified addresses,
because it does not contain transparent receiver types, and
if we retain this polymorphism it means a lot of invalid states
are represented in places we don't want them to be. It's better
to figure out what types of addresses we're working with as soon
as possible after parsing, and use monomorphic calls from there
on in.
The addition of `UnifiedAddress` to the `PaymentAddress` type
introduced the need for methods that interact with payment addresses
to support transparent receivers as shielded ones, which is somewhat
inconsistent with previous uses of the `PaymentAddress` type.
This commit adds both `CKeyID` and `CScriptID` as new variants
of the `PaymentAddress` type. Following commits will shift encoding
and decoding to use the `PaymentAddress` type exclusively wherever
possible, rather than the current mix of `CDestination` and
`PaymentAddress` that complicates the wallet codebase.
The presence of this variant results in a situation where more
of the code than necessary needs to be aware of and handle
decoding failures. This change moves all handling of decoding
failures to the point of decoding.
We added support for the NU5 consensus rules in v4.5.0, which alters the
block header to contain a `hashBlockCommitments` value instead of the
chain history root. However, the output of `getblocktemplate` wasn't
returning this value; once NU5 activated, the `blockcommitmentshash`
field was being set to "null" (all-zeroes).
In v4.6.0 we added full NU5 support to `getblocktemplate`, by adding a
`defaultroots` field that gave default values for `hashBlockCommitments`
and the components required to derive it. However, in doing so we
introduced a regression in the (now-deprecated) legacy fields, where
prior to NU5 activation they contained nonsense.
This commit fixes the output of `getblocktemplate` to have the intended
semantics for all fields:
- The `blockcommitmentshash` and `authdataroot` fields in `defaultroots`
are now omitted from block templates for heights before NU5 activation.
- The legacy fields now always contain the default value to be placed
into the block header (regaining their previous semantics).

This reverts aeb089ecc7, which introduced
logging, adding a dependency on libbitcoin_util.a to libzcashconsensus.a.
Also adds missing #includes that were being indirectly included via
prevector.h including util.h.

Since the introduction of the ScriptForMining callback, the mining
functions (setgenerate and generate) crash with an assertion failure
(due to a NULL pointer script returned) if the keypool is empty. Fix
this by giving a proper error.
Zcash: Adapted to our MinerAddress type.
