Since the wallet ecosystem may not be fully updated to handle
v5 transaction parsing at the point of NU5 activation, some
nodes may prefer to construct V4 transactions when not including
Orchard transaction components.
This change adds a CLI flag that allows node users to specify
that preference.
Call sync.h primitives "locks" and "mutexes" instead of "blocks" and "waitable
critical sections" to match current coding conventions and c++11 standard
names.
This PR does not rename the "CCriticalSection" class (though this could be done
as a followup) because it is used everywhere and would swamp the other changes
in this PR. Plain mutexes should mostly be preferred instead of recursive
mutexes in new code anyway.

If the user somehow manages to get into ShutdownRequested before
ThreadImport gets to ActivateBestChain() we may hang waiting on
condvar_GenesisWait forever. A simple wait_for and
ShutdownRequested resolves this case.

Zcash: We set the Sprout tree root on the genesis block's index file in
InitBlockIndex because we were implicitly relying on this occurring via
ActivateBestChain previously.
(cherry picked from commit bitcoin/bitcoin@0fd2a33648)
The -reindex option causes the node to first read the block files,
adding each block to the block index, then reset the reindexing flag,
then build the best chain (the "UpdateTip: new best" logging messages).
Before the wallet notification thread begins to actually do
notifications, it should wait until we're no longer in initial block
download, rather than waiting until the reindexing flag is reset (which
is too early).
This adds an `-allowdeprecated` CLI parameter whose value is a flag
indicating a deprecated feature that should be explicitly enabled.
Multiple instances of this argument may be provided. In the case that
this parameter is not provided, all currently deprecated RPC methods
that are not slated for removal in the next release remain available.
A user may disable all deprecated features entirely by providing the
string "none" as the argument to this parameter, or enable all
deprecated features, including those slated for removal, by providing
the string "all" as the argument to this parameter. In the case that
"all" or "none" is specified, multiple invocations of `-allowdeprecated`
are not permitted.
To explicitly enable only a specific set of deprecated features, use
`-allowdeprecated=<flag1> -allowdeprecated=<flagN> ...` when starting
zcashd. The following flags are recognized:
- "all" - enables all deprecated features.
- "none" - disables all deprecated features.
- "legacy_privacy" - enables the use of the deprecated "legacy" privacy
policy for z_sendmany. This causes the default behavior to conform to
the `FullPrivacy` directive in all cases instead of just for
transactions involving unified addresses.
- "getnewaddress" - enables the `getnewaddress` RPC method.
- "z_getnewaddress" - enables the `z_getnewaddress` RPC method.
- "zcrawreceive" - enables the `zcrawreceive` RPC method.
- "zcrawjoinsplit" - enables the `zcrawjoinsplit` RPC method.
- "zcrawkeygen" - enables the `zcrawkeygen` RPC method.
- "addrtype" - when this option is set, the deprecated `type` attribute
is returned in addition to `pool` or `address_type` (which contain the
same information) in the results of RPC methods that return address metadata.
(provided that the wallet is enabled and pruning is disabled,
and unless `-rescan=0` is specified explicitly).

In #5809, we attempted to fix the assumption that on startup, the
wallet's best chain was at the same position as the node's chain tip.
This did not account for a condition where the node's block index
might not contain the block corresponding to the wallet's best chain,
because the node had crashed before the block index containing that
block could be written to disk.
This commit adds handling so that the `ThreadNotifyWallets` thread
will not start until the wallet's best block has been restored
to the node's block index and we're able to obtain a pointer to
that state.
This more accurately reflects its meaning, as it corresponds to the most
recently persisted best chain (i.e. the chain tip that the wallet will
return to on restart), rather than the chain tip to which the in-memory
wallet state has been synced.
The previous code assumed that the last chain tip notified to the wallet
was equal to the node's chain tip at startup. However, this assumption
fails if the node shuts down uncleanly, or if a wallet file is moved
from one node to another.
We now try to start notifying from the wallet's best block, and if the
node doesn't have that block we fall back to the node's chain tip like
before.
Closeszcash/zcash#5805.
When a user supplies a unified address as the source of funds
for z_sendmany, the previous behavior could have risked user
privacy by spending transparent UTXOs belonging to different
diversified addresses in the same transaction, thereby linking
those addresses, and consequently any diversified shielded
receivers of unified addresses containing those transparent
receivers.
This change limits selection of transparent UTXOs to only those
explicitly associated with the unified receivers of the provided
source UA. Also, if a UA is provided as the source, the behavior
is maintained that only shielded notes in pools corresponding to
the receivers of that UA will be selected.
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.
This test-only change allows python (rpc) tests to specify, for example,
that NU5 should be activated at height X, without having to specify all
the previous network upgrades. Previous upgrades can (and must) still be
specified if they activate at different block heights (than, in this
example, NU5). This makes tests easier to write (and read), especially
as the number of network upgrades increases over time.
Note that this change only affects zcashd behavior in regtest mode. For
the other network modes (testnet and mainnet), the activation heights
are hard-coded in chainparams.cpp.
Move mempool rejections to debug category `mempoolrej`, to make it possible
to show them without enabling the entire category `mempool` which is
high volume.
