Zcash: Excluding changes to code we haven't backported yet that cause
too many conflicts.
When -blocksonly is set to 1, it interacts with the -walletbroadcast
parameter and sets it to 0 if it has not been set already.This behavior
is not captured by the current documentation, which claims that -blocksonly
does not impact any wallet transactions.
(cherry picked from commit 621e86ee8d0102e2bf41f7656a368083b89b2f83)
Zcash: Excludes max-peer doc changes, since we don't have
block-relay-only peers yet.
Zcash: just a comment fix, no need to blacklist as -whitelistalwaysrelay
will never have been active.
(cherry picked from commit 89d113e02a83617b4e971c160d47551476dacc71)
Also renames whitelistalwaysrelay.
Nodes relay all transactions from whitelisted peers, this
gets in the way of some useful reasons for whitelisting
peers-- for example, bypassing bandwidth limitations.
The purpose of this forced relaying is for specialized gateway
applications where a node is being used as a P2P connection
filter and multiplexer, but where you don't want it getting
in the way of (re-)broadcast.
This change makes it configurable with whitelistforcerelay.

Zcash: Was "Added -whiteconnections=<n> option" from bitcoin/bitcoin#5288. The
option was later removed in bitcoin/bitcoin#6374 which we merged in #1258. This
commit contains the difference between the two.
Remove bad chain alert partition check
(cherry picked from https://github.com/bitcoin/bitcoin/pull/8275 commit ab8be98fdb25b678a8cd7e89adf06d1b1f6bdd62), original commit message:
As per meeting 2016-03-31
https://bitcoincore.org/en/meetings/2016/03/31/#bad-chain-alerts
The partition checker was producing huge number of false-positives
and was disabled in 0.12.1 on the understanding it would either be
fixed in 0.13 or removed entirely from master if not.
* -maxuploadtarget can be set in MiB
* if <limit> - ( time-left-in-24h-cycle / 600 * MAX_BLOCK_SIZE ) has reach, stop serve blocks older than one week and filtered blocks
* no action if limit has reached, no guarantee that the target will not be surpassed
* add outbound limit informations to rpc getnettotals
Zcash: Also includes a cleanup from bitcoin/bitcoin#5697

This removes the last implicit dependency on libsodium from
libzcashconsensus.
As of zcash/zcash#4893 we no longer depend on libsodium for Ed25519
signature verification.
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.
Zcash: Added an extra command to handle cases where the pair were not
separated by a space.

Small httpserver.cpp backports
Also includes a change to the `uiInterface.NotifyBlockTip` signal API.
These remove merge conflicts from subsequent backports for `sync.h`.
Cherry-picked from the following upstream PRs:
- bitcoin/bitcoin#6859
- bitcoin/bitcoin#7112
- Only the non-QT changes.
- bitcoin/bitcoin#7966
- bitcoin/bitcoin#8421
- We already backported the second commit in zcash/zcash#2555
After CWallet::ChainTipAdded() updates the witness data, it
may flush it to disk (SetBestChain()); make sure the locator
part is consistent with the witnesses (height).
Improvements to tracing initialization
The refactor makes it easier to implement further tracing customisations.
We also now have spans for `zcashd` initialization and shutdown.
Refactor ProofVerifier
`ProofVerifier` was previously used to conditionally verify pre-Sapling Sprout
proofs (based on `ProofVerifier::Strict` or `ProofVerifier::Disabled` being
used), but hybrid Sprout proofs bypassed it (so were being verified multiple
times during block verification), and once `libsnark` was removed in
zcash/zcash#4060 `ProofVerifier::check` was doing nothing.
This PR refactors `ProofVerifier`, moving it out of the `libzcash` compilation
unit (so that it can depend on `primitives/transaction.h`), and moving Sprout
verification from `JSDescription::Verify` to `ProofVerifier::VerifySprout`.
Verification-skipping for Sprout proofs is re-introduced.
Additionally, the `ZCJoinSplit` global is removed from the codebase, and
`ZCJoinSplit::prove` is converted into a static function. We load the hybrid
Sprout parameters dynamically at proving time within the Rust code, and no
longer require a C++ global for any proving parameters.
As a side-effect, `libzcashconsensus.la` building with `--with-libs` is fixed,
as `primitives/transaction.cpp` no longer depends on `librustzcash.h`.
We don't support making pre-Sapling JoinSplit proofs, and we load the
parameters for post-Sapling JoinSplit proofs at proving time, so there
is no need for a global ZCJoinSplit to be passed through the APIs.
Add funding streams to consensus parameters.
Add funding stream payments to coinbase txns generated by the miner.
* Reduce valueBalance for shielded outputs to funding streams.
* Ensure we produce binding signatures in any case where shielded
outputs go to either a funding stream or the miner.
This patch adds an option to configure the name and/or directory of the
debug log.
The user can specify either a relative path, in which case the path
is relative to the data directory. They can also specify an absolute
path to put the log anywhere else in the file system.
Add -lightwalletd experimental option
Similar to `-insightexplorer` but loading less indexes.
After testing and code review this should be able to close https://github.com/zcash/zcash/issues/4326
Explanation: if a signal interrupts certain syscalls such as `open`, `read`, or `write`,
then the library function will by default fail with `errno` `EINTR`. But we almost never
check for `EINTR`, so this is likely to cause spurious errors. We want to restart the syscall
instead, which is what `SA_RESTART` is intended to do. Since our signal handlers (defined
in init.cpp) only set a flag, restarting the syscall is safe and is always the Right Thing.

Fix race conditions during init
Fix race conditions due to accessing `chainActive.Tip()` during init, and other minor cleanups.
Includes backport of https://github.com/bitcoin/bitcoin/pull/8063 .
Shows reindex progress in metrics screen
Resolves issue #3813.
The "Downloading blocks" message is changed to "Reindexing blocks" during reindex, after reindex is completed the text is reverted back to the first variant.
Reindex progress is shown as a sum of processed file size (we can't use reindexed block number as a progress because we can't predict how many blocks to process at all, we don't know the size of the block before we process it), the result looks like
```
Reindexing blocks | 22.64 MiB / 336.00 MiB (6%, 13583 blocks)
```
Refactor experimental feature handling
Adds new rpc call `getexperimentalfeatures` and also adds experimental features to `getblockchaininfo` output.
Closes#2671.
Remove time adjustment; instead warn if peer clocks are too different
The policy is: warn if we have seen at least 8 (TIMEDATA_WARNING_SAMPLES) peer times, in the version messages of the first 20 (TIMEDATA_MAX_SAMPLES) unique (by IP address) peers that connect, that are more than 10 minutes (TIMEDATA_WARNING_THRESHOLD seconds) but less than 10 days (TIMEDATA_IGNORE_THRESHOLD seconds) away from local time.
