Allow negative heights in RPC calls
For issue https://github.com/zcash/zcash/issues/2197
Currently adding the feature to `getblock` and `getblockhash`. There is another candidate: `getblocksubsidy` however i want to have some review about these 2 first before repeating what could be a bad approach.
Initialize ThreadNotifyWallets before additional blocks are imported
The intention of this PR is to address #4301. It seems `ThreadNotifyWallets` assumes that `chainActive.Tip()` on initialization reflects the wallet's view of the active tip, but prior to `ThreadNotifyWallets`'s initialization the active chain ends up being modified by blocks that are imported from disk, so our local `pindexLastTip` ends up out of sync with the wallet's actual "last" tip.
This PR moves the initialization of `ThreadNotifyWallets` to earlier in the process while passing in the current active tip. This addresses the problem for non-fresh nodes, and then for fresh nodes we have the notification thread wait until the genesis block has been loaded.
Change cm to cmu in sapling
Part of https://github.com/zcash/zcash/issues/3446
For each of the 2 commits, suggested change was made, then fixed build errors until compile. Finally ran bitcoin and gtests, both of them passing.
zcutil/fetch-params.sh unneeded --testnet arg should warn user
If fetch-params.sh user doesn't know that testnet and mainnet params are the same, and user specifies --testnet, it's confusing that the argument is ignored.
Upstream PRs relating to strMiscWarning
This pulls in upstream PRs bitcoin/bitcoin#7114 and bitcoin/bitcoin#9236 (non-QT parts).
* Fixesbitcoin/bitcoin#6809 - run-of-the-mill exceptions should not get into `strMiscWarning` (which is reported by `getinfo`).
* Eliminate data races for `strMiscWarning` and `fLargeWork*Found`. This moves all access to these data structures through accessor functions and protects them with a lock.
This moves all access to these datastructures through accessor functions
and protects them with a lock.
Relative to the upstream commit, we also add GetMiscWarning() to make this accessible to tests.

This is a first step in avoiding racy accesses to strMiscWarning.
By itself this commit causes a link error because global variables relating to alerts
are only accessible in the zcashd server, but util is used in other binaries.

All of these maps are created from scratch on wallet load, so we can
alter their contents without compatibility concerns. With this change,
we can use the existing maps to implement viewing key support. The
downside is that the wallet will take more space in memory, but that can
easily be improved in future by storing ExtFVK fingerprints in some of
the maps (which would improve memory usage even compared to the original
layout).
