Note that this code change will not automatically repair a data directory that has been affected by this problem; that requires starting zcashd with the `-rescan` or `-reindex` options.
Add DNS seeders
New DNS seeders
----------------
This adds DNS seeders at "zfnd.org" and "yolo.money" to the list in `chainparams.cpp`. They're running [CoreDNS](https://coredns.io) with a [Zcash crawler plugin](https://github.com/ZcashFoundation/dnsseeder), the result of a Zcash Foundation in-house development effort to replace zcash-seeder with something memory-safe and easier to maintain.
DNS seeders hosted at "zfnd.org" and "yolo.money" have been added to the list in `chainparams.cpp`.

These are validly operated seeders per the [existing policy](https://zcash.readthedocs.io/en/latest/rtd_pages/dnsseed_policy.html). For general questions related to either seeder, contact george@zfnd.org or mention @gtank in the Zcash Foundation's Discord. For bug reports, open an issue on the [dnsseeder](https://github.com/ZcashFoundation/dnsseeder) repo.

RPC methods
------------
- Add `joinSplitPubKey` and `joinSplitSig` to JSON RPC output using TxToJSON. These two properties are required to fully reconstruct a Zcash transaction's binary form from the RPC data.
- Add `estimatedheight` to RPC `getblockchaininfo` response
- `joinSplitPubKey` and `joinSplitSig` have been added to verbose transaction outputs. This enables the transaction's binary form to be fully reconstructed from the RPC output.
- The output of `getblockchaininfo` now includes an `estimatedheight` parameter. This can be shown in UIs as an indication of the current chain height while `zcashd` is syncing, but should not be relied upon when creating transactions.
Initial Block Download
Metrics screen
-----------------------
- Add a progress bar when in Initial Block Download mode. The progress bar shows both headers and blocks. It is only printed for TTY output. Additionally, the "not mining" message is no longer shown on mainnet, as the built-in CPU miner is not effective at the current network difficulty.
- Report the number of block headers prefetched during Initial Block Download. With current compile-time defaults, a Zcash node prefetches up to 160 block headers per request without a limit on how far it can prefetch, but only up to 16 full blocks at a time.
- A progress bar is now visible when in Initial Block Download mode, showing both the prefetched headers and validated blocks. It is only printed for TTY output. Additionally, the "not mining" message is no longer shown on mainnet, as the built-in CPU miner is not effective at the current network difficulty.
- The number of block headers prefetched during Initial Block Download is now displayed alongside the number of validated blocks. With current compile-time defaults, a Zcash node prefetches up to 160 block headers per request without a limit on how far it can prefetch, but only up to 16 full blocks at a time.
