29aaf13b0a Make max tip age an option instead of chainparam 
After discussion in #7164 I think this is better.

Max tip age was introduced in #5987 to make it possible to run
testnet-in-a-box. But associating this behavior with the testnet chain
is wrong conceptually, as it is not needed in normal usage.
Should aim to make testnet test the software as-is.

Replace it with a (debug) option `-maxtipage`, which can be
specified only in the specific case.

Sapling merkle tree implementation

Closes #3056.

Please also review https://github.com/zcash/librustzcash/pull/8

This PR:

1. Introduces ZCSaplingIncrementalMerkleTree using Pedersen hashes.
2. Adds support for Sapling anchors into consensus rules. (Adds commitments, checks anchors are correct, handles block (dis)connects, etc.)
3. Handles mempool eviction for obsolete anchors.
4. Enforces correctness of block's Sapling root field
5. Changes miner to correctly apply the Sapling root to the block header
6. Handles mempool consistency checks for anchors

I wrote this patch as part of making a Bazel build system but it really is independent from that so I'm putting this as a separate PR.

External linkage does not help and just encourages sloppy dependencies (ie using symbols only declared in a cpp file in some other cpp file) and can lead to weird issues when there are name collisions.
