Daira Hopwood bc909a7a7f Replace http with https: in links to the MIT license. 
Also change MIT/X11 to just MIT, since no distinction was intended.

Store ExtFVK with encrypted Sapling spending key instead of FVK 
This ensures that even when the wallet is encrypted, we can derive the default
Sapling payment address for our spending keys.

wallet: Switch from SaplingSpendingKey to SaplingExtendedSpendingKey 
The wallet now only stores Sapling extended spending keys, and thus can
only be used with keys generated from an HDSeed via ZIP 32.

Note that not all Sapling keys in the wallet will correspond to the
wallet's HDSeed, as a standalone Sapling xsk can be imported via
z_importkey. However, it must have been generated from a seed itself,
and thus is more likely to be backed up elsewhere.

Homu 2ebde5860e Auto merge of #3326 - str4d:3058-sapling-addresses, r=str4d 
Sapling address encodings

This PR enables Sapling keys and addresses to be passed in anywhere Sprout keys
and addresses are used. Doing so will cause crashes until those places are updated
with Sapling support.

Includes code cherry-picked from the following upstream PRs:

- bitcoin/bitcoin#11167
  - Only the `ConvertBits()` function.
- bitcoin/bitcoin#11630

Closes #3058.
