2021-08-23Consolidate XOnlyPubKey lookup hackAndrew Chow
The places where we need to lookup information for a XOnlyPubKey currently implement a hack which makes both serializations of the full pubkey in order to try the CKeyIDs for the lookup functions. Instead of duplicating this everywhere it is needed, we can consolidate the CKeyID generation into a function, and then have wrappers around GetPubKey, GetKey, and GetKeyOrigin which takes the XOnlyPubKey, retrieves all of the CKeyIDs (using the new GetKeyIDs() function in XOnlyPubKey), and tries their respective underlying lookup function.

This is not very user friendly as normalized descriptors shouldn't require and don't involve the private keys except for derivation. We solve this problem by caching the last hardened xpub (which has to be derived at some point when generating the address pool). However the last hardened xpub was not already being cached. We only cached the immediate parent xpub and derived child keys. For example, with a descriptor derivation path of `/84'/0'/0'/0/*`, the parent xpub that is cached is `m/84'/0'/0'/0`, and the child keys of `m/84'/0'/0'/0/i` (note that child keys would not be cached in this case). This parent xpub is not suitable for the normalized descriptor form as we want the key at `m/84'/0'/0'`. So this PR adds another field to `DescriptorCache` to cache the last hardened xpub so that we can use them for normalized descriptors. Since `DescriptorCache` is changing, existing descriptor wallets need to be upgraded to use this new cache. The upgrade will occur in the background either at loading time (if the wallet is not encrypted) or at unlocking time in the same manner that `UpgradeKeyMetadata` operates. It will use a new wallet flag `WALLET_FLAG_LAST_HARDENED_XPUB_CACHED` to indicate whether the descriptor wallet has the last hardened xpub cache. Lastly `listdescriptors` will not require the wallet to be locked and `getaddressinfo`'s `parent_desc` will always be output (assuming the upgrade has occurred).
