Merge #12924: Fix hdmaster-key / seed-key confusion (scripted diff)

6249021d1 [docs] Add release notes for HD master key -> HD seed rename (John Newbery)
79053a5f2 [rpc] [wallet] Add 'hdmasterkeyid' alias return values. (John Newbery)
c75c35141 [refactor] manually change remaining instances of master key to seed. (John Newbery)
131d4450b scripted-diff: Rename master key to seed (John Newbery)

Pull request description:

  Addresses #12084 and #8684

  This renames a couple of functions and members (no functional changes, expect log prints):

  - Rename CKey::SetMaster to CKey::SetSeed
  - Rename CHDChain::masterKeyId to CHDChain::seedID
  - Rename CHDChain::hdMasterKeyID to CHDChain::hdSeedID
  - Rename CWallet::GenerateNewHDMasterKey to CWallet::GenerateNewHDSeed
  - Rename CWallet::SetHDMasterKey to CWallet::SetHDSeed

  As well it introduces a tiny API change:

  - RPC API change: Rename "hdmasterkeyid" to "hdseedid", rename "hdmaster" in wallet-dump output to "hdseed"

  Fixes also a bug:

  - Bugfix: use "s" instead of the incorrect "m" for the seed-key hd-keypath key metadata

+RPC changes
+------------
+
+### Low-level changes
+
+- The `getwalletinfo` RPC method now returns an `hdseedid` value, which is always the same as the incorrectly-named `hdmasterkeyid` value. `hdmasterkeyid` will be removed in V0.18.
+- The `getaddressinfo` RPC method now returns an `hdseedid` value, which is always the same as the incorrectly-named `hdmasterkeyid` value. `hdmasterkeyid` will be removed in V0.18.
+
+Other API changes
+-----------------
+
+- The `inactivehdmaster` property in the `dumpwallet` output has been corrected to `inactivehdseed`
