Allow ext keys (#3)
Browse files Browse the repository at this point in the history 
* rpc/deriveaddress: Add support for sp desc

* spscriptpubkeyman: Move labelled destination generation to seperate methods

* rpc/getnewaddress: Add silent-payment to addess_type list

* descriptor: Allow extended keys in sp()

* Fix scan key storage issues in watch only wallet

- Stop adding scan key to singingprovider private key map, this will prevent scan key from being counted among private keys
- Stop storing scan keys to db, scan keys are already saved in descriptor

* spscriptpubkeyman: Fix MarkUnusedAddresses SegFault

DescriptorScriptPubKeyMan::MarkUnusedAddresses tries to expand the descriptor and read the resulting scripts
This does not work for sp descriptors as no scripts are returned
This leads to a SegFault

* test: Add E2E test for sp descriptor
