This commit introduces two new address types to the waddrmgr. The first address type is the native p2wkh (pay-to-witness-key-hash) output type introduced as part of BIP0141 and the segwit soft-fork. The second address type is a p2wkh output nested *within* a regular p2sh output. This second address allows older wallets which are not yet aware of the new segwit output types to transparently pay to a wallet which does support them. Additionally, using this nested p2wkh output the wallet gains both the space+transaction fee savings, as well as the malleability fixes. Both address types have been implemented as special cases of the ManagedPubKeyAddress since they share several traits, only differentiating in the signing mechanism needed, and the concrete implementation of btcutil.Address returned by the address. Two new `addressType` constants have been added to waddrmgr’s db in order to properly serialize and deserialize the new address types. |

Package waddrmgr provides a secure hierarchical deterministic wallet address manager.
A suite of tests is provided to ensure proper functionality. See
test_coverage.txt for the gocov coverage report. Alternatively, if you are
running a POSIX OS, you can run the cov_report.sh script for a real-time
report. Package waddrmgr is licensed under the liberal ISC license.
Feature Overview
- BIP0032 hierarchical deterministic keys
- BIP0043/BIP0044 multi-account hierarchy
- Strong focus on security:
- Fully encrypted database including public information such as addresses as well as private information such as private keys and scripts needed to redeem pay-to-script-hash transactions
- Hardened against memory scraping through the use of actively clearing private material from memory when locked
- Different crypto keys used for public, private, and script data
- Ability for different passphrases for public and private data
- Scrypt-based key derivation
- NaCl-based secretbox cryptography (XSalsa20 and Poly1305)
- Scalable design:
- Multi-tier key design to allow instant password changes regardless of the number of addresses stored
- Import WIF keys
- Import pay-to-script-hash scripts for things such as multi-signature transactions
- Ability to export a watching-only version which does not contain any private key material
- Programmatically detectable errors, including encapsulation of errors from packages it relies on
- Address synchronization capabilities
- Comprehensive test coverage
