4a75796117 wallet+waddrmgr: refactor to use extended key instead of seed
To allow a wallet to be created directly from an extended master root
key (xprv), we move the derivation from seed to extended key to the
loader instead of the address manager itself.

waddrmgr: use correct DerivationPath for watch-only accounts
Previously, addresses that belong to a watch-only account would have a
derivation path using the internal account number used to identify
accounts within the databse, rather than the actual account number based
on the account's master public key child index. This wasn't an issue
before as only one account would exist within the wallet, the 0 account,
which is also the default. To ensure users of the DerivationPath struct
can arrive at addresses correctly, we introduce a new field
InternalAccount to denote the internal account number and repurpose the
existing Account field to its actual meaning.

waddrmgr: convert unit tests to package-level tests
In this commit, we convert our unit tests to have package-level access.
We do this as an effort to reduce test code duplication when we
introduce migration tests which require access to specific unexported
functions/methods.

4656a00705 Improve wallet atomicity.
This changes the database access APIs and each of the "manager"
packages (waddrmgr/wstakemgr) so that transactions are opened (only)
by the wallet package and the namespace buckets that each manager
expects to operate on are passed in as parameters.

This helps improve the atomicity situation as it means that many
calls to these APIs can be grouped together into a single
database transaction.

This change does not attempt to completely fix the "half-processed"
block problem.  Mined transactions are still added to the wallet
database under their own database transaction as this is how they are
notified by the consensus JSON-RPC server (as loose transactions,
without the rest of the block that contains them). It will make
updating to a fixed notification model significantly easier, as the
same "manager" APIs can still be used, but grouped into a single
atomic transaction.

fcccae3d1a Manage wallet db namespaces from wallet package.
This changes the wallet.Open function signature to remove the database
namespace parameters.  This is done so that the wallet package itself
is responsible for the location and opening of these namespaces from
the database, rather than requiring the caller to open these ahead of
time.

A new wallet.Create function has also been added.  This function
initializes a new wallet in an empty database, using the same
namespaces as wallet.Open will eventually use.  This relieves the
caller from needing to manage wallet database namespaces explicitly.

Fixes .

d714bf3310 Refactor wallet opening.
Rather than the main package being responsible for opening the address
and transaction managers, the namespaces of these components are
passed as parameters to the wallet.Open function.

Additionally, the address manager Options struct has been split into
two: ScryptOptions which holds the scrypt parameters needed during
passphrase key derivation, and OpenCallbacks which is only passed to
the Open function to allow the caller to provide additional details
during upgrades.

These changes are being done in preparation for a notification server
in the wallet package, with callbacks passed to the Open and Create
functions in waddrmgr and wtxmgr.  Before this could happen, the
wallet package had to be responsible for actually opening the managers
from their namespaces.

8f9f53a618 Switch to new waddrmgr package
This commit converts the wallet to use the new secure hierarchical
deterministic wallet address manager package as well as the walletdb
package.

The following is an overview of modified functionality:

- The wallet must now be created before starting the executable
- A new flag --create has been added to create the new wallet using wizard
  style question and answer prompts
- Starting the process without an existing wallet will instruct now
  display a message to run it with --create
- Providing the --create flag with an existing wallet will simply show an
  error and return

In addition the snacl package has been modified to return the memory after
performing scrypt operations to the OS.

Previously a runtime.GC was being invoked which forced it to release the
memory as far as the garbage collector is concerned, but the memory was
not released back to the OS immediatley.  This modification allows the
memory to be released immedately since it won't be needed again until the
next wallet unlock.

454d290b68 Convert waddrmgr to new walletdb package.
This commit converts the waddrmgr package to use the new walletdb package
semantics.

Since waddrmgr no longer controls the database, it is unable to make a
copy of the database and return it as the old ExportWatchingOnly function
required.  As a result, it has been renamed to ConvertToWatchingOnly and
it now modifies the namespace provided to it.  The idea is that the caller
which does control the database can now make a copy of the database, get
the waddrmgr namespace in the database copy and invoke the new function
to modify it.  This also works well with other packages that might also
need to make modifications for watching-only mode.

In addition, the following changes are made:

- All places that worked with database paths now work with the
  walletdb.Namespace interface
- The managerTx code is replaced to use the walletdb.Tx interface
- The code which checks if the manager already exists is updated to work
  with the walletdb.Namespace interface
- The LatestDbVersion constant is now LatestMgrVersion since it no longer
  controls the database

d0938d817f Provide new wallet address manager package.
This commit implements a new secure, scalable, hierarchical deterministic
wallet address manager package.

The following is an overview of features:

- 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)
  - Multi-tier scalable 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

This commit only provides the implementation package.  It does not
include integration into to the existing wallet code base or conversion of
existing addresses.  That functionality will be provided by future
commits.
