Prepare migrating testing auxiliary functions from tests
to testutil.
Remove local duplicates on testutil.WriteToNewTempFile().
Always favor testutil.NewTestCaseDir() over ioutil.TempDir().
Add test cases for the testing auxiliary functions.
crypto/keyring:
`Keybase` interface gives way to its successor: `Keyring`. `LegacyKeybase`
interface is added in order to guarantee limited backward compatibility with
the old `Keybase` interface for the sole purpose of migrating keys across
the new keyring backends.
The package no longer depends on the `github.com/types.Config`
singleton.
`SupportedAlgos` and `SupportedLedgerAlgos` methods have been removed.
The keyring just fails when trying to perform an action with an unsupported
algorithm.
crypto/ subdirs reorganization:
`crypto/keys/hd` was moved to `crypto/hd`, which now groups together
all HD wallets related types and utilities.
client/input:
* Removal of unnecessary `GetCheckPassword`, `PrintPrefixed` functions.
* `GetConfirmation`'s signature changed to take in a io.Writer for better integration
with `cobra.Command` types.
client/context:
* In-memory keyring is allocated in the context when `--gen-only` flag is passed
in. `GetFromFields` does no longer silently allocate a keyring, it takes one as
argument.

Remove the Update method from the Keybase interface.
Remove redundant lazy keybase implementation altogether.
Created LegacyKeybase interface to restrict capabilities to
only those required by keys commands that deal with
legacy keybase such as update and migrate.
Rename keyring.New() -> keyring.NewLegacy().
Rename client/keys.NewKeyBaseFromDir -> NewLegacyKeyBaseFromDir.
crypto/keyiring.NewInMemory() now returns a in-memory keyring.
BackendMemory is added yet not exposed via command line
--keyring-backend flag. keys add uses it when --dry-run flag
is on.
