Add keyring package

In preparation for introducing support for the new filesystem-level
keyrings, move the existing user keyring management code from
security/keyring.go and crypto/crypto.go into a new package, 'keyring'.

This package provides functions AddEncryptionKey, RemoveEncryptionKey,
and GetEncryptionKeyStatus which delegate to either the filesystem
keyring (added by a later patch) or to the user keyring.  This provides
a common interface to both types of keyrings, to the extent possible.
