Split up ATM parts of trust storage and refactor (#388)

QXmppTrustStorage is now the base class for all trust storages used by
end-to-end encryption managers.
QXmppAtmTrustStorage is used by QXmppAtmManager.

QXmppTrustMemoryStorage is now the base class for all trust storages
that use the memory for storing data.
QXmppAtmTrustMemoryStorage can be used by QXmppAtmManager.

Methods needed by the upcoming OMEMO implementation are added.
Some existing methods are refactored.
