This removes some qualifiers that aren't necessary (e.g. public/abstract on interfaces, private on enum constructors, final on private methods, static on nested interfaces/enums), uses Java 8 lambdas and features where that's an improvement

This CL adds transferredRegistrationExpirationTime as a TransferData field
persisted to Datastore. It's only relevant for domains, and it represents the
registration expiration time resulting from the approval of the most recent
transfer request. For pending transfers, we assume the transfer will be
server-approved, and thus in DomainTransferRequestFlow we set this field to the
existing computed value serverApproveNewExpirationTime, which is what we use
for setting up the server-approve autorenew billing event and poll message.
In DomainTransferApproveFlow we overwrite this field with the freshly computed
newExpirationTime, whereas in DomainTransferCancel/RejectFlow (and in the
implicit cancel of DomainDeleteFlow during a pending transfer) we null it out.
There are two key benefits to having this field, which are described in more
detail in b/36405140.
1) b/25084229 - it allows storage of a frozen value to back the "exDate" field
of DomainTransferResponse, which we can use to fix various errors with how
exDate display currently works.
2) b/36354434 - it allows DomainResource.cloneProjectedAtTime() to just directly
set the registrationExpirationTime to this value, without computing it de
novo, which reduces duplicated logic and ensures that the new expiration time
matches the autorenew child objects.
This CL only starts writing the field on TransferData as persisted directly on
the DomainResource itself. We'll then want to backfill the field for at
least pending transfers, whether expired or not (so we can do (2) above), but
I think we might as well backfill it for all pending and approved transfers
so that we also fix (1) even for historical transfers. And then we can start
actually reading the field for both purposes. (Note that for (1), this will
only fix synchronous transfer responses served via DomainTransferQueryFlow,
not async transfer responses served via poll messages, since these have already
been persisted with a potentially bad exDate, but I don't think it's worth a
backfill for those).
One last naming note: I chose the verbose transferredRegistrationExpirationTime
rather than the extendedRegistrationExpirationTime of DomainTransferResponse
because (as is the case in autorenew grace, or for a superuser transfer) the
new registration time isn't necessarily extended at all; it may be the same as
the pre-transfer expiration time. Also, including "registration" helps clarify
w.r.t. pendingTransferExpirationTime which refers confusingly to the expiry of
the transfer itself, rather than the domain registration.

This CL changes the domain and contact transfer flows to check the entire
TransferData on the post-transfer resource, rather than just spot-checking
certain fields. This approach provides much better code coverage - in
particular, it checks that the non-request flows (approve, cancel, reject)
don't modify the fields that they shouldn't be modifying, and that they do
actually clear out the transfer server-approve entities fields written by
the transfer request flow. It's slightly orthogonal, but I also added
testing that the server-approve entities fields are actually set in the
request flows, which was previously untested.
This is pre-work for introducing an exDate-storing field into TransferData,
by making it easier to test everywhere that exDate is set *and* unset only
in the correct places.
As part of this CL, I've introduced a TransferData.copyConstantFieldsToBuilder()
method that is like asBuilder() but instead of copying all the fields to the new
builder, it only copies the logically constant ones: losing/gaining client IDs,
the request time and TRID, and transferPeriod. This is useful both in tests but
is also used in the resolvingPendingTransfer() helper that centralizes the core
transfer resolution logic (as of [] That method has its own tests,
and in the process I removed a bunch of crufty defunct TransferData tests.

In the great flow flattening, ResourceFlowUtils grew a couple nice helpers
for rebuilding transferrable resources (Domains and Contacts) upon the
resolution of a transfer - approvePendingTransfer() and denyPendingTransfer().
Most transfer-resolving callsites use one of these two helpers, but for legacy
reasons the deletion flows (DomainDeleteFlow and DeleteContactsAndHostsAction)
were instead using the "manual" resolvePendingTransfer() method or its even more
low-level createResolvedTransferData() helper instead of denyPendingTransfer().
It's simpler to just have two options - approve and deny - so this CL inlines
createResolvedTransferData() into resolvePendingTransfer() and makes the latter
a private helper for the approve/denyPendingTransfer() public helpers.
This CL also adds sanity checks that approve/denyPendingTransfer() are called
only with the logically appropriate values of TransferStatus.

Now that transfers are always restricted to 1 year, it's unnecessary to store
extendedRegistrationYears on TransferData - it will always be equal to 1. This
simplifies logic in a few other places, e.g. RdeDomainImportAction.
I verified in BigQuery that no DomainBases exist with extendedRegistrationYears
values that aren't either null or equal to 1. At some point we should remove
the persisted fields from datastore via e.g. resaving all those domains, but
it's low priority and can wait until we have some more pressing migration.

Although the delta implies that this is actually adding code, it's
better than it looks, because some of the stuff in ContactFlowUtils
is duplicating more generic methods in ResourceFlowUtils, which
can be deleted when the domain and host flows are cut over.

This change replaces all Ref objects in the code with Key objects. These are
stored in datastore as the same object (raw datastore keys), so this is not
a model change.
Our best practices doc says to use Keys not Refs because:
* The .get() method obscures what's actually going on
- Much harder to visually audit the code for datastore loads
- Hard to distinguish Ref<T> get()'s from Optional get()'s and Supplier get()'s
* Implicit ofy().load() offers much less control
- Antipattern for ultimate goal of making Ofy injectable
- Can't control cache use or batch loading without making ofy() explicit anyway
* Serialization behavior is surprising and could be quite dangerous/incorrect
- Can lead to serialization errors. If it actually worked "as intended",
it would lead to a Ref<> on a serialized object being replaced upon
deserialization with a stale copy of the old value, which could potentially
break all kinds of transactional expectations
* Having both Ref<T> and Key<T> introduces extra boilerplate everywhere
- E.g. helper methods all need to have Ref and Key overloads, or you need to
call .key() to get the Key<T> for every Ref<T> you want to pass in
- Creating a Ref<T> is more cumbersome, since it doesn't have all the create()
overloads that Key<T> has, only create(Key<T>) and create(Entity) - no way to
create directly from kind+ID/name, raw Key, websafe key string, etc.
(Note that Refs are treated specially by Objectify's @Load method and Keys are not;
we don't use that feature, but it is the one advantage Refs have over Keys.)
The direct impetus for this change is that I am trying to audit our use of memcache,
and the implicit .get() calls to datastore were making that very hard.

The dark lord Gosling designed the Java package naming system so that
ownership flows from the DNS system. Since we own the domain name
registry.google, it seems only appropriate that we should use
google.registry as our package name.
This change renames directories in preparation for the great package
rename. The repository is now in a broken state because the code
itself hasn't been updated. However this should ensure that git
correctly preserves history for each file.
