Sander van Harmelen a7b8cc8fe3 Do not clear out a previous set state when refreshing
In the case when no state existed remotely and a new one was created locally, we don’t want to blow away the new local state when refreshing.

Martin Atkins 72a7947cb7 state/remote: Un-stub TestStateRace
The underlying bug that was causing this test to hang has since been
fixed.

Martin Atkins 78f1d1d1c0 state/remote: Don't hang in PersistState
We were calling from PersistState into RefreshState, but RefreshState is
protected by the same lock as PersistState and so the call would deadlock.

Instead, we introduce a new entry point refreshState which can be used
when already holding the lock.

Martin Atkins 477ea0d360 state/remote: Make tests compile and run to completion
One of the tests was hanging, so for now it's stubbed out until we can
get to the bottom of the hang on a subsequent pass.

Martin Atkins 4bdaffb586 state: Remove tests for obsolete components
Most of the functionality in this package has been obsoleted by equivalent
symbols in states/statemgr. We're keeping this package around for the
moment mainly just to house the type aliases in state.go.

The tests in here no longer work because they are written against the old
APIs. We will eventually remove the components these are testing too, but
we're keeping them around for the moment so that we don't break the build
for some leftover callers that are still depending on these.

Martin Atkins aaf405b662 backend/remote-state: Get all the backend tests building again
The state manager refactoring in an earlier commit was reflected in the
implementations of these backends, but not in their tests. This gets us
back to a state where the backend tests will compile, and gets _most_ of
them passing again, with a few exceptions that will be addressed in a
subsequent commit.

Martin Atkins a3403f2766 terraform: Ugly huge change to weave in new State and Plan types
Due to how often the state and plan types are referenced throughout
Terraform, there isn't a great way to switch them out gradually. As a
consequence, this huge commit gets us from the old world to a _compilable_
new world, but still has a large number of known test failures due to
key functionality being stubbed out.

The stubs here are for anything that interacts with providers, since we
now need to do the follow-up work to similarly replace the old
terraform.ResourceProvider interface with its replacement in the new
"providers" package. That work, along with work to fix the remaining
failing tests, will follow in subsequent commits.

The aim here was to replace all references to terraform.State and its
downstream types with states.State, terraform.Plan with plans.Plan,
state.State with statemgr.State, and switch to the new implementations of
the state and plan file formats. However, due to the number of times those
types are used, this also ended up affecting numerous other parts of core
such as terraform.Hook, the backend.Backend interface, and most of the CLI
commands.

Just as with 5861dbf3fc49b19587a31816eb06f511ab861bb4 before, I apologize
in advance to the person who inevitably just found this huge commit while
spelunking through the commit history.

James Bardin a84b4a669a use the open state file for refresh when possible
Only open a new file descriptor for RefreshState if we haven't written a
state, and don't have the correct state open already. This prevents
windows from failing to refresh a locked state.

James Bardin e10a7917e6 add failing test for windows state locks
Refreshing a locked state on windows could return nil if the read path
was locked, no state was yet written, and the read path is the same as
the write path.

Add a test that locks then refreshes a newly initialized state struct.

stack72 1fd0f803e4 Migrate Manta Remote state to be a backend
This PR changes manta from being a legacy remote state client to a new backend type. This also includes creating a simple lock within manta

This PR also unifies the way the triton client is configured (the schema) and also uses the same env vars to set the backend up

It is important to note that if the remote state path does not exist, then the backend will create that path. This means the user doesn't need to fall into a chicken and egg situation of creating the directory in advance before interacting with it

Update all references to the version values to use the new package.
The VersionString function was left in the terraform package
specifically for the aws provider, which is vendored. We can remove that
last call once the provider is updated.

Martin Atkins c12d64f340 Use t.Helper() in our test helpers
Go 1.9 adds this new function which, when called, marks the caller as
being a "helper function". Helper function stack frames are then skipped
when trying to find a line of test code to blame for a test failure, so
that the code in the main test function appears in the test failure output
rather than a line within the helper function itself.

This covers many -- but probaly not all -- of our test helpers across
various packages.

James Bardin 32ae05c342 fix strict remote.State lineage check
We can't check lineage in the remote state instance, because we may need
to overwrite a state with a new lineage. Whil it's tempting to add an
optional interface for this, like OverwriteState(), optional interfaces
are never _really_ optional, and will have to be implemented by any
wrapper types as well.

Another solution may be to add a State.Supersedes field to indicate that
we intend to replace an existing state, but that may not be worth the
extra check either.

James Bardin fba5decae5 update TestState helper
In practice, States must all implement the full interface, so checking
for each method set only leaves gaps where tests could be skipped.
Change the helper to only accept a full state.State implementation.

Add some Lineage, Version, and TFVersion checks to TestState to avoid
regressions.

Compare the copy test against the immediate State returnedm rather than
our previous "current" state.

Check that the states round-trip and still marhsal identically via
MarshalEqual.

Martin Atkins 4d53eaa6df state: more robust handling of state Serial
Previously we relied on a constellation of coincidences for everything to
work out correctly with state serials. In particular, callers needed to
be very careful about mutating states (or not) because many different bits
of code shared pointers to the same objects.

Here we move to a model where all of the state managers always use
distinct instances of state, copied when WriteState is called. This means
that they are truly a snapshot of the state as it was at that call, even
if the caller goes on mutating the state that was passed.

We also adjust the handling of serials so that the state managers ignore
any serials in incoming states and instead just treat each Persist as
the next version after what was most recently Refreshed.

(An exception exists for when nothing has been refreshed, e.g. because
we are writing a state to a location for the first time. In that case
we _do_ trust the caller, since the given state is either a new state
or it's a copy of something we're migrating from elsewhere with its
state and lineage intact.)

The intent here is to allow the rest of Terraform to not worry about
serials and state identity, and instead just treat the state as a mutable
structure. We'll just snapshot it occasionally, when WriteState is called,
and deal with serials _only_ at persist time.

This is intended as a more robust version of #15423, which was a quick
hotfix to an issue that resulted from our previous slopping handling
of state serials but arguably makes the problem worse by depending on
an additional coincidental behavior of the local backend's apply
implementation.
