Although we do still consider these deprecated for 0.12, we'll defer
actually generating warnings for them until a later minor release so that
module authors can retain their quoted identifiers for a period after 0.12
release for backward-compatibility with Terraform 0.11.
The error-handling behavior of the HCL parser was improved, which causes
the number of diagnostics and the diagnostics messages to be different
in cases where a block-like introduction is given but without any
following body.
This is largely minor bugfixes for issues found since we last updated the
vendoring. There are some new features here that Terraform is not yet
using and thus present little risk.
In particular this includes the HCL-JSON spec change where arrays can now
be used at any level in a block label structure, to allow for preserving
the relative order of blocks.
While not normally possible, manual manipulation of the state and config
can cause us to end up with a nil config in
evalTreeManagedResourceNoState.
Regardless of how it got here, we can't ever assume the Config field is
not nil, and EvalInterpolate happily accepts a nil RawConfig
Also:
- In the getting started guide, the TFE content was all tailored to the older
run-locally workflow. I've replaced it with some brief explanation and a link
to the dedicated TFE getting started guide.
- Fixed a sidebar link glitch in the configuration section. (Both "Terraform"
and "Terraform Enterprise" were marked as active if you were on the TFE page.)
- Renamed the "Terraform Enterprise" page "Terraform Push." (Some people have
gotten confused and landed on this page when trying to set up the `atlas`
remote backend.)

Use the new StateLocker field to provide a wrapper for locking the state
during terraform.Context creation in the commands that directly
manipulate the state.
Simplify the use of clistate.Lock by creating a clistate.Locker
instance, which stores the context of locking a state, to allow unlock
to be called without knowledge of how the state was locked.
This alows the backend code to bring the needed UI methods to the point
where the state is locked, and still unlock the state from an outer
scope.
Provide a NoopLocker as well, so that callers can always call Unlock
without verifying the status of the lock.
Add the StateLocker field to the backend.Operation, so that the state
lock can be carried between the different function scopes of the backend
code. This will allow the backend context to lock the state before it's
read, while allowing the different operations to unlock the state when
they complete.

Use the new StateLocker field to provide a wrapper for locking the state
during terraform.Context creation. We can then remove all the state
locking code from individual operations, and unlock them in one place
inside the main Operation method.
Add the StateLocker field so that the state lock can be carried between
the different function scopes of the backend code. This will allow the
backend context to lock the state before it's read, while allowing the
different operations to unlock the state when they complete.
