James Bardin 924b97238f Handle StateFuncs in provider shim
Any state modifying functions can only be run once during the plan-apply
cycle. When regenerating the Diff during ApplyResourceChange, strip out
all StateFunc and CustomizeDiff functions from the schema.

Thew NewExtra diff field was where config data that was modified by a
StateFunc was stored, and needs to be maintained between plan and apply.

During PlanResourceChange, store any NewExtra data from the Diff in the
PlannedPrivate data, and re-insert the NewExtra data into the Diff
generated during ApplyResourceChange.

Martin Atkins 72e279e6b2 providers: Consistently use int64 for schema versions
The rest of Terraform is still using uint64 for this in various spots, but
we'll update that gradually later. We use int64 here because that matches
what's used in our protobuf definition, and unsigned integers are not
portable across all of the protobuf target languages anyway.

Justin Campbell 9a8a74b9bb plugin/discovery: Print name before verification
This is so that any errors output from the checksum/signature verification show up in the expected place in the output.

Justin Campbell 495826444b plugin/discovery: Use GPG keys from Registry
When verifying the signature of the SHA256SUMS file, we have been
hardcoding HashiCorp's public GPG key and using it as the keyring.

Going forward, Terraform will get a list of valid public keys for a
provider from the Terraform Registry (registry.terraform.io), and use
them as the keyring for the openpgp verification func.

Martin Atkins 4fe9632f09 plugin: Establish our current plugin protocol as version 5
The main significant change here is that the package name for the proto
definition is "tfplugin5", which is important because this name is part
of the wire protocol for references to types defined in our package.

Along with that, we also move the generated package into "internal" to
make it explicit that importing the generated Go package from elsewhere is
not the right approach for externally-implemented SDKs, which should
instead vendor the proto definition they are using and generate their
own stubs to ensure that the wire protocol is the only hard dependency
between Terraform Core and plugins.

After this is merged, any provider binaries built against our
helper/schema package will need to be rebuilt so that they use the new
"tfplugin5" package name instead of "proto".

In a future commit we will include more elaborate and organized
documentation on how an external codebase might make use of our RPC
interface definition to implement an SDK, but the primary concern here
is to ensure we have the right wire package name before release.

Martin Atkins ec57927ea3 build: Take protoc out of the "go generate" path
Since protoc is not go-gettable, and most development tasks in Terraform
won't involve recompiling protoc files anyway, we'll use a separate
mechanism for these.

This way "go generate" only depends on things we can "go get" in the
"make tools" target.

In a later commit we should also in some way specify a particular version
of protoc to use so that we don't get "flapping" regenerations as
developers work with different versions, but the priority here is just to
make "make generate" minimally usable again to restore the dev workflow
documented in the README.

This also includes some updates that resulted from running "make generate"
and "make protobuf" after those Makefile changes were in place.

Martin Atkins e25f79ed28 plugin/convert: Show approximate location context for all provider errors
Even if a provider doesn't indicate a specific attribute as the cause of
a resource operation error, we know the error relates to some aspect of
the resource, so we'll include that approximate information in the result
so that we don't produce user-hostile error messages with no context
whatsoever.

Later we can hopefully refine this to place the source range on the header
of the configuration block rather than on an empty part of the body, but
that'll require some more complex rework here and so for now we'll just
accept this as an interim state so that the user can at least figure out
which resource block the error is coming from.

Martin Atkins 3eaf2c308d plugin/discovery: Use mockos_mockarch when testing installation

James Bardin 0d4d572c39 start work on helper/resource test fixtures
The helper resource tests won't pass for now, as they use a
terraform.MockProvider which can't be used in the schema.Provider shims.

James Bardin 35b375d3ee check responses for nil values
While providers shouldn't return nil values, we need to protect against
them. Always assign valid null cty values when the response contains a
nil.

Martin Atkins 88551181d5 plugin: Fix tests
An earlier change made the tests not compile here. We now need to use the
legacyPluginMap function, since pluginMap has now been replaced with
helpers to produce new-style plugin _sets_.

Martin Atkins a7342de274 core: Properly handle no-op changes in plan
Previously we just left these out of the plan altogether, but in the new
plan types we intentionally include change information for every resource
instance, even if no changes are actually planned, to allow alternative
plan file viewers to show what isn't changing as well as what is.

Martin Atkins 5559d21855 plugin: Register v5 plugins only if present
Previously we would construct both provisioner and the provider objects if
either callback was set, but this is incorrect because a plugin should
actually set only one of these at a time, depending on what kind of plugin
it is.

James Bardin c07ce1cd4b move conversion functions into separate package
Managing which function need to be shared between the terraform plugin
and the helper plugin without creating cycles was becoming difficult.
Move all functions related to converting between terraform and proto
type into plugin/convert.
