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 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.

plugin: bump protocol version
We changed the type of InstanceState.Meta and this will break
pre-existing plugins. They simply have to recompile to work.

plugin: bump the protocol version due to Provisioner change 2017-01-26 15:03:27 -08:00

plugin: bump protocol version
This is necessary since the TypeUnknown HIL handling in helper/schema
makes providers compiled WITHOUT TypeUnknown incompatible with the way
core handles unknown values.

Mitchell Hashimoto 84214437b3 Use hashicorp/go-plugin for plugin system
This replaces this plugin system with the extracted hashicorp/go-plugin
library.

This doesn't introduce any new features such as binary flattening but
opens us up to that a lot more easily and removes a lot of code from TF
in favor of the upstream lib.

This will introduce a protocol change that will cause all existing
plugins to have to be recompiled to work properly. There is no actual
API changes so they just have to recompile, but it is technically
backwards incompatible.
