This is a helper package that creates a very thin abstraction over
terminal setup, with the main goal being to deal with all of the extra
setup we need to do in order to get a UTF-8-supporting virtual terminal
on a Windows system.

The upstream bug with opening a browser on Windows Subsystem for Linux
has been fixed, so this reverts our local patch for this. The approach
upstream adds fallback support for x-www-browser and www-browser if
xdg-open fails, and this fixes the problem on WSL.

This reverts commit 12e090ce.

This is needed to make it possible to use the scram-sha-256
authentication method for the pg backend. It's not easy to write
unit-tests for this since it requires a specific configuration of the
PostgreSQL server, I did test it manually thought and everything seems
to work like it should.

Closes https://github.com/hashicorp/terraform/issues/24016

Includes fix for breaking upstream API change.

Added an Off level to hclog, so we can individually disable logging at
various levels.

Added IndependentLevels so that sublogger levels are not linked to their
parents.

We need some fixes from master.

The main process is now handling what output to print, so it doesn't do
any good to try and run it through prefixedio, which is only adding
extra coordination to echo the same data.

Update go-cmp to prevent pointer arithmetic panics when using the race
detector.

helper/copy CopyDir was used heavily in tests. It differes from
internal/copydir in a few ways, the main one being that it creates the
dst directory while the internal version expected the dst to exist
(there are other differences, which is why I did not just switch tests
to using internal's CopyDir).

I moved the CopyDir func from helper/copy into command_test.go; I could
also have moved it into internal/copy and named it something like
CreateDirAndCopy so if that seems like a better option please let me
know.

helper/copy/CopyFile was used in a couple of spots so I moved it into
internal, at which point I thought it made more sense to rename the
package copy (instead of copydir).

There's also a `go mod tidy` included.

Fixes #26175

Update tests to match the fix in mitchellh/cli#71, which aligns MockUi
with BasicUi and allows newlines in user input.

We are not using the new ErrorWriter, added in mitchellh/cli#81, as it
does not appear to interact correctly with panicwrap. All error output
from CLI parsing will continue to appear on stdout, not stderr.

go-cty v1.6.1 fixes a panic in the `element` function when called with a negative offset.

We've not been using HIL in the main codepaths since Terraform 0.12, but
some references to it (and some supporting functionality in Terraform)
stuck around due to interactions with types we'd kept around to support
legacy shims.

However, removing the configs.RawConfig field from
terraform.ResourceConfig disconnects that subtree of dependencies from
everything else, allowing us to remove it. This is safe because the only
remaining uses of terraform.ResourceConfig are shims from values that
were already evaluated using the HCL 2 API, and thus they never need
the "just in time" HIL evaluation that ResourceConfig.interpolateForce
used to do.

We also had some HIL references in configs/hcl2shim that were previously
in support of the "terraform 0.12upgrade" command, but the implementation
of that command is now removed.

There was one remaining reference to HIL in a now-unused function in the
helper/schema package, which I removed entirely here.

This then allows us to remove the HIL dependency entirely, and also to
clean up some remaining old remants of the legacy "config" package that
we'd recently moved into the "configs" package pending further pruning.

dependencies: updating Azure/azure-sdk-for-go, Azure/go-autorest, hashicorp/go-azure-helpers, tombuildsstuff/giovanni

* updating `github.com/Azure/azure-sdk-for-go` to `v45.0.0`
* updating `github.com/Azure/go-autorest` to `v0.11.3`
* updating `github.com/hashicorp/go-azure-helpers` to `v0.12.0`
* updating `github.com/tombuildsstuff/giovanni` to `v0.12.0`

This is for consistency with other commands which use prompts, all of
which require "yes" rather than "y" to confirm.

We also migrate the login command to use UIInput, which now supports
securely asking for passwords or secrets via the speakeasy library.
