Alisdair McDiarmid 9a9f4e2696 configs: Fix provider requirements panics
When parsing provider requirements we should check the type of the
source and version attributes rather than assuming that they are
strings. Otherwise an invalid attribute value will cause a panic.

configs: require normalized provider local names (#24945)
* addrs: replace NewLegacyProvider with NewDefaultProvider in ParseProviderSourceString

ParseProviderSourceString was still defaulting to NewLegacyProvider when
encountering single-part strings. This has been fixed.

This commit also adds a new function, IsProviderPartNormalized, which
returns a bool indicating if the string given is the same as a
normalized version (as normalized by ParseProviderPart) or an error.
This is intended for use by the configs package when decoding provider
configurations.

* terraform: fix provider local names in tests

* configs: validate that all provider names are normalized

The addrs package normalizes all source strings, but not the local
names. This caused very odd behavior if for e.g. a provider local name
was capitalized in one place and not another. We considered enabling
case-sensitivity for provider local names, but decided that since this
was not something that worked in previous versions of terraform (and we
have yet to encounter any use cases for this feature) we could generate
an error if the provider local name is not normalized. This error also
provides instructions on how to fix it.

* configs: refactor decodeProviderRequirements to consistently not set an FQN when there are errors

Alisdair McDiarmid ae98bd12a7 command: Rework 0.13upgrade sub-command
This commit implements most of the intended functionality of the upgrade
command for rewriting configurations.

For a given module, it makes a list of all providers in use. Then it
attempts to detect the source address for providers without an explicit
source.

Once this step is complete, the tool rewrites the relevant configuration
files. This results in a single "required_providers" block for the
module, with a source for each provider.

Any providers for which the source cannot be detected (for example,
unofficial providers) will need a source to be defined by the user. The
tool writes an explanatory comment to the configuration to help with
this.

Alisdair McDiarmid 7ca7b1f0fe configs: Simplify required_providers blocks
We now permit at most one `required_providers` block per module (except
for overrides). This prevents users (and Terraform) from struggling to
understand how to merge multiple `required_providers` configurations,
with `version` and `source` attributes split across multiple blocks.

Because only one `required_providers` block is permitted, there is no
need to concatenate version constraints and resolve them. This allows us
to simplify the structs used to represent provider requirements,
aligning more closely with other structs in this package.

This commit also fixes a semantic use-before-initialize bug, where
resources defined before a `required_providers` block would be unable to
use its source attribute. We achieve this by processing the module's
`required_providers` configuration (and overrides) before resources.

Overrides for `required_providers` work as before, replacing the entire
block per provider.

terraform: provider source test (#24342)
* configs: parse provider source string during module merge

This was the smallest unit of work needed to start writing provider
source tests!

* Update configs/parser_test.go

configs: added map to configs.Module for provider local name lookup (#24039)
* configs: added map of ProviderLocalNames to configs.Module

We will need to lookup any user-supplied local names for a given FQN.
This PR adds a map of ProviderLocalNames to the Module, along with
adding tests for this and for decodeRequiredProvidersBlock.

This also introduces the appearance of support for a required_provider
"source" attribute, but ignores any user-supplied source and instead
continues to assume that addrs.NewLegacyProvider is the way to go.
