The dependency projects were added as a way to help unify our project.json references.  Instead of every project referencing the NuGet package, we had a dependency project which referenced it and everyone referenced that dependency project.  Due to the transitive nature of NuGet it would be roughly equivalent.

This system had a number of downsides:

1. There was no enforcement.  Even though dependency projects existed, there was no mechanism to force developers to use them.
2. Getting the granularity correct was tricky.
3. The projects themselves have special props / targets to get them to produce no output.  This can trip up MSBuild up to date checks.

Since then though we've begun using RepoUtil to verify our NuGet reference correctness.  This removed the need for these projects and hence I'm removing them from our build.

Create a custom Rename-File code operation so that we don't show a very unhelpful 'full file added' preview.

Preserve modifiers when extracting out a nested type.

Always make suggestion tags two characters.

Merge dev15-rc2 into master

Create a custom Rename-File code operation so that we don't show a very unhelpful 'full file added' preview.

Do not offer 'inline declaration' if it would break scoping.

Fix fallback encoding case; canBeEmbedded was not propogated

Extend RepoUtil so it can support our internal repo

added a test for https://github.com/dotnet/roslyn/issues/14878

Our internal repo uses dotnet/roslyn as a submodule.  It has additional project.json entries that need to go through the same verification as dotnet/roslyn.  This updates RepoUtil so it can handle this structure.  In particular having the configuration file and generation files be in non-standard locations.

Account for bad commit missing

Make the GoToDefinitionHelper sit on top of the new FindUsages presenter

Move helpers to common layer.

Expose array sizes/lower bounds and type arguments custom modifiers in public API.

Allow clients to specify the behavior they want on hidden locations.

Add extension to test if a document is generated or not.

Add required reference to project.
