removed serializedSolution/Project/DocumentInfo and rolled them into …

This reverts commit 720f5c5e, reversing
changes made to 6a6043c3.

changes include
make SourceText::GetChecksum and AnalyzerTelemetry contructor public.

added MustRunInProc in IBuiltInAnalyzer and some clean up around serializing Solution/Project/DocumentId and how DocumentState is exposed.

simplified temporary storage service's temporary storage management and added ability to attach to existing temporary storage

solution checksum and serialization service.

added remote host client
- this gives an ability for host (vs) to talk to remote host (service hub)

rename and moving files between feature/workspace layers
- only real change is having ICompilerDiagnosticAnalyzer interface which can either have inproc implementation or out of proc implementation.
- inproc is needed since diagnostics are in feature layer and one who uses feature layer out side of VS host need an implementation.

added RemoteWorkspace
- RemoteWorkspace has host agnostic implementation of roslyn features/services/workspace that will run in remote host

added service hub component and setup project for service hub
- service hub component is basically thin layer that deals with converting data to pass in to RemoteWorkspace

made devdiv insertion tool to ignore servicehub related files

support byte and char array natively in ObjectReader/Writer

added MustRunInProc in IBuiltInAnalyzer and some clean up around serializing Solution/Project/DocumentId and how DocumentState is exposed.

closes #915
closes #1571

Binary serialization is not supported in CoreCLR and hence must be removed
from the subset which runs there.  This code is only used to support
CodeLens so rather than moving it around we are simply removing it
completely.  It will be relocated to CodeLens internally to continue supporting
their scenarios.

The Public API changes to DocumentId and ProjectId were necessary to
continue supporting serialization outside of the Roslyn code base.

closes #915

     Background:

     As discussed in the dev team all hands all code under the GitHub dotnet foundation is using a single process for contribution, API review, infrastructure and coding style. The idea is to present a unified view to our customer and give them a single story for contributing to any project under the dotnet foundation.

     https://github.com/dotnet/corefx/wiki/Contributing#c-coding-style

     The coding style transition is automated using a Roslyn based rewrite tool:

     https://github.com/dotnet/codeformatter

     This will be applied in stages across our developer tree. Right now the focus is on the Open directory as this is what is being presented on github. Code owners will be contacted before the transition happens.

     Note: this is a soft style requirement. There are no build errors that come from this change.

Provide serializable wrappers of DocumentId, ProjectId and VersionStamp. This mirrors the SerializableProjectReference that was already in Workspaces.Desktop (and public), and the serializable wrappers of various compiler types. (changeset 1352515)

This change splits the Workspaces layer into two parts, mirroring the Portable/Desktop split that the compilers did. The core parts of the Workspaces layer (managing documents and projects, formatting, some refactoring, code fixes) is kept in the portable subset, with a few non-portable pieces remaining, notably MSBuild support.

This change has a major impact on how MEF now works in Roslyn. Traditional MEF (“MEFv1”) is not portable, and so we must move the Workspaces layer over to using the Microsoft.Composition NuGet package (“MEFv2”) which is. The APIs are distinct in that each has its own namespace, but the concepts are more or less identical. It requires some care though: the workspaces layer is simple in that it only references MEFv2, but higher layers have to reference both versions to use metadata attributes. Exports using metadata attributes from the editor (say, ContentTypeAttribute) must use MEFv1 attributes to export, whereas exports for the workspaces layer must use MEFv2 attributes. The rule is subtle and yet simple, and so a diagnostic is provided which catches any offenses to prevent confusion.

This also has some impact in how we create MEF hosts: if you wish to host just the base workspaces layer, we can use MEFv2 to compose everything. The HostServices implementation (MefV1HostServices) that consumes a MEFv1 ExportProvider. If you’re in Visual Studio, you can use this implementation to get the full set of host services provided in Visual Studio.

Otherwise, most of the changes in here are minor: we react to some APIs that have been moved/renamed in the portable subset we are targeting, and also align our various exception helper utilities with the compiler’s precedent. (changeset 1349276)
