This generates additional metadata for the .NET Core SDK to resolve conflicts between Microsoft.AspNetCore.App and PackageReferences which contain the same assemblies.
* Replace the aspnet/JsonPatch git submodule and merge the master branch of its source to this repo
* Likewise for aspnet/DotNetTools
* And aspnet/HtmlAbstractions
* merge latest infrastructure changes from the release/2.2 branch
This removes EntityFrameworkCore as a git submodule. The EFCore repo will build on its own, and the AspNetCore repo will consume EFCore via PackageReference.
This refactors the targets used to build the shared framework and its .zip files. There are lots of reasons motivating this: Arcade convergence, migration to VSTS, making it easier to build this locally, etc.
Changes:
* Moves move content of build/Sharedfx.{props/targets} into eng/targets/SharedFx.Common.{props/targets}
* Update the build to produce a `runtime.$rid.Microsoft.AspNetCore.App` package (not just the one with symbols in it)
* Refactor the targets which produce .tar.gz/.zip files into separate projects in `src/Installers/`
* Refactor installers, unit tests, and the framework projects to use ProjectReference to flow dependencies between different parts of the build.
* Makes it easier to build the shared framework locally (for the inner dev loop, you can run `dotnet build -p src/Framework/Microsoft.AspNetCore.App/src/ -r win-x64`)
As a part of merging and reducing the number of repos we use, the aspnet/Common repo was renamed to aspnet/Extensions and it now builds on its own and not as a submodule of this repo.
This is an update of our VS dependencies to the RTM versions based on
15.8. We anticipate updating again soon in master to pick up 16.0
versions - this change is just to catch up with the current state so
there are fewer surprises.
