This change moves powershell to .NET Core 2.0. Major changes are:
1. PowerShell assemblies are now targeting `netcoreapp2.0`. We are using `microsoft.netcore.app-2.0.0-preview1-001913-00`, which is from dotnet-core build 4/4/17. We cannot target `netstandard2.0` because the packages `System.Reflection.Emit` and `System.Reflection.Emit.Lightweight`, which are needed for powershell class, cannot be referenced when targeting `netstandard2.0`.
2. Refactor code to remove most CLR stub types and extension types.
3. Update build scripts to enable CI builds. The `-cache` section is specified to depend on `appveyor.yml`, so the cache will be invalidated if `appveyor.yml` is changed.
4. Ship `netcoreapp` reference assemblies with powershell to fix the issues in `Add-Type` (#2764). By default `Add-Type` will reference all those reference assemblies when compiling C# code. If `-ReferenceAssembly` is specified, then we search reference assemblies first, then the framework runtime assemblies, and lastly the loaded assemblies (possibly a third-party one that was already loaded).
5. `dotnet publish` generates executable on Unix platforms, but doesn't set "x" permission and thus it cannot execute. Currently, the "x" permission is set in the build script, `dotnet/cli` issue [#6286](https://github.com/dotnet/cli/issues/6286) is tracking this.
6. Replace the use of some APIs with the ones that take `SecureString`.
7. osx.10.12 is required to update to `netcoreapp2.0` because `dotnet-cli` 2.0.0-preview only works on osx.10.12.
8. Add dependency to `System.ValueTuple` to work around a ambiguous type identity issue in coreclr. The issue is tracked by `dotnet/corefx` [#17797](https://github.com/dotnet/corefx/issues/17797). When moving to newer version of `netcoreapp2.0`, we need to verify if this dependency is still needed.
- FullCLR build is disabled in this change.
- FullCLR build related functionalities in `build.psm1` and `AppVeyor.psm1` are disabled. They are not cleaned up from `build.psm1` and `AppVeyor.psm1` yet. We need to adopt .NET Core 2.0 to verify the portable module concept, and if that works well, we will remove the Windows PowerShell source code and clean up our scripts.
- `dnxcore50` and `portable-net5+win8` target framework monikers are removed.
- Dependency on `Microsoft.NETCore.Portable.Compatibility` is removed. It's not necessary, but it may come back when we work on supporting the `portable module`. Its necessity can be reviewed at that time.
- I didn't spend the time to try building powershell in Visual Studio 2017. We should have a separate issue for that. It's tracked by #3400
The `TypeCatalogParser` project is replaced by a MSBuild target to gather the dependency information.
Due to .NET Core SDK issue [#1021](https://github.com/dotnet/sdk/issues/1021), our meta-package project `Microsoft.PowerShell.SDK` starts to generate an empty assembly during the build and that results in an empty assembly `Microsoft.PowerShell.SDK.dll` appear in `publish` folder and in `.deps.json` file. We cannot simply remove the assembly because it's now part of the TPA, and removing it will cause powershell to crash at startup. We have to live with this empty assembly until that .NET Core SDK issue is fixed. It's tracked by #3401.
* Initial support for Fedora 24
This commit adds initial support for the Fedora distribution,
starting with Fedora 24.
Whereever possible, build tooling for CentOS has been reused.
Until the next release of PowerShell is compiled against .NET 1.1,
the Docker release image uses the CentOS 7 build, but loads
in the CentOS 7 version of `libicu50` via LD_LIBRARY_PATH.
* Update Dockerfile
Fix typos
* Initial support for Fedora 24

* Update Dockerfile
Fix typos
* Rebase onto .NET Core 1.1
Modify `Build.psm1` and `project.json` files to use .NET Core 1.1.
.NET Core 1.1 ships with an older dotnet/cli than has currently been used,
so we revert to use case-sensitive directory names for dependencies.
.NET Core 1.1 is a pre-requisite for supporting Fedora 24.
* PSReadLine: Bump major version of PSReadline to 6.0.0-*
* Microsoft.PowerShell.Commands.Utility: Bump major version of Microsoft.CodeAnalysis.Csharp
* Microsoft.PowerShell.SDK: Revert attempt to import netcoreapp1.1 instead of dnxcore
* build.psm1: Restore ability to specify version of dotnet-install.sh
* Fixes#2534 by replacing expensive WMI query with Win32 API calls
* fix break on unix build
* added tests for #2535
* although test passed, fixing exception that shows up
* fixed Describe text
* addressing code review feedback
* addressing review feedback to comment on why sleep is needed
added check that test processes are created before we try to kill them
* fixed test to timeout and pending fix for #2561
