Now instead of Use*Key a project can instead define the assembly key
in the project (genreally the common dir.pops for a project) using
the AssemblyKey property. The accepted values are Open, ECMA, MSFT,
Test.

This change allows for a repo to set the default key they want to use
for projects. In corefx we have switched the default to use the Open
key instead of the old BuildTools default of MSFT key.

As part of this update we are explicitly setting the AssemblyKey in
all the library projects (although it is really only necessary for
projects that aren't the default).

Also with this change we are updating all the new libraries that have
not yet shipped stable (compared to our 1.1 release) and making them
use the Open key. Which means that for prerelease dependencies there
might be some binary breaking changes to consume.

The following libraries ahven't shipped so there key is being
changed from MSFT to Open:
Microsoft.XmlSerializer.Generator
System.CodeDom
System.Configuration.ConfigurationManager
System.Data.Odbc
System.DirectoryServices
System.DirectoryServices.AccountManagement
System.DirectoryServices.Protocols
System.IO.Ports
System.Json
System.Memory
System.Net.HttpListener
System.Net.Mail
System.Net.ServicePoint
System.Net.WebClient
System.Net.WebProxy
System.Private.Xml
System.Private.Xml.Linq
System.Security.Cryptography.Xml
System.Security.Permissions
System.Transactions.Local
System.Web.HttpUtility

This port has skipped tests because we're blocked on some CI dependencies. See dotnet/corefx#17405.

we were bin placing the facade assemblies to the ref folder during netfx build. this was causing a problem while building the tests as we'll get some types defined in the referenced facade assemblies and core libs.

This ports the type model and C#/VB code generators to corefx; compilation to assemblies is currently not supported (we could potentially layer that on top of Roslyn subsequently).  I also ported a bunch of tests, though there's lots of room for improvement on the test suite.

This moves to a central versioning scheme for all packages that is tied
to the product release.  1.1 will include packages all with a common
version.

Updated build tools package to latest build.

Renamed BuildNumber.props to BuildValues.props and updated content to
align with changes in build tools.

Disable signing of test assemblies as it significantly increases build
time for no value.

Wired in UpdateBuildValues.targets.

Disabled several tests that are failing after moving to the 64-bit
CoreCLR package (issues 1002 and 1011).

This is to address issue dotnet/corefx#758.

This change adds BuildNumber.props containing the daily build number
property that's consumed by the package build infrastructure.

Updated package versions for Immutable and Metadata based on the values
of the daily building packages. The values have a build number one
greater than the last build.

Deleted all nuspec files for non-shipping packages.

Move src\dirs.props properties into the root, to avoid issues where setting Configuration to anything will cause the build to fail because of checks in the Microsoft common targets.

Right now, there's a mix of ToolsVersion 4.0 and 12.0 in the projects.
We should make sure that it's 12.0 everywhere.

This is the initial change to switch to using common targets across the repo.

This change adds a dir.props and dir.targets file that each project file will
import at the top and bottom of the project to default a lot of the common properties
and targets.
