... but not yet enabled, because we haven't changed netci.groovy to pass the /buildTimeLimit parameter to cibuild.cmd

... but it always writes the dump, even when the process does *not* time out, because we specified "-t" on the command line. But if we don't specify "-t", we don't get a dump even when we terminate the process. What to do?

Also:
o Changed name of "timespan" argument to "time-limit"

Also:
* Change some variable names
* Improve some messages

These were accidentally changed to UTF-16LE during a recent scripted change.  This went unnoticed because the encoding change didn't register in CodeFlow (indeed if you view a shelve of this change in CodeFlow it will report no changes).  UTF-16 does not work well with Git as it is often interpreted as a binary file.  Moving back to UTF-8 so our GitHub experience works well for customers.

closes #66 (changeset 1403787)

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.

Splits Microsoft.CodeAnalysis, Microsoft.CodeAnalysis.CSharp and Microsoft.CodeAnalysis.VisualBasic into portable and desktop assemblies.

Existing Core\Source, CSharp\Source and VisualBasic\Source directories are renamed to Core\Portable, CSharp\Portable and VisualBasic\Portable.
New sibling Desktop folders are added and non-portable source is moved there.
"System.Runtime" references has to be removed in order for the portable project system magic to automatically add facade references.
