removed dead code. code I wrote long time ago for specific indenter case is left in code base when it is no longer needed.

fix vsct file to not have dupliate button definitions

Add MetadataVisualizer project to Roslyn solutions

disable some tests due to interface tests.

these tests will be re-enabled once we patch build machine with new interfaces.

Conflicts:
	src/Roslyn.sln

Replace nonbreaking space (0xA0) with a regular space.

It is likely the character was inserted by accident. There is no reason
to use it in the code. It is a valid Unicode whitespace, but not a valid
ASCII. Since the containing file has no encoding bytemarks, the behavior
of this char is dependent on default encoding. Indeed, the file compiles
on Windows and fails on Linux.
As far as I could find, this is the only case where this character is
used in actual code (not in tests) in Roslyn codebase.

Remove cancellation token from NavigateTo

Delete our copy of IsBuiltInRuleSet

Fix #308 and #306 - issues with dynamic expressions in string interpolation

NavigateTo doesn't support cancellation when computing the display properties so the cancellation token is getting removed rather than having to manually handling OperationCanceledException.

Ensure that FileKey's timestamp is Utc by adding a Debug.Assert
Use LastWriteTimeUtc in MetadataCache.

This change deletes code we use to determine if a rule set file is one
that shipped with VS, and thus cannot be modified or deleted. It was
largely copied from code in
Microsoft.VisualStudio.CodeAnalysis.Sdk.UI.dll, and we should just use
the original instead.

Fix #323 bug in SemanticModel.GetAwaitExpressionInfo when await expression used as an expression statement.

Add the CodeAnalysis analyzers projects back to the Roslyn solution.

Fix #323 bug in SemanticModel.GetAwaitExpressionInfo when await expression used as an expression statement.

It looks like this got lost when the new open Roslyn.sln was created.

Corrected documentation on FullSpan and Span

Small fixes for running suites

The BuildAndTest.proj was failing because a number of our suites aren't
correct when run in parallel.  Disabling them for now and letting #321
track reenabling them.

Enable more suites

The AppDomain loading issue was the root cause of many of the failures
which caused these suites to be disabled.  Now that the bug is fixed we
can move to running these suites again.

Fix Jenkins run

Disabling the HandleSolutionProjectTypeSolutionFolder test as it is
failing in Jenkins.  Filed issue #317 to track this test.

Fix Roslyn.sln build

This makes the necessary changes to allow for Roslyn.sln to build from
the command line.

[git-commit-sha: 10660496] (changeset 1412156)

A bit of cleanup of assembly signing interop interfaces making the code portable. (changeset 1412135)

Fixes a crash while generating debug information for a compilation with two metadata references that represent the same assembly, first with no aliases and second with an alias.   (changeset 1412130)

There are cases where underlying platform does not provide signing services in the form that we consume. We need to be able to handle such cases gracefully without crashes.
