When you call GetValue or GetValueAsync, it's possible that the
method may throw OperationCanceledException if you are the only
requestor and the request is cancelled during your call. In this
case we need to ensure that the token associated with the exception
is the CancellationToken that you passed in instead of the computation
token that we created.

AsyncLazy no longer calls computation functions under the lock.

Fix to VB pretty-listing of line continuation characters in interpolations.

The VB pretty-lister shouldn't remove line continuation characters after
the opening brace or before the closing brace of an interpolated string.
In addition, I found that the pretty-lister was greedily removing line
continuation characters in error conditions where a missing token was
inserted by the compiler to represent the list token of a statement.

Dual-build Microsoft.DiaSymReader -- Net20 and Portable Profile 7

This change addresses #259: below issues related to diagnostics generated for analyzer exceptions from third party analyzers.

1.Suppression of duplicate exception diagnostics: Current mechanism did the suppression in SuppressMessageState based on unique reported messages. This is obviously incorrect as an exception diagnostic will be reported non-suppressed and suppressed on subsequent queries to SuppressMessageState.IsDiagnosticSuppressed.


2.The IDE diagnostic service has multiple layers where document/project diagnostics are filtered and these analyzer exception diagnostics were getting dropped at various places.


So this change moves the exception diagnostics generation + reporting out of the regular analyzer diagnostic pipeline and in line with analyzer load failure diagnostics reporting in VS:

1.Add an event handler to AnalyzerDriverHelper to report analyzer exception diagnostics to interested clients.


2.Listen to these diagnostic events in IDE diagnostic service and wrap them with relevant workspace/project argument and generate updated events.


3.Add an AbstractHostDiagnosticUpdateSource in Features layer to listen and report analyzer exception diagnostic events from diagnostic service. Additionally, removal of an analyzer reference in workspace will clean up the diagnostics for the analyzers belonging to that analyzer reference.


4.Listen to exception diagnostic events in command line compiler and report as regular diagnostics.


Added typw AbstractHostDiagnosticUpdateSource can be extended in future to report other kind of host diagnostics which are not related to a project/document/analyzer.

Correct System.Windows.Forms.dll casing

update version when factory is removed in error list

this should make deleted error cleanup faster then now in error list

Improve LargeEncodedText performance.

Includes the following public API changes:

Source
 1. Source that extends SourceText and attempts to override the Lines property will now fail to compile.
 2. Source that called SourceText.From(Stream) will continue to compile but will silently call a new overload with a default value which preserves the current behavior.

Binaries
 1. Binaries that extended SourceText and override the Lines property will now fail at runtime when running against the next version of Microsoft.CodeAnalysis.dll
 2. Binaries that call SourceText.From(Stream) will fail at runtime with MissingMethodException when running against the next version of Microsoft.CodeAnalysis.dll

Rename HasAccessChecksSuppressed to IgnoresAccessibility

Format hash directives inside other hash directives of complex trivia

Don't filter out zero length tag spans in the async tagger architecture.

Add common Boxes to Microsoft.CodeAnalysis

Change SyntaxEditor.InsertAfter to call correct overload.

Fix spelling: supress -> suppress

1) Make LocalizableString implement IEquatable<LocalizableString> to ensure Diagnostic equality works as expected for Descriptor based diagnostics.
2) Additionally, also refactor code a bit more to move register/unregister code for analyzer exception diagnostics down to the core AnalyzerDriverHelper.
3) Fix test failures.

Prevent CodeActions commits during Inline Rename

Fix #554: This fixes a crash that was caused by invoking a lightbulb
item that caused an Inline Rename session to launch when there's already
an inline rename session active. We now check for inline rename sessions
during lightbulb commit. If an inline rename session is active, we halt
the lightbulb commit and tell the user to complete their rename session.

This only prevents one (but probably the most frequent) manifestation of
a larger problem in which rename is trying to perform a series of
changes to the workspace that can be interrupted by some other feature
applying its changes to the workspace. This larger design problem is
tracked as #681.
