Display a tooltip for hyperlinks in error list and preview pane

Display a tooltip containing url destination for hyperlinks in the error list and light bulb preview pane UIs.

Also use full fidelity (i.e. substituted)  error message in the search query in the case of hyperlinks that redirect to bing search so that we can present more relevant search results.

Replace CreateStreamOnHGlobal with a custom COM Memory Stream

Fix internal bug 1138938: Keyword highlighting is unnoticeable in dark theme

The issue was that keyword highlighting was using brace highlighting tag
instead of reference highlighting tag (my guess is because brace
highlighting and keyword highlighting were written before reference
highlighting).

This change uses the reference highlighting tag. I also renamed the
keyword lighting folder structure to be called KeywordHighlighting
instead of just Highlighting.

I made a struct into a class (in 0d415c29) but I missed a null check
around an existing member access.

Dont generate Getter/Setter when Writeonly/Readonly for VB Properties

Use a custom IStream implementation rather than the native CreateStreamOnHGlobal

Change named pipe ownership check

Update Edit and Continue analyzers to use resource strings

Fix #1853 update UnitTests to use resource strings
Fix #1338 update EnC analyzers to use resource strings

- Shared the same strings in FeaturesResources
- Added "Locked" annotation not to be localized

The goal is to have a single csc.exe / vbc.exe binary that runs cross
plat and cross runtime (mono, desktop, coreclr).  Yet there are certain
features which only light up in a subset of the scenarios.  For example
the compiler server only lights up on Windows platforms.

This is fine but forces us to jump through hoops when doing platform
specific actions like checking the owner of the other end of the named
pipe.  To compile this code into a portable assembly we either need to
a) pinvoke or b) use reflection.  In this case reflection was the
simpler route.

Make Formatter.GetFormattedTextChanges public

Expose overloads of Formatter.GetFormattedTextChanges that correspond to
the overloads of Formatter.Format.

Reduce both methods to a single internal implementation and remove
optional parameters from them.

Use SpecializedCollections.SingletonEnumerable when calling Format and
GetFormattedTextChanges.

Fixes #778.

Some people found this confusing, and it's no longer accurate since we
format with parse errors now.

Provide an overload of Solution.GetCompilationAsync that takes a Project

Many entries come through Project.GetCompilationAsync, which immediately
turns around and gets the project again to call SupportsCompilation.
Provide an overload that just takes the project directly to skip the
GetProject call in the middle.

Fixes #1220.

fixed WpfTextView leak

we leaked a TextView and whole bunch of things that got put into its property bags and corresponding text buffer's property bags.

I am not 100% sure whether this is new or root cause of our VM regression but regardless this is a leak I found.

Fixes #29
