Safeguard against "Collection was modified during iteration" exception when iterating over the passed in IEnumerable of diagnostics.

Fixes #802 

Specially handle root namespace constituents in SourceNamespaceSymbol.IsDefinedInSourceTree.

Safeguard against "Collection was modified during iteration" exception when iterating over the passed in IEnumerable of diagnostics.

Some of the build task names where still set to their old values from
when they were in MSBuild. This changes the names to the proper names
and also ports any missing resources to the resource files in the current
build task assembly.

Fix intermittently failing unit test SuppressDuplicateAnalyzerExceptionDiagnostics.

Since we added support to "add the complete exception stack trace to description field of analyzer exception diagnostics" (see #1742), the test verifying duplicate analyzer exception diagnostics has failed intermittently. Although we don't have a concrete repro, its pretty likely that is due to the fact that the stack trace of the exceptions generated by the analyzer used by this test (http://source.roslyn.io/#Roslyn.Compilers.UnitTests/Diagnostics/SuppressMessageAttributeTests.DiagnosticAnalyzers.cs,272) differs slightly, causing this behavior.

We should deem a pair of analyzer exception diagnostics which have same ID and message, but may have different exception trace, to be equivalent to reduce noise in the error-list output.

reduce size of key string for each analyzer by removing unnecessary portion.

Adjust implementation of SourceNamespaceSymbol.IsDefinedInSourceTree to account for the fact that constituents of a root namespace are implicitly defined in every syntax tree and, therefore, should be visited for the purpose of collecting diagnostics within a syntax tree. Without this, an unexpected “unnecessary imports” diagnostic could be reported for a syntax tree and some expected diagnostics could remain unreported for the tree.

Fixes internal TFS bug 1142095

Commit any existing rename session when a document is saved or when
debugging run mode is entered. This ensures rename sessions are
completed before Edit and Continue sets the buffers to readonly when
debugging begins or when break mode is exited.

Fix NullReferenceException during debugging

When opening a file during a debugging session, VS sets its buffer read-only when it is not editable. To do so, VS asks its document to the workspace but in some cases, the workspace returns nothing, causing NRE and VS Crash. In this PR, we defensively add a null check and log it to make a further investigation easier.

Noth that Issue #1204 is tracking to fix this issue directly (by enforcing the workspace to load projects before EnC).
