Update RenameTracking state after isRenamableIdentifierTask

Commit rename on more editing cmds and refactorings

C# Syntax unit test passing on Mono

Dont Case Correct Identifier to Symbols that the identifier cannot bind

Fixes internal bug #762964

Rename tracking usually triggers the TrackingSessionUpdated event
whenever the buffer changes, except for buffer changes that occur before
the _isRenamableIdentifierTask completes. Prior to this change, rename
tracking would get stuck in its initial state between the completion of
_isRenamableIdentifierTask and the next buffer change. We now also
update the session when _isRenamableIdentifierTask completes.

PropertySymbolKey considers indexer metadata name

Use an unmanaged stream during PDB writing

Fixes internal bugs 991517 and 1142701

Commit rename on the following commands:

- Cut/Paste, if the operation occurs outside a rename span
- MoveSelectedLines
- Command-based refactorings (Change Signature, Extract Interface, and
Encapsulate Field)

This updates our cibuild.sh script to include self hosting the VBC
build in addition to the CSC build.

The support is limited to our Mac runs only for the moment due to Linux
not being upgrade to the proper mono runtime.   This will be updated in
the near future.

Remove CodePage1252Encoding and try to use the built-in Encoding. If not available, then fallback to Latin1

Cross Platform build issues

Fixes #50

Fixes internal bug #916341

Update PropertySymbolKey.Resolve to consider the metadata name of
indexers. Prior to this change, resolving regular properties considered
the metadata name but resolving indexers did not. Checking the metadata
name for indexers is important for distinguishing between explicit
interface implementations.

More improvements to the ?. codegen.

Include pseudo-variables in CompileGetLocals

Invoke SetAdditionalFiles on compiler inputs when initializing from msbu...

Invoke SetAdditionalFiles on compiler inputs when initializing from msbuild csc task fails and we fall back to initializing from model. This should fix the local unit test failures in MSBuildWorkspace additional file unit tests that some developers are hitting.

Even though there is no semantical difference between box/callvirt and constrained/callvirt here, we do not want to cause unnecessary boxing.

Compiler was handling this case correctly for structs, but missed the case of generic type parameters.
(old compiler did use constrained with generic type parameters as well)

Fixes #2111

Better handling of unary operators (like:  - foo?.Bar  )
Better lowering strategy for nullable receiver - we no longer rewrite to a ternary ?: in such cases which leads to more optimization opportunities.
