Port FxCop rule CA2004: RemoveCallsToGCKeepAlive

[ghost]

Title: Remove calls to GC.KeepAlive

Description:

If you convert to SafeHandle usage, remove all calls to GC.KeepAlive (object). In this case, classes should not have to call GC.KeepAlive. This assumes they do not have a finalizer but rely on SafeHandle to finalize the OS handle for them.

Dependency: None

Notes:
