Change uses of Unchecked_Conversion (which is obsolete since Ada 95) to Ada.Unchecked_Conversion to avoid warnings recently enabled in GNAT. Same for Unchecked_Deallocation. Previous patch only changed files used for production build; this patch changes files used for debug builds (and also for gnatsocks, for completeness). no-precommit-check (to avoid complains about copyright headers) Change-Id: I0a753b06a46ce56778b8de9c96607515bea7cf84

-- 1) DO NOT instantiate this package for a controlled type. If you

-- do, at best finalization will not work correctly. At worst, you

|
|
-- 2) DO NOT instantiate and use Ada.Unchecked_Deallocation for the type
|
|
-- Shared_Access belonging to an instantiation of this package. If
|
|
-- you do, you are likely to end up corrupting the heap, and possibly
|
|
-- crashing the entire process.
