Subject: [Ada] Dependency between System.Finalization_Root and Ada.Streams

This patch modifies System.Finalization_Root to avoid a dependency on streams.
Type Root_Controlled is now abstract tagged null record.

Tested on x86_64-pc-linux-gnu, committed on trunk

2012-04-26  Hristian Kirtchev  <kirtchev@adacore.com>

	* s-finroo.ads: Remove with clause for
	Ada.Streams. Type Root_Controlled is now abstract tagged null
	record. Remove internal package Stream_Attributes. Root_Controlled
	doesn't need stream attribute redeclaration and avoids the
	dependency on streams.
