AI95-0303 removes the rule that protected objects with handlers must be
declared at the library level. The AI is a binding interpretation, and thus
applies to earlier versions of the language as well. The new rule is tested
in ACATS test BXC3002.

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

	* sem_ch3.adb (Analyze_Object_Declaration): According to
	AI95-0303, protected objects with interrupt handlers can be
	declared in nested scopes. This is a binding interpretation,
	and thus applies to all versions of the compiler.
