	* String.cs: Remove unused (and unneeded) internal call defs.
	Reduce duplication (and fix test) for Concat (object,object).
	Avoid allocating zero-length strings in the cases where the
	FX does not do so.

	* UnicodeEncodingTest.cs: Add test cases with an odd number of
	bytes being used in GetString (it does not crash but it does not
	work like MS FX either).
