* Headers/Foundation/Foundation.h: Add NSMetadataQuery.h to

include list.
	* Headers/Foundation/NSMetadataQuery.h: New header for class.
	* Source/GNUmakefile: Add NSMetadataQuery.[hm] to makefile.
	* Source/NSMetadataQuery.m: Abstract implementation for
	NSMetdataQuery.  The idea is much like NSFileStream and other
	classes which have operating system specific implementations.
	On linux this will, most likely, interface with locate/slocate.
	I'm not certain what it will talk to on Win32.

-	* Source/NSAutoreleasePool.m (-emptyPool): Fixed not to push a pool to 
-	the cache in the ARC_RUNTIME implementation, -dealloc does it already. 
-	For the same current pool instance, the ARC_RUNTIME implementation was 
-	calling push_pool_to_cache() twice, once in -emptyPool and another 
-	-dealloc. Which meant a pool still in use could be reused, then it was
