Log message:
	PR44411: Make VMSystem.nanoTime independent of wall time where possible.
	
	2010-11-04  Andrew John Hughes  <[email protected]>
	
		Provide a fallback for systems without POSIX timers.
		* native/jni/java-lang/java_lang_VMSystem.c:
		(currentTimeMillis): New function which provides
		the behaviour for both Java_java_lang_VMSystem_currentTimeMillis
		and the fallback by obtaining the result of gettimeofday.
		(Java_java_lang_VMSystem_nanoTime): Return currentTimeMillis
		multiplied by a 1000 if a monotonic clock is unavailable.
		(Java_java_lang_VMSystem_currentTimeMillis): Split main behaviour
		out into currentTimeMillis and then return its result divided by a
		1000.

		PR classpath/44411
		* native/jni/java-lang/java_lang_VMSystem.c:
		(Java_java_lang_VMSystem_nanoTime): Implement
		using POSIX monotonic clock support and clock_gettime.
		(Java_java_lang_VMSystem_currentTimeMillis):
		Use old nanoTime method (which uses gettimeofday) to
		provide the current time in milliseconds.
		* vm/reference/java/lang/VMSystem.java:
		(currentTimeMillis()): Make native with its own implementation
		rather than using nanoTime, which should be
		independent of wall-clock time.
