PR44411: Make VMSystem.nanoTime independent of wall time where possible.

2010-11-04  Andrew John Hughes  <ahughes@redhat.com>

	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.
