Summary: replace JVM_GetStackTraceDepth and JVM_GetStackTraceElement,
with JVM_GetStackTraceElements that gets all the elements in the
StackTraceElement[]
These improvements were found during the investigation for replacing
Throwable with the StackWalkAPI. This change also adds iterator for
BacktraceBuilder to make changing format of backtrace easier.
Tested with -testset core, RBT nightly hotspot nightly tests on all
platforms, and jck tests on linux x64. Compatibility request is approved.
