A new counter MemHeapUsage was added to OSD_MemInfo class to examine program heap size
DRAW command meminfo got new option -h (--heap ) to use new counter data
The following testcases were changed to use new option -h of DRAW command meminfo
myCounters[MemHeapUsage] now will always be refilled every time the OSD_MemInfo::Update() function is called.
Fixed testcases to use meminfo -h instead of meminfo -w to detect memory leaks more properly.
