When the malloc code is instrumented, the global _brksize variable should not be transferred. However, when the malloc code is not instrumented, failing to transfer _brksize would reset the heap upon state transfer. In this patch, the magic pass stores the flag indicating whether memory function instrumentation is disabled, in the target process. This allows libmagic to check this flag during state transfer, to see whether it should transfer _brksize or not. Change-Id: Ia004651e21e08b0ed3f5305865c53c6659e18f38
