freezer: disable on "am dumpheap <pid>"
heapDump() is used to collect process heaps via "am dumpheap <pid>". It is
alternative to "dumpsys meminfo" and would hang if called on a frozen
process. In this patch:
- disable freezer before the binder transaction to collect heap data
- install a man-in-the-middle callback to handle completion of
collection. The new callback will invoke the original one from the client
and then enable the freezer again.
