Rework and fix "adb shell dumpsys meminfo"
We now collect more detailed information splitting the maps into
additional useful categories.
Fixed some bugs in account, such as not correctly handling all of
the current dalvik allocations.
The activity manager now prints a final summary of all pss organized
by the apps and the categories.
