Reduce pss collection amount, improve logging.
Tuned rates that we collect PSS, to reduce how much we do
that heavy operation. Added a new way to determine
whether a process has changed to a state for the
"first" time -- now this is when it has gone to that
state for the first time since it was in a lower state.
This will reduce the amount of time we consider a
process to be first to only when it has previously
gone into a higher state than it had before.
Keep track of more fine-grained information about why we
collect a PSS sample (not just internal, but for a single
process, all processes because of a mem state change, all
processes because of a poll).
Started collecting RSS in various places, so we can start
looking at that w.r.t. PSS and see about transitioning to
it is a new primary metric.
Added logging for many of the places where the system
writes its configuration files, so we can more easily
see any bad behavior going on in those areas.
Added some currently disabled code to read smaps directly
instead of using fgets(). Probably won't help, but want
tot test.

Fix PSS/USS Average in procstats
It was broken in I4bf6ac8d, meaning it was broken for the whole NYC.

Refactor ProcessStats.
- Pull most of the inner classes out into their own files.
- Move everything to a new android.app.procstats package.
- Move all of the code that was manipulating the big list
of longs to use the new SparseMappingTable class rather
than doing everything by hand. The logic is unchanged.
- Add a sequence number check to SparseMappingTable so
when the big list of longs and the individual tables are
reset, which happens somewhat independently, we can
assert when one of them doesn't get reset.
