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.

Work on issue #70859548: Reduce amount of time spent collecting pss data
This slightly reduces the frequency we collect pss data, adjusting
some timings and adding back separate timings for when the device
is asleep. (Though note that the "same asleep" timings are currently
the same as "same awake," because those are already pretty infrequent.)
Also add some statistics to procstats to keep track of how many
pss samples have been taken, generally why, and how long they took

Move heavy-weight process state down to cached range.
This allows us to generally treat heavy-weight processes in
the background as cached processes, applying all of the limitations
we want for such things -- disable wake locks, etc.

Add major version code to platform.
It turns the version code into almost a 64-bit integer, with the
new major part being the upper 32 bits.
The only tricky part about this is the backup manager, since it
stored 32-bit version codes in its backup data sets. This is dealt
with by, when the major version code is not 0, writing MIN_INT as
the version code and following that by the full long version code,
which we can detect when reading. Note that this makes backup sets
containing apps with major version codes incompatible with older
versions of the platform.

Add data from /proc/pagetypeinfo to procstats.
This data tells us the number of pages of each type that
are available by page size. It is collected each time
the procstats snapshot is taken, and printed in the
checkin and verbose (dumpsys procstats -a) modes.

Fix issue #28400000: Settings memory UI still showing z-ram...
...but probably shouldn't.
Keep track of whether zram is being included in per-process pss and,
if so, don't add it on separately.

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.
