Add data from /proc/pagetypeinfo to procstats.
Change-Id: I3c455fe69244927dc5aebdf5ddb7b0badf6aeee8
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.

Add support for ICU data pinning in the Zygote
Change-Id: If693e8cbb737186fdf0a3169d024bef08c8ceb6a
We handled stale wakelocks (wakelocks that disappear from /d/wakeup_sources)
differently in previous version of Android. They would be set stale, but still be
updated with their previous counts (they would never disappear).
The method setStale has been replaced with endSample(), which is semantically different.
Once a SamplingTimer has endSample() called, it expects any future calls to update() to
be a new sample, meaning the entire amount passed to update() is included in the kernel
wakelock's total. Since stale wakelocks were never removed from the list, this would
increase by large amounts when nothing had actually changed.
This was exacerbated by the fact that there was a bug where the last wakelock in
/d/wakeup_sources was never parsed, so if the order ever changed, this "stale" wakelock
would suddenly re-appear and the entire amount reported would be charged to the wakelock,
instead of just the difference since the last update.
All this was exposed when we added support to handle wakelocks that would disappear and
reappear with smaller values, meaning the kernel had pruned them from its accounting and
reset them.

Instead of in activity thread. That way, we can warm up (ie,
precompute cached values) this provider and AndroidBCWorkaroundProvider
(which are installed together) so that the computation doesn't
happen in the app. As a result, the time spent in the first call to
SSLSocketFactory.getDefault() decreases by ~5ms in angler userdebug.
Measured with an app calling SSLSocketFactory.getDefault in onCreate
and timed it with System.currentTimeMillis() .

Upstream ICU caches use SoftReferences. On Android this means
that useful cached data initialized in the Zygote are "lost" when
the Zygote GCs and cannot be shared with apps. This change makes use
of an Android patch to ICU to ensure References created during
Zygote initialization are "strong". i.e. they are never collected.
This prevents them being GCd and ensures they can be shared between
applications.
After switching ICU to use strong references, this change
also creates DecimalFormatSymbols objects for common ULocales
(ROOT, US and the user's default, if different). DecimalFormatSymbols
makes use of an ICU Reference cache and this alone has been shown to
improve the construction time of java.text.DecimalFormat by 1-1.5
milliseconds on a Seed device. This saving applies the first time one
is created in each app for each locale, and again if SoftReferences
have been cleared.
The cost to the heap size of the Zygote has been measured at ~107k.
This value will change as more caches are switched to use the new
CacheValue class.
Formatting is typically performed on the UI thread and the intention
of this change is to reduce app start up time and jank in apps like
the Dialer which do a lot of formatting when scrolling lists. The
change may also enable more virtual memory page-sharing between
apps, though this is not the specific goal.

This makes the time spent in the first call of an app to
SSLSocketFactory.getDefault() drop from ~240 ms to ~50 ms. In M
it was around ~6ms. This is due to the fact that, while instantiating
the default factory, all providers are initialized.
In order to obtain the timings above, I created an app calling
SSLSocketFactory.getDefault in onCreate and timed it
with System.currentTimeMillis() .

Ensure app op restrictions reset when the app that set them dies.
Change-Id: Iebbe27690aeac898807c13ef05c730697dbb406a
We were not keeping track when an app that set an app op restriction
dies to clean up after that. As a result we may end up with stale
restrictions that will be there until the device reoots - not cool.
This change adds remote binder death tracking and simplifies the
code as adding the formed would have made more complex.

This is a follow-up to my previous CL [1] for Bug 15922840 so that we
can clear the following variables in a more reliable way.
- PhoneWindowManager#mLastInputMethodWindow
- PhoneWindowManager#mLastInputMethodTargetWindow
The idea behind CL [2] is that when InputMethodManagerService (IMMS) is
switching from an IME to another IME, IMMS can send a signal to
WindowManagerService (WMS) to remember the current IME's inset so that
the system can continue using it to reduce jank until the new inset is
specified by the next IME. As summarized in Bug 28781358, however, if
the next IME does not show the window after the IME switch, WMS (or
PhoneWindowManager to be precise) keeps using the previous IME's inset
unexpectedly until the new IME shows its window. All we have seen in
Bug 15922840 and Bug 26663589 fall into this category.
The idea of this CL is just adding a hidden API to InputMethodManager so
that InputMethodService#clearInsetOfPreviousIme() can surely terminate
the IME transition state managed in PhoneWindowManager, rather than
relying on a hack of calling SoftInputWindow#show() and
SoftInputWindow#hide(), which actually does not work for Bug 26663589.

Note that addressing all the corner cases in [2] still requires lots of
non-trivial change. Hence this CL focuses only on Bug 26663589 (and
the case we handled in Bug 15922840).

If we're going to show metadata about a resolved implicit intent that
is targeted to a single package with multiple potential targets,
populate the ResolveInfo with the label and icon of the target
package's ApplicationInfo and set resolvePackageName. This helps use
cases such as EXTRA_INITIAL_INTENTS in ChooserActivity, where
sometimes apps set target packages but not components.
