Verified that nobody should be using these APIs, and they've been
deprecated long enough that we can remove them.

Hides getFd & getFileDescriptor due to lifecycle concenrs.
Adds ASharedMemory_dupFromJava to allow sharing a shared
memory region between Java & Native as safe as possible.
Mis-use results in an FD leak instead of double-close.

Previously, wakeup alarms (for an app) were using the battery-on
timebase. Now they will instead use the battery-on-screen-off timebase.
In this way, apps won't be penalized for wakeups that occurred when
the device was being actively used anyway.
Also bumps up report version to 25.
Also bumps up parcel version.

Fixes: 64149996
Test: manually verified count doesn't increase when screen-on
Change from the previous attempt:
- Fixed the helper class. The original version had a few bugs.
- Bundle.readFromParcel() now handles a Parcel with a read-write helper
properly.
** Comparison **
The following charts are the actual measurement with and without the fix,
using "dumpsys system".
- The red bar is "total private dirty".
- The X axsis is time since boot.
Without fix:
- #1 First boot:
-- https://docs.google.com/spreadsheets/d/1CbmU8cQQQw7n7tyqbZi3beRHNuzqcmJgdvzDpi40Q1I/edit#gid=1971317391
-- Private dirty stabilizes at ~16.8M.
-- Loading system packages took 1.8 seconds.
- #2 Second boot:
-- https://docs.google.com/spreadsheets/d/1CbmU8cQQQw7n7tyqbZi3beRHNuzqcmJgdvzDpi40Q1I/edit#gid=982210726
-- Private dirty stabilizes at ~17.5M.
-- Loading system packages took 0.5 seconds.
With fix:
- #3 First boot:
-- https://docs.google.com/spreadsheets/d/1R6lL0AnAp93HnrqWujJFNgOjj6wvGicgDlbDAevbc3g/edit#gid=791764875
-- Private dirty stabilizes at around the same level as #1.
-- Loading system packages took 1.9 seconds.
- #4 Second boot:
-- https://docs.google.com/spreadsheets/d/1CbmU8cQQQw7n7tyqbZi3beRHNuzqcmJgdvzDpi40Q1I/edit#gid=1820894299
-- Private dirty stabilizes at around the same level as #1.
-- Loading system packages took 0.7 seconds.
Package manager start up time with and without the fix:
- (Ignored ones that are too fast; probably the thermal throttling didn't kick in.)
- https://docs.google.com/spreadsheets/d/1CbmU8cQQQw7n7tyqbZi3beRHNuzqcmJgdvzDpi40Q1I/edit#gid=499396796
- Before: 3.5 seconds (average of 5 reboots)
- After: 3.6 seconds (average of 5 reboots)
Package scan speed comparison:
- With the fix, first boot.
08-03 08:49:56.851 1000 779 779 I PackageManager: Finished scanning system apps. Time: 2133 ms, packageCount: 143 , timePerPackage: 14 , cached: 0
08-03 08:49:56.971 1000 779 779 I PackageManager: Finished scanning non-system apps. Time: 121 ms, packageCount: 11 , timePerPackage: 11 , cached: 0
- With the fix, second boot.
08-03 08:53:29.387 1000 779 779 I PackageManager: Finished scanning system apps. Time: 484 ms, packageCount: 143 , timePerPackage: 3 , cached: 143
08-03 08:53:29.424 1000 779 779 I PackageManager: Finished scanning non-system apps. Time: 37 ms, packageCount: 11 , timePerPackage: 3 , cached: 11
** Conclusion **
- This CL wil slightly slow down the boot time (0.2 seconds on a thermal-throttled bullhead), but
the system server's ram consumption will go down to the no-cache level.
- Using the package cache is still faster than not using it.

(cherry picked from commit 8529150860)
HAL impls will depend hwbinder.jar instead of framework.jar on
build-time, but on runtime framework.jar will be used.
This is to cut the circular dependency when using configstore from
Android framework. Also added JNI call to HwBinder.java to cut
configstore's dependency on systemproperty in framework.jar.
Note that hwbinder.jar is LOCAL_UNINSTALLABLE_MODULE and so it won't be
installed in an actual image.
