We simplified the way we track whether or not a dex file is used by
other apps. DexManager in the framework keeps track of the data and we
no longer need file markers on disk.
Test: device boots, foreign dex markers are not created anymore

This matches a corresponding libcore change. It is to allow
libcore to use this value as a default when no other value is
explicitly set, e.g. in the system server or during testing
with vogar.

This new command is used to attach runtime agents to a running application:
attach-agent <PROCESS> <FILE>
Attach an agent to the specified <PROCESS>,
which may be either a process name or a PID.
Test: m test-art-host, manual testing:
. invalid syntax, missing arguments
. invalid syntax, extra arguments
. invalid numeric PID
. invalid process name
. valid process, not debuggable
. valid process, missing agent

Add option '--streaming' to 'am start' and 'am profile' commands.
If the option is given, the output of method trace profiling
will be streamed into the specified file, so the output is no
longer limited by the buffer size.
Test: m -j48 test-art-host;
m -j48 ART_TEST_TRACE=true ART_TEST_TRACE_STREAM=true test-art-host;
I also tested manually. Tried all 8 combinations of
sampling/instrumention
streaming/non-streaming
'am start --start-profiler' / 'am profile start'
The output files are all in expected shape.

SystemProperties.get() is not particularly fast,
especially if a string is returned. Since ro.* values
are unable to be changed, there's no need to
continously re-query them. Cache the value at
static init time to trivially fix this.
Test: refactoring CL.

The EGL Init thread spends a lot of time loading shared libraries,
which involves reading pages and adjusting VM pages. Previously it was
a low priority thread, which meant that when it blocked while holding
a VM lock, it might take a while to be scheduled again once ready, so
it would hold the VM lock longer than necessary, blocking other
threads waiting on soft faults, etc. Classic priority inversion.
Leaving the thread at normal priority causes it to interfere *less*
with critical-path Activity launch work.

Preloading EGL in Zygote was originally a memory footprint
optimization, but it turns out to be an important app startup time
optimization as well. Preloading EGL in Zygote is incompatible with
updatable graphics drivers, but we don't want to do it on-demand as
part of drawing the first frame either, since that increases
first-frame latency unacceptably.
This change removes Zygote preload, and instead loads EGL on a
low-priority background thread immediately after choosing which
graphics driver to use. This means it is usually done well before
drawing the first frame, without significantly disrupting other
activity launch work.
Test: observe systrace of Calculator launch on bullhead

If an Exception thrown by a Binder call implements the Parcelable
interface, then parcel it and rethrow back at the caller. There is
strict requirement that these Parcelable exceptions must be defined
by the system (as determined by checking the ClassLoader). We prefix
the Parcelable contents with a length so that native code can skip
over the blobs.
Define a new ParcelableException class that can be used to transport
exceptions that cannot be modified to add Parcelable behavior, and
switch ExceptionUtils to use this new class for sending IOExceptions.
Test: builds, boots, wrapped exceptions work

The GraphicsEnvironment class is given information during application
start, and makes it available to EGL/GLES/Vulkan loaders that don't
have easy access to the VM or to the application Context. Currently
only the driver path is handled, but the existing support for setting

should move here.

Commit 794c8b0b3f fixed the race condition
when requesting data wipes via uncrypt. We have similar issue with
RecoverySystem.installPackage(). It first requests to set up the BCB,
then triggers a reboot. These two steps should finish atomically.
This CL switches to calling
RecoverySystemService.rebootRecoveryWithCommand(), which guards the two
steps with synchronized blocks.
