Also, allow scan interval for framework and supplicant
to be configured at build time or run time
Bug: 4144882
Change-Id: I877f4bcc872597b44d3f4da85cf2bc0f16e09444
This patch adds a mechanism for capturing, filtering, transforming
and injecting input events at a very low level before the input
dispatcher attempts to deliver them to applications. At this time,
the mechanism is only intended to be used by the accessibility
system to implement built-in system-level accessibility affordances.
The accessibility input filter is currently just a stub.
It logs the input events receives and reinjects them unchanged,
except that it transforms KEYCODE_Q into KEYCODE_Z.
Currently, the accessibility input filter is installed whenever
accessibility is enabled. We'll probably want to change that
so it only enables the input filter when a screen reader is
installed and we want touch exploration.

This updates the various documentation on screen sizes to discuss
the exact screen dimensions that are now associated with each size.
In addition, the screen sizes vs. densities table is updated to
include a number of additional representative screens.

- mostly was visible in Settings apps / Wi-Fi networks summary info for each network
- correctly setup the local SkPaint for advances computation
- improve test app for adding live resizing

Added new drag_can_accept and drag_hovered XML attributes and the View
logic to support them. Drawable states are now refreshed automatically
when a drag starts/ends and when a drag crosses the boundary of a
participating view.

Summary:
frameworks/base
- fix profiling to collect data beyond the first snapshot
- avoid many small files, accumulate data over process lifetime
libcore:
- add support for VM specific sampling, trying to cut down overhead
- added support for converting snapshot files to text format
- fixed race in profiler when stopping
dalvik
- added VMStack.setThreadStackTrace interface for filling a stack
trace into an existing StackTraceElement[]
Details:
frameworks/base
Changed snapshots from text to binary hprof format (bumping version to 3)
Changed from one file per snapshot to one file per process lifetime.
Restart profiling after snapshot.
core/java/com/android/internal/os/SamplingProfilerIntegration.java
Add quick test in maybeSnapshot to avoid doing work when the
SamplingProfilerIntegration is disabled. Make maybeSnapshot
private. Remove unneeded memory allocation in handleLowMemory.
core/java/android/app/ActivityThread.java
libcore
Added ThreadSampler interface. This allows VM specific thread
sampling optimizations. The portable version continues to use
Thread.getStackTrace().

dalvik/src/main/java/dalvik/system/profiler/PortableThreadSampler.java
dalvik/src/main/java/dalvik/system/profiler/SamplingProfiler.java
Add VMStack.setThreadStackTrace and use in new DalvikThreadSampler
to avoid allocating a full stack trace when only a limited depth
is desired.

dalvik/src/main/java/dalvik/system/VMStack.java
Refactored BinaryHprof.readMagic out of BinaryHprofReader so it
can be used by HprofBinaryToAscii converter to probing file
types. Added magic number constant to be shared between readMagic
and BinaryHprofWriter.

dalvik/src/main/java/dalvik/system/profiler/HprofBinaryToAscii.java
Removed unneeded HprofWriter interface. Changed to simpler static
interface to write HprofData to binary and text formats.

dalvik/src/main/java/dalvik/system/profiler/AsciiHprofWriter.java
dalvik/src/main/java/dalvik/system/profiler/BinaryHprofWriter.java
dalvik/src/test/java/dalvik/system/profiler/SamplingProfilerTest.java
Added support for reading snapshot files created by
SamplingProfilerIntegration by stripping the text header to allow
easier conversion to the text format.
dalvik/src/main/java/dalvik/system/profiler/HprofBinaryToAscii.java
Fixed race between Sampler and
SamplingProfiler.stop. SamplingProfiler.stop previously simply
called the Sampler's TimerTask.cancel method, but this does not
wait for a currently running Sampler to finish. The TimerTask
documentation says the only reliable way to do this is to have the
run() cancel itself, so that is what is now done, with new code to
ensure that SamplingProfiler.stop does not return until the
Sampler has been terminated.
dalvik/src/main/java/dalvik/system/profiler/SamplingProfiler.java
dalvik
Refactored VMStack_getThreadStackTrace to create helper getTraceBuf
used to implement new VMStack_setThreadStackTrace. The new version
interface fills an existing StackTraceElement[], avoid allocating
unnecessary StackTraceElements.
vm/native/dalvik_system_VMStack.c
Refactor dvmGetStackTraceRaw to create dvmSetStackTraceRaw which
fills in an existing, potentially smaller, StackTraceElement[].
vm/Exception.c
vm/Exception.h
Change stack depths to be unsigned to avoid signed/unsigned comparison warnings.

A cache control header containing both no-cache and max-age attribute does not
behave as expected.
Cache-Control: no-cache, max-age=200000
Will set expired to 20000ms seconds, ignoring the no-cache header. My
interpretation is that the no-cache header should not be ignored in
this case.
