Also be more careful about canceling fallback keys during focus
transitions, when the application handles the key, or when the
policy decides to do something different.
Fixed a crash due to JNI CallObjectMethod returning an undefined
value (not null) when an exception is thrown.
Fixed a crash due to the policy trying to create a Dialog for
recent apps on the dispatcher thread. It should happen on the
policy's Looper instead.

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.

eglMakeCurrent() would only deref the previous surfaces if the old and
new contexts were the same. eglTerminate() should not touch TLS.
eglReleaseThread() needs to unbind the current context.

If a file was originally considered a video file (because it had
a .mp4 extension, for example), but was then discovered to have
only an audio track, it would update the type, but not the URI
for insertion into the media provider.

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/BinaryHprofWriter.java
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.
vm/Ddm.c
vm/Exception.c
