We now write battery history directly into a buffer, instead of
creating objects. This allows for more efficient storage; later
it can be even better because we can only write deltas.
The old code is still there temporarily for validation.

In addition to the primary change in the subject, also some minor cleanup of javadoc, typos, CloseGuard warning, etc found while working on a new AbstractAccountAuthenticator.

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

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/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.

Also..
- Added a class java doc for CorrectionSpan
- Removed FLAG_DEFAULT
- Changed the return type of getSuggestions from Array<CharSequence> to String[]

Fix action menu item layout focusability so that only the full item is
focusable. Fix up listeners appropriately.

The input dispatcher sends a HOVER_ENTER to a window before dispatching
it any HOVER_MOVE events. For compatibility reasons, the window will
*also* receive the HOVER_MOVE. When the pointer moves into a different
window or the pointer goes down or when events are canceled for some reason,
the input dispatcher sends a HOVER_EXIT to the previously hovered window.
The view hierarchy behavior is similar. All views under the pointer
receive onHoverEvent with HOVER_ENTER followed by any number of HOVER_MOVE
events. When the pointer leaves a view, the view receives HOVER_EXIT.
Similarly, if a parent view decides to capture hover by returning true
from onHoverEvent, the hovered descendants will receive HOVER_EXIT.
The default behavior of onHoverEvent is to update the view's hovered
state by calling setHovered(true/false). Views can query their current
hovered state using isHovered().
For testing purposes, the hovered state is mapped to the pressed
drawable state. This will change in a subsequent commit with the
introduction of a new hovered drawable state.

Hide the action bar upon finishing a mode if it was hidden when the
mode started. If show() is called while the mode is active, the bar
will not hide when the mode finishes.

- CorrectionSpan is a span which has suggestions made by IME.
This has a function to change the current IME to other IME specified
in this span. For security reasons, only the current IME
is allowed to use this function through InputConnection.
(IME token is used for checking the validity of it.).
- CorrectionSpan stores following information:
flags, subtype Id, InputMethodInfo Id, suggests, locale, original string

This is used when there is only one application available and the user has
not chosen to start it by default.
If more than one application is available we continue to use UsbResolverActivity
