frameworks/base: vectorize Bitmap operations

Enable gcc vectorizing optimizations for Bitmap operations within
libandroid_runtime.so.  Adds -ftree-vectorize -mvectorize-with-neon-quad
-fprefetch-loop-arrays to functions and compiles Bitmap.cpp in ARM mode
(necessary to enable vectorizing optimizations) for appropriate targets.

Framwork: Add support for variable size pattern lockscreen (Part 1/2)

Part 2: http://review.cyanogenmod.org/#/c/28534/2

Forward port of: http://review.cyanogenmod.org/#/c/20613/

The default size has been replaced with a constant PATTERN_SIZE_DEFAULT=3
It now parses the longInt as a byte, no longer requiring a get/set Int function.
Negative numbers and sizes over 127 do not make sense, so a byte works well.
In addition the logging has been removed.

Patch Set 1-2: Initial port

Patch Set 3-5: New implementation using seperate file for non standard sizes

Patch Set 6: Use AOSP code style

Patch Set 7-9: Remove static code

Patch Set 10: Correct a comment

KeyChain: return null instead of throw

The API documentation says it will return null if the key isn't found.
We get null back from the keystore daemon when it can't retrieve the
data, so just return null back to the API caller.

Applying ChannelScrolling to remove calculateDragAngle

To avoid angle calculation changed the logic to use virtual areas.
When try to drag or pan, check where the current touch point locates
and determine how to drag a page.

Allow three digit phone numbers

The comment for the PHONE pattern says:

"<digit><digit|sdd>+<digit>"

But the actual pattern requires that the string contains
more than that. A phone number should be allowed to be
three digits.

StreamingZipInflater: fix mmap'd end of read

When reaching the end of a mmap'd segment, it was erroneously trying to
read more data. This is because we were reading data one character at a
time, so we never reached the Z_STREAM_END result without going through
the loop once more.

Fix ListView is not scrolled properly with arrows

According to ListView's layoutChildren logic, it detaches all children
and rebuilds its children based on visible area which might omit
invisible elements in the adapter.

In this case, arrowScroll methods only tries to find next scroll
candidates from its children so user is unable to scroll more with
D-pad.

This fixes the issue by look forward next child among the adapter as
well as children.

Check and fail early if requested wallpaper size exceeds maximum texture size.

This fixes an issue where OpenGL initialization succeeds but buffer allocation fails because the requested wallpaper size
is too large (or otherwise unsupported) by the graphics hardware. This fixes an issue where SystemUI crashes constantly
on the PandaBoard when connected to a full HD display. Tested only on PandaBoard, no access to alternative hardware.

Track stack memory in MemoryInfo.

In /proc/pid/maps the main stack is identified as "[stack]". In Linux 3.4
thread stacks are identified as "[stack:<tid>]" where <tid> is the thread ID of
the thread using that stack. Add support in MemInfo's otherStats to track
memory being used by the stack.

Add sanity check on the length of the otherStats array.
Add detail messages to two null pointer exceptions.

Audio continue to played even if paused manually

Currently, audio will resume playing after a phone call
or notification even if the user had manually paused playback.

This patch addresses that by introducing a new player state
to distinguish the user pausing playback and the browser
losing audio focus for some other reason. Audio will only
 resume if the browser temporarily lost audio focus and
not when the user has manually paused playback.
