Don't use EGL_SWAP_BUFFER_PRESERVED on surfaces that will
never benefit. Also clean up some confusing naming

On modern versions of Android running in AOT mode
FloatMath is slower than Math. Calls to Math.sqrt(),
etc. are replaced by intrinsics which can be as small
as a single CPU opcode.
When running in interpreted mode the new
implementation is unfortunately slower, but I'm
judging this acceptable and likely to be improved
over time. This change saves a small amount of native
code.
Example timings:
Mako AOSP AOT:
Method: Original / New / Direct call to Math
ceil: 596ns / 146.ns / 111ns
sqrt: 694ns / 56ns / 25ns
Mako AOSP interpreted:
Method: Original / New / Direct call to Math
ceil: 1900ns / 2307ns / 1485ns
sqrt: 1998ns / 2603ns / 1788ns
Other calls Mako AOT:
Method: Original / New
cos: 635ns / 270ns
exp: 566ns / 324ns
floor: 604ns / 150ns
hypot: 631ns / 232ns
pow: 936ns / 643ns
sin: 641ns / 299ns
The advice to use Math directly, in preference to
FloatMath, is still good. FloatMath will be deprecated
separately.

We now use Mapped to not double-count cached pages that are
mapped in to app processes. Also read in some more values that
count towards kernel RAM use, and count buffers as free rather
than used RAM.
It also looks like the zram accounting is broken -- it was never
collecting the total zram reserved space. I need to figure out
how I was finding that before.

Recently we added a way for SkImageDecoder::decode to distinguish
between successfully decoding the entire image and only partially
decoding the image (see https://codereview.chromium.org/647023006).
Only consider a call to decode() a success if the image was completely
decoded. This matches pre-L behavior, and lets the caller know that
they need to try to decode again.
Requires a change to external/skia (I33e6940e247b74b20361ae041f8d36eb600df49f)

If there is a copy, JNI_ABORT does NOT copy back into the
corresponding java array. Changing this to 0 is what you want since
this will copy the data back if needed and free the temporary
storage.

DeferredLayerUpdater had fallen behind RT updates. Re-snap to
latest expectations, ensuring to call requireGlContext() prior
to detachSurfaceTexture to avoid leaking SurfaceTextures

The attribute name resource IDs were never fixed up with
the runtime package ID so we weren't finding attributes
whenever the runtime package ID was different than the build
time one, which happened to be when a shared lib referenced itself
(0x00 vs 0x02).

Drop down the limit on when we log, since under normal operation we
will never get more than a few K of data due to strict mode.
Try to clean up the code paths coming in and out of binder IPCs to
plug any places where we could disrupt the gather flag of a thread,
causing it to keep gathering stack crawls (which is the thing that
is causing our strict mode data to become so large).
