The new field allows a developer to use a more accurate by
slightly slower IDCT method in JPEG decode. This in turns improves the
quality of the reconstructed image.
The field by default is not set and thus does not affect existing
applications.

1. Rename LargeBitmap to BitmapRegionDecoder
2. Move the instantiations of BitmapRegionDecoder out of BitmapFactory.
3. Remove the use of MemoryFile in BitmapRegionDecoder, since MemoryFile's API had been modified in master. Otherwise, the change will break the master build.
4. Move AssetStreamAdaptor, AutoFDSeek and nullObjectReturn to Utils.h because BitmapFactory.cpp and BitmapRegionDecoder.cpp both need to use these utility functions.
Most of the modifications, except for (2) and (3), were reviewed in https://android-git.corp.google.com/g/#change,64716 .
However, that change broke the master build due to (3) and was reverted eventually.
So, instead of withdrawing this change and waiting for that change to be checked in again, I merge the two changes into one.

Before this change, all framework assets would be decoded at drawing time
outside of zygote. This was forcing all apps to re-decode the assets and
zygote to keep an in-memory copy of each asset. This behavior is now
opt-in by setting the inPurgeable flag on BitmapFactory.Options.

- Do better about figuring out when to stop them and other related window
management.
- Fix problem where we were not redrawing the surface when the orientation
changed. This was the cause of the device hang.
Merge commit '11ea33471e1a14a8594f0b2cd012d86340dd3bd8'

Allow for screen density drawables in compatibility mode.
This change allows us to use drawables that match the current screen
density even when being loaded in compatibility mode. In this case,
the bitmap is loaded in the screen density, and the bitmap and
nine-patch drawables take care of accounting for the density difference.
This should be safe for existing applications, for the most part, since
they shouldn't really be pulling the bitmap out of the drawable. For
the small rare chance of them breaking, it worth getting the correct
graphics. Also this will only happen when there is actually a resource
of the matching density, and no existing apps should have resources for
anything besides the default density (though of course all of the
framework resources will be available in the native density).
As part of this, the bitmap density API has been changed to a single
integer provider the DPI unit density.
BitmapFactory::Options now let you specify if the resulting bitmap can be
"purgeable". If so, then its decoded pixels may be purged when not actively
being drawn, freeing up that RAM. When such a bitmap is drawn, it will
automatically be re-decoded on demand. This is done by having the bitmap
keep a reference/copy of the encoded data.
Where it is a reference or a copy is controlled by the "shareable" flag in
Options. If this is true, the implementation *may* just reference the encode
data (e.g. a file descriptor) rathern than making a complete copy of it.
Currently, purgeable is not supported for generic inputstreams, but is
enabled for byte-array, file-descriptor, and assets, though for impl
reasons only file-descripts are currently enabled for "shareable", but that
may change in the future.
