Backport changes related to BitmapRegionDecoder from HoneyComb to
Gingerbread.

Bug: 3309014

////////////////////////////////////////////////////
This is a combination of 7 commits.
Revert "Do not merge."

This reverts commit f7681f84918c27f6a626681ce37ed2a236c44e82.

Change-Id: I46fd710600b1649773eaea2d9abc2b21a592f9a6

Fix a initialization bug in BitmapRegionDecoder.

Change-Id: I6c1151fd34970a84d4de52d664d9a5dc464892c5

Fix segfault when tring to throw IOException.

Change-Id: I530cc4409ba4ca17cec933afad077c5f60ba554f

Fix 3122139, where previewing an attachment for the second time will
fail.

Use AutoFDSeek to mark and restore the position before we read data from
the descriptor.

Change-Id: I3d4f012dce486e19b113bc90a98b94031cfa8195

Add inPreferQualityOverSpeed into BitmapFactory.Options.

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.

6b849e2123be98eb2a1a25b8abf0b13a279ce952 07-Sep-2010 Wei-Ta Chen <weita@google.com> Unhide BitmapRegionDecoder.

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.

can not be rewinded isShareable should be set to false.

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.

2a2c5cd74128a7750f05683614c9824c9262addc 03-Jun-2009 Wei-Ta Chen <weita@google.com> Modify the decoding logic in the FD case when a purgeable flag is set,
and lower the threshold of bitmap size for using ashmem().

For the decoding logic, we now go through the "non-purgeable" path if isShareable is false,
irrespective of the value of the purgeable flag.

c70e06bbfac0d92ec218a32e35d9d7fa80f23cc9 24-Apr-2009 Mike Reed <reed@google.com> Add (hidden for now) purgeable bitmaps

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.
