b9c58ab617c257dbece105167b21e94faad67320 03-Dec-2013 Leon Scroggins III <scroggo@google.com> Merge AssetStream with AssetStreamAdaptor.

Add enums to the constructor for AssetStreamAdaptor to choose the
different behaviors used by the (former) two different classes.

The old clients of AssetStream now get the following features of
AssetStreamAdaptor
- Debugging statements on error.
- The stream is an SkStreamRewindable.
- getLength() returns the correct value, and the old way of getting
the length (read(NULL, 0)) is no longer implemented, since it is
no longer used.
- isAtEnd() returns the correct value. ToT Skia makes it pure virtual,
so some implementation is necessary.

ca32021b43f326af7d3f4ae041f8db297f98a518 20-Aug-2013 Leon Scroggins III <scroggo@google.com> Replace stream wrap-function w/ more specific ones

The current stream wrapper returns a potentially incorrect
value for a call to getLength(), is typically copied into
another stream (not always in the same way), and doesn't
always take advantage of its underlying data (like when it
is an Asset). The overall goal of this CL is to provide the
caller with something that is ready to use, depending on
what is asked for. If a copy is desired, the copy is made
before being returned to the caller.

core/jni/android/graphics/Bitmap.cpp:

Include SkStream.h, since it is no longer included by
CreateJavaOutputStreamAdaptor's header file.

core/jni/android/graphics/BitmapFactory.cpp:

Pass an SkStreamRewindable to decoding functions, as Skia
decoders will be updated to only take an SkStreamRewindable
(which makes more sense because they require rewinding).

Call the more specific GetRewindableStream to get a
rewindable stream.

Remove copyAssetToStream which has been moved to Utils.

In nativeDecodeAsset, pass forcePurgeable as allowPurgeable
in doDecode. Technically the old code worked, but it checked
the BitmapOptions again.

Remove getFDSize, which is no longer used.

core/jni/android/graphics/BitmapRegionDecoder.cpp:

Remove redundant buildSkMemoryStream. nativeNewInstanceFromStream
now calls CopyJavaInputStream, which handles the copy.

Copy the Asset directly, using common code, rather than creating
an AssetStreamAdaptor to copy.

core/jni/android/graphics/CreateJavaOutputStreamAdaptor.cpp:
core/jni/android/graphics/CreateJavaOutputStreamAdaptor.h:

Provide new interfaces to access data from a Java InputStream.
The new interfaces are more specific about what type of stream
is desired.

Use forward declarations where possible.

Remove doSize, which gives a misleading answer to the question
of how long the entire stream is.

TODO: Only call FindClass etc once.

core/jni/android/graphics/Movie.cpp:

Check for an asset stream, and use it if possible. Then call
GetRewindableStream if there is not an asset.
Remove the memory leak. Call DeleteLocalRef to delete the
allocated memory.

core/jni/android/graphics/Picture.cpp:

Call the new interface.

core/jni/android/graphics/Utils.cpp:
core/jni/android/graphics/Utils.h:

Make AssetStreamAdaptor inherit from SkStreamRewindable so it
can be passed to Skia decoding functions once they require it.

Add CopyAssetToStream (moved from BitmapFactory.cpp) so it can
be used by multiple files.

graphics/java/android/graphics/BitmapFactory.java:

Remove the call to mark, which is now done natively.

Remove the BufferedInputStream. Mark/reset is now handled
by native code.

Allow decodeStream to handle a FileInputStream by using the
FileDescriptor, if it is seekable. In decodeFileDescriptor,
call nativeDecodeStream instead of decodeStream so this new
functionality will not loop.

Call setDensityFromOptions in decodeFileDescriptor.

graphics/java/android/graphics/BitmapRegionDecoder.java:

Remove the BufferedInputStream. Mark/reset is now handled
by native code.

ddb76c4644756b31be948d70aaa8ee541dd94999 24-Nov-2010 Kenny Root <kroot@google.com> Change assets to use 64-bit API

The asset system and supporting libraries were using off_t instead of
off64_t to access files larger than 2GB (32-bit signed). This change
replaces all off_t with off64_t and lseek64.

There is a new utils/Compat.h added for Mac OS compatibility.

Also fixed some size-related compiler warnings.

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.
