Two Skia changes required for
https://googleplex-android-review.git.corp.google.com/#/c/357301/:

https://codereview.chromium.org/23464068/:
Use the default resync_to_restart in jpeg.

Our version requires rewinding the stream, which is not always
supported. Instead, depend on jpeg's default version.

This is required because the new framework code assumes that an
image stream will never be rewound unless it's at the beginning.

https://codereview.chromium.org/23717055/:
Add a buffered SkStream class.

This is used by Android to buffer an input stream which may not
otherwise be able to rewind.

Add a test for the new class.

This change allows us to buffer natively, and to only buffer the
beginning of the stream, which is all that is needed by the image
decoders.
