Make Bitmap_createFromParcel check the color count. DO NOT MERGE

When reading from the parcel, if the number of colors is invalid, early
exit.

Add two more checks: setInfo must return true, and Parcel::readInplace
must return non-NULL. The former ensures that the previously read values
(width, height, etc) were valid, and the latter checks that the Parcel
had enough data even if the number of colors was reasonable.

Also use an auto-deleter to handle deletion of the SkBitmap.
