AImageDecoder: Make create enforce int32_t dimensions
Bug: 135133301
Test: AImageDecoderTest
AImageDecoderHeaderInfo_getWidth/Height return an int32_t. Ensure at
creation time that the actual image dimensions will fit in int32_t.
In today's code, this should almost never happen:
- PNGs have their dimensions limited to 1000000
- see PNG_USER_WIDTH_MAX and PNG_USER_HEIGHT_MAX in pnglibconf.h
- JPEGs are limited to 65500
- see JPEG_MAX_DIMENSION in jmorecfg.h
- WebPs' dimensions are encoded in 14 bits
- GIFs' dimensions are encoded in 16 bits
- SkBmpCodec and SkWbmpCodec require dimensions to fit in 16 bits
- SkIcoCodec uses SkBmpCodec or SkPngCodec, so their limits are
enforced
- libheif limits to a size smaller than int32_t
It might be possible for a DNG image to be larger, and some of the above
are configurable. Just in case, make AImageDecoder_create fail on such a
large image.
