48052cc9cb Bug 1526717. Guard against libpng calling the info callback more than once. r=aosmond 
libpng uses the first IDAT chunk it encounters as a signal that it has read all header chunks and to send the info callback.

The testcase png has an IDAT chunk, then a z chunk (not a known chunk type), and then another IDAT chunk.

libpng tracks if we are in an "after idat" state, and throws a benign error if it encounters another IDAT chunk in "after idat" mode, but it just continues normally, processing the idat chunk as if it were the first and therefore sends the info callback again. This seems silly.

28978c4f66 Bug 523950 - Part 2. Expose image decoder type and SourceBuffer to owners. r=tnikkel 
Later in the patch series, we use the new APIs to facilitate cloning of
an existing decoder. This is useful when you want to redecode the same
image with the exact same configuration but from the very beginning.

0e7000fdce Bug 1352282. Always fill in the number of loops when decoding an APNG file. r=aosmond 
If we were doing a first frame only decode we wouldn't fill in this value. The spec says this chunk must come before any image data so it should always be available at the end of any full decode (whether it be truly full or first frame only).

7d4bd52fae Bug 1330907 - Rename Telemetry::ID to Telemetry::HistogramID. r=dexter 
Changed |print("enum ID : uint32_t {", file=output)| to |print("enum HistogramID : uint32_t {", file=output)| at line 53 of the file |toolkit/components/telemetry/gen-histogram-enum.py|, and then replaced all the textual occurrences of |Telemetry::ID| to |Telemetry::HistogramID| and |ID| to |HistogramID| in 43 other files.

a1c7482bc4 Bug 1131446. mFrameHasNoAlpha is mostly pointless. r=seth 
Starting with bug 391583 we detect whether a png image has any transparency
during decode. I don't think this is worth doing anymore. We choose the format
of image based on the png header, that should be sufficient for the performance
improvement we desire from opaque images. This gets us faster image decoding.
