The first patch fixes a FATE issue.

The second patch was discussed on IRC. I got a LGTM from Kasper, but sending to ML here and applying in a few days if there's no objections.

A few things discussed:
1) There's no need to expose the gamma table as another function as it's only used here.
2) This patch includes the patch on the ML sent as "avcodec/pngdec: warn when reading tv-range cICP chunks" which got a LGTM from Lynne on IRC. If this is applied that one has no need to be applied.

Leo Izen (2):
  avcodec/pngenc.c: avoid writing cICP when inappropriate
  avcodec/pngdec: read colorspace info when decoding with AVDISCARD_ALL
