[libpng16] fix: Write order of colourspace chunks should conform to PNG v3
...
cICP was written after PLTE, not before. The other chunks were output
in an order which does not match the new PNG-v3 "priority" order.
This change outputs all chunks in the "priority" order; highest
precedence first. This means that the PNGs so written conform to
PNG v3 (cICP), and allow a streaming app to handle chunks in order,
without buffering data which may later be overridden.
Note that PNG-v3 establishes the idea of dropping ancillary chunks
which are inconveniently ordered in the definition of how APNG chunks
are handled.
This is a cherry-pick of commit 945f2602a0ea05a7938b2f52df9ef16cf3440291
from branch 'libpng18'.

[libpng16] Corrected fix for unknown handling in pngtest. This reinstates the
...
libpng handling of unknown chunks other than vpAg and sTER (including
unsafe-to-copy chunks which were dropped before) and eliminates the
repositioning of vpAg and sTER in pngtest.png by changing pngtest.png
(so the chunks are where libpng would put them).
