Apply a robustness fix for a caller-side API usage pattern involving the getters and the setters for PLTE, tRNS, and hIST. Passing a pointer returned by the PLTE, tRNS, or hIST getters back into the corresponding setters used to cause the setters to read from a stale pointer. The fix consists in snapshotting the caller's data into a stack-local buffer before freeing the old internal storage. Fixes pnggroup/libpng#836 Reported-by: Iv4n <Iv4n550@noreply.github.com>
