   avcodec/pngdec: bound decompressed zTXt/iCCP size (decompression-bomb guard)
   decode_zbuf() inflates zTXt (compressed text) and iCCP (ICC profile) chunk
   payloads into an AVBPrint created with AV_BPRINT_SIZE_UNLIMITED and never
   checks the decompressed size. A ~100 KB zTXt chunk of compressed zeros
   expands to 100 MB; larger ratios or multiple chunks can exhaust memory.
   
   Abort with AVERROR_INVALIDDATA once the decompressed output crosses a hard
   cap (16 MiB).
   
   Verified with a crafted PNG (1 KB compressed -> 100 MB decompressed): without
   the patch the chunk fully decompresses, taking >100 MB; with the patch the
   inflate loop aborts and the decoder logs "Compressed PNG chunk expands
   beyond 16777216 bytes" / "Broken zTXt chunk" while the rest of the image
   decodes normally.
   
   Reported by Franciszek Kalinowski (isec.pl / striga.ai) and Bartosz Smigielski.
