libpng: Update to version 1.2.57

These all fix a potential "NULL dereference" bug that has existed in libpng
since version 0.71 of June 26, 1995.  To be vulnerable, an application
has to load a text chunk into the png structure, then delete all text, then
add another text chunk to the same png structure, which seems to be
an unlikely sequence, but it has happened.
