Update libpng, libogg, libvorbis to newest versions

This also fixes a sneaky divide by zero in glpng, because some PNG's width was read incorrectly by the old libpng. (I wonder why it worked anyway...)

/* Maximum size of the dynamic table. The maximum number of code structures is
1444, which is the sum of 852 for literal/length codes and 592 for distance
codes. These values were found by exhaustive searches using the program
examples/enough.c found in the zlib distribtution. The arguments to that
program are the number of symbols, the initial root table size, and the
maximum bit length of a code. "enough 286 9 15" for literal/length codes
returns returns 852, and "enough 30 6 15" for distance codes returns 592.
The initial root table size (9 or 6) is found in the fifth argument of the
inflate_table() calls in inflate.c and infback.c. If the root table size is
changed, then these maximum sizes would be need to be recalculated and
updated. */
