previously applied to libpng-1.6.28rc03 but withdrawn to allow time for QA.

13a354f81e Remove 'defined' within macro 
This removes the use of a macro containing the pre-processor 'defined'
operator.  It is unclear whether this is valid; a macro which
"generates" 'defined' is not permitted, but the use of the work
"generates" within the C90 standard seems to imply more than simple
substitution of an expression itself containing a well-formed defined
operation.

319c9852bf Unsigned overflow 
Remove all currently detected cases of unsigned overflow.  Detection is
runtime, so test case dependent.  The changes to pngvalid.c eliminate
spurious and probably invalid tests with one while loop exception.

Apart from that and the change to the dependence on the intended
unsigned overflow in pngtrans.c the changes are limited to altering the
meme for an unsigned 'x' from:

   while (x-- > 0)

to

   for (; x > 0; --x)

This works because, in all cases, the control variable is not used in
the loop.  The 'while' meme was, at one time, warn'ed by GCC so it is
probably a good change, for some weird religious value of good.

f0b453bc3e [libpng16] pngfix zero-length IDAT fix 
When an input file contains a zero length IDAT and pngfix is not applying the
IDAT rechunking (--max) option pngfix will go into a loop writing the zero
length IDAT for ever.

This is a fairly minor issue for interactive use; zero length IDAT is very rare,
the problem is obvious (pngfix hangs) and the fix (use --max, or --max=4096
etc), while not obvious, is easy.

For non-interactive use, e.g. trying to automatically repair a PNG that cannot
be read by libpng, there are security consequences:

1) pngfix hangs.  This may permit a DoS attack.
2) When the --out option is used pngfix will just keep writing.  This is a very
likely DoS scenario.
