95e0094f85 Eliminate signed overlow in png_64bit_product 
The previous version produced a signed overflow as a result of both the
& 0xffff on the most significant bits of a negative argument; this
converted (-1) into 65535 which resulted in a subsequent overflow.
Since signed overflow is undefined in C90 the code has been modified to
correctly calculate a signed result.  This requires changing the 'hi'
result parametr to a signed value.

This has been code reviewed solely by the author.  A further code review
is highly desireable.  Nevertheless the code compiles without warnings
from clang and without the prior detection of an overflow.  Since it no
longer truncates any of the intermediate values this should be enough to
ensure that it is correct.

09dcb906a7 Remove unsigned overflow 
The previous code always results in an unsigned arithmetic overflow,
this is well defined but produces errors from clang with the option to
detect unsigned overflow.  As the expression only gets evaluated once
per row in this version of libpng it is easier just to rewrite it.

8d4110bd61 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.
