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.

[lbipng15] Fixed the recently reported 1's complement security issue by
...
replacing the value that is illegal in the PNG spec, in both signed and
unsigned values, with 0. Illegal unsigned values (anything greater than or
equal to 0x80000000) can still pass through, but since these are not illegal
in ANSI-C (unlike 0x80000000 in the signed case) the checking that
occurs later can catch them (John Bowler).
Safely convert num_bytes to a png_byte in png_set_sig_bytes() (Robert
Seacord).

[libpng15] Removed WRITE_WEIGHTED_FILTERED code, to save a few kbytes of the

compiled library size. It never worked properly and as far as we can
tell, no one uses it. The png_set_filter_heuristics() and
png_set_filter_heuristics_fixed() APIs are retained but deprecated
and do nothing.
