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.

829cba63d3 Fix undefined behavior in pngvalid.c 
Undefined because (png_byte) << shift is undefined if it changes the signed bit
(because png_byte is promoted to int).  The libpng exported functions
png_get_uint_32 and png_get_uint_16 handle this.

Bug reported by David Drysdale as a result of reports from UBSAN in clang 3.8.

This changes pngvalid to use BE random numbers; this used to produce errors but
these should not be fixed as a result of the previous changes.

bd7143e6eb [libpng15] Fixed 'unused' warnings and mergeed with libpng16 pngvalid. 
Various warnings revealed by configurations added to the tested
configurations in libpng 1.6 need corresponding fixes in libpng 1.5.
This takes the libpng 1.6 pngvalid.c and adds it back to libpng 1.5,
however one write-only test is currently disabled because it does not
work; possibly because of failures to reset or initialize the deflate
stream correctly in write-only cases.
