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.

pngvalid with 'limit' checks disabled in RC+
...
This widens the 'limit' check on the internally calculated error limits in the
'DIGITIZE' case (the code used prior to 1.7 for rgb_to_gray error checks) and it
changes the check to only operate in non-release builds (base build type not RC
or RELEASE.)

Fix inconsistent handling of invalid zlib data
...
In libpng 1.6 zlib initialization was changed to use the window size in the zlib
stream, not a fixed value. This causes some invalid images, ones where CINFO is
too large, to display 'correctly' if the rest of the data is valid. This
provides a work-round for zlib versions where the error arises (ones that
support the API change to use the window size in the stream).
