21d9e6e0fb SKIP definition in pngstest.c misplaced 
The SKIP definition needs to come after the png.h include (see all the other .c
files in contrib/libtests) because it depends on PNG_LIBPNG_VER.  This commit
puts it in the correct place.

98af505439 Fix MSVC Level 4 warning 
MSVC does not like (uInt) = -(unsigned) (i.e. as an initializer), but it is fine
with it if the conversion is explicitly invoked by a cast.

801b925edf pngvalid.c: correct progressive read input buffer 
The previous version of the code invariably passed just one byte at a time to
libpng.  The intention was to pass a random number of bytes in the range 0..511
(and this is what happens now).

8f506d3257 SSE filter speed improvements for bpp=3. 
- memcpy-free implementations of load3() / store3().
    These should have less variance compiler to compiler.

    - call load3() only when needed at the end of a scanline.
    In the middle, we can use the faster load4(), ignoring that byte.

9821954ecc contrib/libtests/timepng: make robust, improve 
The code no longer gives up/fails on invalid PNG data, it just skips it (with
error messages).  The code no longer fails on PNG files with data beyond IEND.
Options exist to use png_read_png (reading the whole image, not by row) and, in
that case, to apply any of the supported transforms.  This makes for more
realistic testing; the decoded data actually gets used in a meaningful fashion.

98c6fa2495 PNG_IMAGE_PNG_SIZE_MAX error correction 
The macro underreported the size (by up to 512 bytes) of an 8-bit non-color
palette based memory format because it failed to take into account that the
memory palette has to be expanded to full RGB when it is written to PNG.

This is not likely to be a serious bug because the macro is new, the memory
format in question is likely to be rarely used and the result of an undersized
buffer fails in a safe way.
