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.

d960ced6e1 Fix pnglibconf.c compilation on OS X including the sysroot path 
Without these flags pnglibconf.c compilation fails because it
includes zlib.h -> zconf.h -> sys/types.h which is not found until we
give a correct SDK path with -isysroot flag.

7cf9a34ade Fix CMAKE_C_FLAGS with multiple values when genout is compiled on MSVC 
Without this patch, CMAKE_C_FLAGS will be processed as a
string/filename on MSVC (e.g. when CMAKE_C_FLAGS is equal
to " /D_WIN32 /D_WINDOWS /W3") and the whole compilation fails.

5ef8d1bfbf Add support to use multiple directories in ZLIBINCDIR variable 
For example, ZLIB_INCLUDE_DIR might include the directory where zlib.h
is located (source dir) and the zconf.h file is located (binary dir).

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.
