d332c67da7 [libpng16] Start-up code size improvements, error handler flexibility. 
These changes alter how the tricky allocation of the initial png_struct and
png_info structures are handled. png_info is now handled in pretty much the
same way as everything else, except that the allocations handle NULL return
silently.  png_struct is changed in a similar way on allocation and on
deallocation a 'safety' error handler is put in place (which should never
be required).  The error handler itself is changed to permit mismatches
in the application and libpng error buffer size; however, this means a
silent change to the API to return the jmp_buf if the size doesn't match
the size from the libpng compilation; libpng now allocates the memory and
this may fail.  Overall these changes result in slight code size
reductions; however, this is a reduction in code that is always executed
so is particularly valuable.  Overall on a 64-bit system the libpng DLL
decreases in code size by 1733 bytes.  pngerror.o increases in size by
about 465 bytes because of the new functionality.

681c1fc02a [libpng16] Correct configure builds where build and source directories are 
separate.  The include path of 'config.h' was erroneously made relative in
pngvalid.c in libpng 1.5.7.

efaeadaa86 [libpng16] Added pngconfig.h file. This indirect reference to config.h avoids 
problems with build scripts that search for config.h and find an
inappropriate one in the standard paths.

eb26ee6602 [libpng16] Fixed race conditions in parallel make builds. With higher degrees 
of parallelism during 'make' the use of the same temporary file names such
as 'dfn*' can result in a race where a temporary file from one arm of the
build is deleted or overwritten in another arm.  This changes the
temporary files for suffix rules to always use $* and ensures that the
non-suffix rules use unique file names.
