[libpng17] Do not read invalid sBIT chunks. Previously libpng only checked sBIT
...
values on write, so a malicious PNG writer could therefore cause
the read code to return an invalid sBIT chunk, which might lead to
application errors or crashes. Such chunks are now skipped (with
chunk_benign_error).

[libpng17] Completed full working pngimage test program and added two test
...
scripts. Fixed combination of ~alpha with shift. On read invert alpha,
processing occurred after shift processing, which causes the final values to be
outside the range that should be produced by the shift. Reversing the
order on read makes the two transforms work together correctly and mirrors
the order used on write.

[libpng17] Make png_read_png() and png_write_png() prototypes in png.h depend
...
upon PNG_READ_SUPPORTED and PNG_WRITE_SUPPORTED.
Removed dependence on !PNG_READ_EXPAND_SUPPORTED for calling
png_set_packing() in png_read_png().

[libpng17] Added pngimage test program for png_read_png and png_write_png.
...
This is a work-in-progress; no tests are run automatically at present and
the program by virtue of exhaustively testing all the transforms is
very slow.

[libpng17] Allow unversioned links created on install to be disabled in

configure. In configure builds 'make install' changes/adds links like png.h
and libpng.a to point to the newly installed, versioned, files (e.g.
libpng17/png.h and libpng17.a). Three new configure options and some
rearrangement of Makefile.am allow creation of these links to be disabled.

[libpng17] Handle zero-length PLTE chunk or NULL palette with png_error()
...
instead of png_chunk_report(), which by default issues a warning
rather than an error, leading to later reading from a NULL pointer
(png_ptr->palette) in png_do_expand_palette().

[libpng17] Made transform implementation functions static. This makes the
...
internal functions called by png_do_{read|write}_transformations static.
On an x86-64 DLL build (Gentoo Linux) this reduces the size of the text
segment of the DLL by 1208 bytes, about 0.6%. It also simplifies
maintenance by removing the declarations from pngpriv.h and allowing
easier changes to the internal interfaces.

[libpng17] Bookkeeping: Moved functions around (no changes). Moved transform
...
function definitions before the place where they are called so that
they can be masde static. Move the intrapixel functions and the
grayscale palette builder out of the png?tran.c files. The latter
isn't a transform function and is no longer used internally, and the
former MNG specific functions are better placed in pngread/pngwrite.c
