504ebd427d Back out READ/WRITE_INTERLACING changes 
Now that the code works consistently so that these just switch off the support
for having libpng do the interlace/deinterlace the old names make more sense,
restoring them avoids cruft in the configuration file and avoids an unnecessary
version specific change.

3184947a25 chunk handling and transform rewrite 
This implements a new chunk parse implementation that can be shared, it
is currently shared by the progressive reader and the sequential one
(not, yet, the writer).

The patch also implements shared transform handling that is used
throughout.

7974d60f54 [libpng17] Merge with libpng-1.6.14beta07 
Removed "option READ_COMPRESSED_TEXT enables READ_TEXT" from pnglibconf.dfa,
  to make it possible to configure a libpng that supports iCCP but not TEXT.
Removed "option WRITE_COMPRESSED_TEXT enables WRITE_TEXT" from pnglibconf.dfa
Only mark text chunks as written after successfully writing them.

72389dec42 [libpng17] Cleaned up and enhanced the configure option; libpng now correctly 
links and tests against zlib with a prefix; tests have been clarified; and
irrelevant or obsolete things (as defined by the autotools man page) have
been removed.

cad0150d12 [libpng16] Corrected handling of row_pointers in example.c and added some 
comments.  It has apparently been wrong since libpng-1.0.1c (confusing
use of a 1D and a 2D array for the image source).

f2715a558a [libpng16] Revised example.c to put text strings in a temporary character array 
instead of directly assigning string constants to png_textp members.
This avoids compiler warnings when -Wwrite-strings is enabled.

fcd301daed [libpng16] Changed png_memcpy to C assignment where appropriate. Changed all 
those uses of png_memcpy that were doing a simple assignment to assignments
(all those cases where the thing being copied is a non-array C L-value.)
Added some error checking to png_set_*() routines and removed the
reference to the non-exported function png_memcpy() from example.c. Fixed
the Visual C 64-bit build - it requires jmp_buf to be aligned, but it had
become misaligned.

5d56786eff [libpng16] Implemented 'restrict' for png_info and png_struct. 
Added new "png_structrp" typedef. Because of the
way libpng works both png_info and png_struct are always accessed via a
single pointer.  This means adding C99 'restrict' to the pointer gives
the compiler some opportunity to optimize the code.  This change allows that.
