39df0ced18 [libpng16] Don't install pngcp; it conflicts with pngcp in the pngtools package. 
Moved it from bin_PROGRAMS to check_PROGRAMS in Makefile.am so it will be
built but not installed.

92a7c79db2 [libpng16] Reject oversized iCCP profile length 
The code now validates the ICC profile length against the user chunk limit
before the buffer is allocated, as opposed to doing it while the buffer is read.

This removes the potential to consume virtual address space with a carefully
crafted ICC profile; only an issue on 32-bit systems where a valid profile can
be up to 2^32-4 bytes in length.  libpng never writes beyond the application
supplied limit, but previously it did allocate a buffer of the size specified in
the profile header.  The exploitability of this is almost zero; the address
space is released as soon as the PNG read completes.

Also clean up PNG_DEBUG compile of pngtest.c.

19fefd3a4b [libpng16] Return NULL from png_malloc_array() with a warning instead of calling 
png_error() on failure.  Reject oversized iCCP profile immediately.

cfc19ff1b6 pngcp bug fixes 
The fixed size buffer for the file name being processed could have a byte
written beyond the end; a bug where the test was updated without changing the
size of the buffer.  This commit reduces the buffer to the system maximum.

png_getrowbytes could, in theory, return 0; probably only if there is a bug in
libpng but the code now checks.
