808ea281a4 [libpng17] Corrected Android builds and corrected libpng.vers with symbol 
prefixing. This adds an API to set optimization options externally,
providing an alternative and general solution for the non-portable
run-time tests used by the ARM Neon code.  It also makes those tests
compile and link on Android.  The order of settings vs options in
pnglibconf.h is reversed to allow settings to depend on options and
options can now set (or override) the defaults for settings.

ec89aefb44 [libpng17] Changed user chunk callback API to respect global and per chunk 
defaults.  Previously a return of 0 from a user chunk callback would result in
the chunk being saved (if this was safe, even if the chunk was unsafe-to-copy);
this change respects the defaults set by the application, so unknown chunks
can be discarded by default and known-safe ones preserved.

6152dbd424 [libpng17] Fixed bug introduced in libpng-1.6.0beta28 that causes libpng to 
handle chunks even when they have been tagged PNG_HANDLE_CHUNK_NEVER.
Also fixed two typos (SUPPOPRTED should be SUPPORTED) in pngrutil.c

2799f74489 [libpng17] Fixed ALIGNED_MEMORY support and 
Allow run-time ARM NEON checking to be disabled. A new configure option:
--enable-arm-neon=always will stop the run-time checks. New checks
within arm/arm_init.c will cause the code not to be compiled unless
__ARM_NEON__ is set. This should make it fail safe (if someone asks
for it on then the build will fail if it can't be done.)

e9760e5e95 [libpng17] Enclosed the new png_get_palette_max API

b96b2b7e90 [libpng17] Fixed missing dependency in --prefix builds. The intermediate 
internal 'prefix.h' file can only be generated correctly after pnglibconf.h,
however the dependency was not in Makefile.am.  The symptoms are
unpredictable depending on the order make chooses to build pngprefix.h and
pnglibconf.h, often the error goes unnoticed because there is a system
pnglibconf.h to use instead.

9bb705e0a8 [libpng17] Fixed make distcheck to skip over the test result files. They were 
being included because the whole of the 'tests' directory is included,
fixed to just include the actual test files and tests/pngstest.  Also
reverted the previous erroneous change to remove the ${srcdir} from the
front of contrib, scripts, projects and added an explanation of what is
going on to Makefile.am

b10867cdc2 [libpng17] Enable parallel tests and rearrange TESTS order to take advantage of 
the massive speed improvements use a make capable of parallel builds
on a multi-CPU machine and pass the right arguments to make (-j10000
for GNU make) to get the build to run in parallel.

f15a5006c8 [libpng17] Removed cc -E workround, corrected png_get_palette_max API. Tested 
on SUN OS cc 5.9, which demonstrates the tokenization problem previously
avoided by using /lib/cpp.  Since all .dfn output is now protected
in double quotes unless it is to be macro substituted the fix should work
everywhere.

9124f3e29a [libpng17] Make symbol prefixing work with the ARM neon optimizations. Also 
allow pngpriv.h to be included for preprocessor definitions only, so
it can be used in non-C/C++ files.
