Libpng was written as a companion to the PNG specification, as a
way to reduce the amount of time and effort it takes to support
the PNG file format in application programs. Most users will not
have to modify the library significantly; advanced users may want
to modify it more. The library was coded for both users. All
attempts were made to make it as complete as possible, while
keeping the code easy to understand. Currently, this library
only supports C. Support for other languages is being considered.

===> The following configuration options are available for png-1.6.59_1:
APNG=on: Enable Animated PNG support
SIMD=on: Use CPU-specific optimizations
===> Use 'make config' to modify these settings
graphics/png: security update to 1.6.52
Note this isn't the offered patch from the PR, but one that
instead puts the APNG patch version into a variable.

graphics/png: Fix plist issue with DEBUG enabled
Make sure filenames stay the same when using framework debug flag

graphics/png: exclude SIMD from armv{6,7} in QEMU_EMULATING
The current version added an assert for ARM NEON detection, which
is not supported under QEMU_EMULATING, so the build fails. Prevent
exposing the SIMD option in this case.

graphics/png: fix build with clang 15
Building png with clang 15 results in an error:
contrib/libtests/pngvalid.c:11662:4: error: call to undeclared function
'feenableexcept'; ISO C99 and later do not support implicit function
declarations [-Wimplicit-function-declaration]
feenableexcept(FE_DIVBYZERO | FE_INVALID | FE_OVERFLOW);
^
This is because clang 15 introduced this new warning, and fenv.h only
declares feenableexcept() when compiling for C standards before C11.
The least disruptive way to solve this is to make the port build with
USE_CSTD=gnu89.

graphics/png: add SIMD option
It's enabled by default on aarch64, amd64 and powerpc64le, which should have
optimizations that are enabled in their baselines (NEON, SSE2 and VSX
respectively).

Switch build system from cmake to GNU configure
There are 2 benefits:
- Reduced number of build dependencies (0 now)
- This fixes build on arm64, as configure/Makefile are more updated than
CMakeLists.txt (CMakeLists.txt doesn't know about the arm/arm_init.c
and arm/filter_neon_intrinsics.c files)

- Update graphics/png to 1.6.16
- Patch oolite to build with this new version
