build: Repair and reduce the CMake build dependency graph
A funny thing happened while refactoring the function argument parsing
in the `PNGGenConfig` module: the processing of dependencies inside
the CMake function `generate_copy` got fixed, thanks to an inadvertent
typo correction!
Going down the rabbit hole, we uncovered two issues:
1. A typo in `scripts/cmake/PNGGenConfig.cmake` caused a dependency
declaration to disappear, disrupting the graph. Fortunately, this
disruption was being mitigated by an additional set of (redundant)
symbolic target declarations that kept the CMake build going.
2. The exact string matching inside `scripts/cmake/gensrc.cmake.in`
imposed an artificial limitation, disallowing the use of absolute
file paths.
The typo correction in (1), and the use of regex matching instead of
exact string matching in (2), allowed us to use absolute file paths
in the main CMake file, consistently, thus allowing CMake to recognize
them as uniquely-identifiable nodes in the dependency graph. There
should be no further need to have extra symbolic targets for proper
node identification.
In the end, we shaved off the redundant symbolic target declarations,
retaining only `png_genfiles` and `png_genprebuilt`.

build: Fix apple-non-apple cross building
When cross compiling for an apple platform on a non-apple platform
(or the reverse), `if(APPLE)` in line 32 should refer to the target
platform. Without importing the `APPLE` variable, it refers to the
host platform.

build: Add the CMake build option `PNG_LIBCONF_HEADER`
Running the pnglibconf scripts (script/*.awk) is not always possible.
An AWK interpreter is not always guaranteed to be available; and even
if it is, there are limitations when making cross-platform libpng
builds, especially when the differences between the host platform and
the target platform are significant. For example:
* Building for the Windows (MinGW) target on a Unix development host;
* Building for the iOS target on a macOS development host;
* Building for the Android target on any development host.
In such scenarios, a preconfigured (i.e. prebuilt) pnglibconf.h file,
either taken from the libpng source tree or provided by the user who
wants to make a custom libpng build, becomes a necessity.
In this commit we introduce the build option `PNG_LIBCONF_HEADER` in
order to address this specific use case.
We also specify a version range (3.14...4.0) for the minimum required
CMake program, to future-proof the CMake build for just a little bit
longer.

PNGv3 colourspace precedence rules conformance
This is a major change required by the new PNGv3 colour chunk precedence
rules. It **does not** change the libpng API (png.h) however it changes
the following handling of PNG files:
IFF the PNG file contains colour space information it changes from the
libpng v3 behaviour to the now compulsory PNG v3 behaviour:
1) libpng no longer invalidates colour space chunks because they are
inconsistent.
2) libpng no longer responds to the "png_get_" APIs positively if they
are not present in the PNG but can be deduced from the colour space
chunks that are present.

build: Add scripts/makefile.c89; update other makefiles
Add scripts/makefile.c89 and refactor scripts/makefile.emcc,

Refactor variable definitions inside scripts/makefile.clang,
scripts/makefile.gcc and scripts/makefile.emcc, and start using
the option `-pedantic-errors` unconditionally. This option was
first implemented in GCC version 3.1, and it was available in
Clang and in other Clang-based compilers (e.g. Emscripten) from
the beginning.
Add scripts/makefile.c89, derived from the above makefiles, but
with `-pedantic-errors -std=c89`. We aren't enabling the C89 level
by default, to avoid any incompatibility, whether intentional or
accidental, with the compiler's default language level. However,
we are still continuing to support C89 in the 'libpng16' branch,
and this special makefile can be used for testing purposes.

api(PNGv3): Add support for mDCV and cLLI
This adds APIs to get/set the two remaining new PNG-v3 colour space
chunks. The mDCV API matches that of cHRM. Both chunks support
floating point APIs (all values in the two chunks are real numbers).
Both chunks have a new encoded type, a four-digit-precision fixed-point
number, which cannot be represented in the existing `png_fixed_point`
type, so a `png_uint_32` is used.
Test examples for cICP, cLLI and mDCV are now in pngtest.png, and a
necessary change to the pngunknown.c test program has been made to
accomodate the additions.

build: Move portions from the main CMake file to separate modules
In preparation for the upcoming changes in the build system, any parts
of the CMake file that are unlikely to be affected should be moved out
of the way. This should facilitate an easier resync between the branch
'libpng16' and its successor(s).
Specifically:
* Move the functions `generate_chk`, `generate_out`, `generate_source`
and `generate_copy` to scripts/cmake/PNGGenConfig.cmake.
* Move the function `png_add_test` to scripts/cmake/PNGTest.cmake.
* Leave the function `create_symlink` in place, but add a TODO note.
As we raised the minimum required CMake version to 3.14, we should
now be able to use CMake's built-in function instead.

[libpng16] Add support for reading and writing the cICP chunk
This chunk was added in the third edition of the PNG specification and
contains Coding Independent Code Points (related to color space
description). It is fairly simple as it only contains four fields of one
byte each: Colour Primaries, Transfer Function, Matrix Coefficients,
Video Full Range Flag.
The test file originally comes from the related WPT test case:
https://github.com/web-platform-tests/wpt/blob/master/png/support/cicp-display-p3.png
Note that I reencoded the file to make it match libpng's default
encoding parameters (it only modifies the IDAT chunk).

It is unknown how many user applications have been using these macros.
We have been using `PNG_LIBPNG_VER_DLLNUM` for pngwin.rc, for example.

build: Move scripts/*.cmake.in to scripts/cmake/; add cmake/AUTHORS.md
From the libpng licensing point of view, the build projects, the build
scripts, the test scripts, the CI verification scripts, et cetera, have
not traditionally been part of libpng proper, although some of these,
including the CMake-based build, have been released under the libpng
license.
Considering how the CMake build grew as a result of many contributions
from many contributing authors over a long time, one may argue that it
almost became an individual piece of software in its own right.
Moving on, everything CMake-related shall be placed in the subdirectory
scripts/cmake/ (except, of course, the main CMakeLists.txt). Moreover,
contributing authors shall be acknowledged in scripts/cmake/AUTHORS.md.
Please see scripts/cmake/README.md for more information.

Do not build unused Adler32 code
This removes the default build of an undocumented feature to disable
Adler32 checksums on those systems where it was the default.
The PR is motived by github #187 however it fixes a much more general
problem (#187 is limited to an issue where libpng "crashes" on some
manufacturer systems). The fix is based on a suggestion by @sgowdev who
is the originator of the issue.
When libpng disables the checking of Adler32 checksums it does so by an
undocumented and therefore possibly unsupported call to a zlib function
which does not exist in some versions of zlib.
Fortunately libpng only does this if the caller of libpng explicitly
asks for it to happen. Unfortunately the call to the undocumented
function is still in the compiled and built libpng and this means that
on some systems (as identified in #187) libpng can fail to load or maybe
even crash.
The libpng authors are currently unaware of any program or system that
uses this feature and none has been identified by the contributors to
In this fix an option is added to *enable* the code so that by default
the code is *disabled* - this is a simple generalization of the
suggestion by @sgowdev.
BENEFITS: the problem is eliminated, users of the functionality, if any,
are idenfified, the functionality can be implemented correctly in the
future or it can be removed. Hardly anyone complains.
COSTS: someone will complain that they have to enable an option in a
libpng build to use a feature that never worked consistently in the
first place.
This patch has been tested both with the option enabled and with it
disabled via pngusr.dfa. Tests, checks pass with cmake and configure,
make distcheck passes on configure.

Fix for universal binaries on macOS
Fix the issue of a
clang: error: no such file or directory: 'x86_64'
error on building universal binaries on macOS.
It is also necessary to specify:
-DCMAKE_C_FLAGS="-DPNG_ARM_NEON_OPT=0"
Example CMake command:
cmake -S libpng \
-B build_libpng \
-DCMAKE_OSX_ARCHITECTURES="arm64;x86_64" \
-DCMAKE_C_FLAGS="-DPNG_ARM_NEON_OPT=0"

Update, rename and clean up various scripts
Rename contrib/tools/chkfmt to contrib/tools/chkfmt.sh; refactor:
* Increase the max line length for contrib/**/*.[ch] from 96 to 100.
* Set the max line length for ci_*.sh to 100.
* Use `basename $0` instead of the hard-coded script name.
* Update comments.
Remove contrib/tools/reindent. For automated code formatting, including
indentation, we need a robust solution.
Add an empty line after the hashbang line in all scripts.
Remove the "last changed" version info from comment headers.

scripts: Remove the support for "install" targets from all makefiles
In most of the legacy makefiles (with only a few notable exceptions
such as makefile.linux), the "install" targets have been broken since
libpng-1.5.0beta01. Specifically, the "install-shared" targets produced
incorrect library names, due to a missing symbol in the definition of
the LIBSOREL macro.
Rather than correcting this long-standing and long-untested error, we
decided to remove the support for "make install" altogether, from all
legacy makefiles. Further use of "make install", "make install-static"
or "make install-shared" will fail with an error message.
Going forward, the only tested and supported manners to install libpng
shall be the conventional build and install procedures driven by the
configure script or by the CMake file.

scripts: Set the compiler warning options to "-Wall -Wextra -Wundef"
Considering that "-Wextra" is a more descriptive alternative to "-W",
and that "-Wundef" is a highly useful warning option that has been
available in ancient versions of gcc (version 2.x), we replace all
occurrences of "-W -Wall" with "-Wall -Wextra -Wundef".
Also clean up the makefiles.

cmake: Fix the build on Unix with source files checked out on Windows
The issue is that, by default, Git for Windows checks out text files
with CRLF line endings. This is a problem for awk, which is expecting
Unix-style LF line endings. When cloning on Windows and attempting to
compile on WSL, Mingw or Cygwin, there may be an error from awk.
The fix is to leverage CMake's ability to configure a file and perform
EOL conversions. We copy the awk scripts from the source directory to
the build directory. This portable method ensures they have LF endings,
and the build logic is updated to use the build directory version.
Intentionally avoiding .gitattributes to avoid setting precedent.

Speed up ci_cmake.sh: add "-DPNG_TESTS=OFF" to the list of CMake
variables if CI_NO_TEST is true.
Remove "sudo: false" from .travis.yml.
Refactor .appveyor.yml.

Update configuration for Travis CI; add configuration for AppVeyor CI
Exclude the branch "libpng16" from testing. It's identical to "master".
Also exclude the other (non-current) "libpng[0-1][0-7]" branches.
Parallelize the builds and the unit tests.
For Travis CI, update the build matrix as follows:
* On Linux, use both clang and gcc.
* On macOS, use clang only, with and without Xcode.
For AppVeyor CI, add a build matrix as follows:
* On Windows, use Microsoft Visual Studio 2019 on x86, x64 and arm64.
* Also on Windows, use MSYS2 on x86 and x64.
Use the new scripts/ci_*.sh; remove the old scripts/travis.sh.

scripts: Add general-purpose utilities for continuous integration
Currently, libpng supports three different types of build automation:
the GNU autotools, CMake, and a legacy of hand-made makefiles.
In order to simplify the continous integration of all of the above
build options, we introduce the following scripts:
* ci_autotools.sh: CI utility for the Autotools build
* ci_cmake.sh: CI utility for the CMake build
* ci_legacy.sh: CI utility for the legacy makefiles
