scripts: Disable the hardware-optimized compilation in legacy makefiles
Fix the legacy makefile builds on ARM, MIPS and PowerPC, where
hardware-optimized compilation was enabled by default in the generic
source files, but without including the machine-specific source files.

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.

Fix handling incorrect hIST chunks of uneven size
The hIST chunks, used for storing image histograms, contain arrays of
16-bit unsigned integers, and the chunk size is expected to be an even
number. Raise a png_chunk_benign_error() if a hIST chunk fails to meet
this expectation.

Simplify the definition of png_isaligned and avoid compiler warnings
The following pointer subtraction was unnecessary:
((const char*)(ptr)-(const char*)0)
In order to avoid further warnings about casting a wide pointer type
to a narrower integer type, we cast the pointer to the target integer
type through (size_t).
Also fix a comment and reformat the surrounding code.

For the plain ARM platforms where ARM Neon checking is not yet
implemented, issue a slightly more descriptive #error, including

This is similar to d532334ef (Avoid -Wundef warnings when building

In order to appease the compiler warnings that might affect the uses

type to (const void*), and then to (void*), and then to the destination
pointer type. An intermediate cast through an integer type, such as

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.

Adds a top-level target for each generated file and ensures that

custom targets.
Per CMake documentation:
> Do not list the output in more than one independent target
> that may build in parallel or the two instances of the rule
> may conflict (instead use add_custom_target to drive the command
> and make the other targets depend on that one).

ci: Fix the Visual Studio verification on AppVeyor CI
The Unix paths in Bash do not mix well with the Windows paths in CMake.
The uppercase and the lowercase environment variables do not mix well
in MSBuild. Et cetera.
On AppVeyor CI, verification of Windows builds with the Visual Studio
toolchain used to work, perhaps due to one or more lucky coincidences,
but it stopped working after an upgrade on the AppVeyor CI site.
Update ci_cmake.sh as follows:
* Use POSIX commands like "mkdir" and "rm" instead of CMake commands
like "make_directory" and "remove_directory".
* Avoid using absolute paths in the CMake command line; use relative
paths that are accessible from both Bash and Windows.
* Clean up incidental mixtures of Windows and Bash-on-Windows
environment variables like {$TEMP,$Temp,$temp} and {$TMP,$Tmp,$tmp}.

Fix memory leak if eXIf has incorrect crc
Problem description:
Imagine a bitstream with an eXIf data segment that has invalid CRC.
If png_crc_finish() fails at line 2090, info_ptr->eXIf_buf is not freed
(despite the free_me setting at line 2062) because png_free_data() is
not called. png_read_info() is actually looping several time over the
png_eXIf chunk, calling png_handle_eXIf() several time in a row without
freeing the buffer.
This patch fixes the problem by leaving info_ptr's content in a clean
state in case of failure, as it is done at line 2084.

libpng_read_fuzzer to the upstream fuzzer to prevent clusterfuzz
running into OOM.

Avoid random test failures by running pngtest sequentially only
It is unreliable to run pngtest in parallel, due to competing writes
to the same intermediate/output file ("pngout.png").
Customization of this output file name should be possible, but it is
currently broken.

pngminus: Use the system zlib by default
If a zlib source tree exists besides the libpng source tree in the
same parent directory, the pngminus build may fail, unless the zlib
tree is built fully. In order to avoid this failing scenario, do not
use the custom-built zlib by default.
(The custom-built zlib is still necessary on platforms that lack a
system-built zlib.)

arm: Partially revert "Fix a memory leak in the riffled palette [...]"
The memory leak remains fixed, but the associated refactoring is
being reverted. Moving the initialization of the riffled palette
from png_do_read_transformations to png_init_palette_transformations
has caused a regression in some of the test programs.
Although png_init_palette_transformations is the proper place to
perform this initialization, and the test programs are technically
incorrect to fail, we are still undoing that refactoring for the
time being.

Fix a memory leak in pngtest.c
Ensure that row_buf is deallocated not only after a read error, but
also after a write error.
Use the format "%p" instead of "0x%08lx" for printf-ing row_buf in

Fix a memory leak in the riffled palette optimization on ARM; refactor
Move deallocation of riffled_palette from png_write_destroy to
png_read_destroy. The reader (not the writer) is the owner of
riffled_palette.
Move allocation and initialization of riffled_palette from
png_do_read_transformations to png_init_palette_transformations.
Allow riffled_palette inside png_struct only if the ARM Neon
optimizations are enabled.
Rename png_riffle_palette_rgba to png_riffle_palette_rgba8, etc.,
to better indicate the strict applicability of these routines.
Fix an unused parameter warning in the build configurations where
riffled palette optimization is not enabled.
Fix indentation.

Introduce the PNG Reference Library License version 2
The new libpng license comprises the terms and conditions from the zlib
license, and the disclaimer from the Boost license.
The legacy libpng license, used until libpng-1.6.35, is appended to the
new license, following the precedent established in the Python Software
Foundation License version 2.
From now on, the list of contributing authors shall be maintained in a
separate AUTHORS file.
The lists of previous contributing authors, mentioned in the legacy
libpng license and considered to be an integral part of that license,
are kept intact, with no further updates.
