For GD, libxpm is an optional dependency, and we should treat it as
such, i.e. if the library is not found, we build ext/gd without XPM
support.
This should also be done for other optional dependencies (like libjpeg),
but since we're close to PHP 8.4.0RC1, we postpone that. However, wrt
libxpm[1] we're taking action immediately, so that we can ship builds
without XPM support, or at least custom builds without XPM support are
possible without modifying the sources.

When PHP gd extension uses the external system GD library, the
HAVE_LIBGD preprocessor macro gets defined in Autotools. On Windows it
was previously always defined when bundled library is used. This fixes
the usage and adds help texts.
This syncs the installed sapi and extension headers on *nix and Windows
systems by installing only what is intended outside of php-src.
- ext/gd: without gd_arginfo.h and gd_compat.h
- ext/hash: php_hash_joaat.h and php_hash_fnv.h added also on Windows
installation; xxhash/xxhash.h added on both installations as it is
included in php_hash_xxhash.h; Include path for xxhash.h changed to
relative so the php_hash_xxhash.h can be included outside of php-src;
Redundant include flags removed
- ext/iconv: without iconv_arginfo.h
- ext/mysqli: mysqli_mysqlnd.h was missing on Windows
- ext/phar: php_phar.h was missing on Windows
- ext/sodium: php_libsodium.h was missing on *nix
- ext/xml: without xml_arginfo.h
- sapi/cli: cli.h was missing on Windows

For parity with non Windows systems, we should `AC_DEFINE` these macros
so that they are defined in config.w32.h instead of directly passed to
the compiler. This allows extensions which have ext/gd as dependency
to check for these macros. E.g. ext/ps does this[1], and fails to
build on Windows, because `HAVE_GD_BUNDLED` isn't defined.

Closes GH-7680.
This backports avif support from upstream libgd into bundled libgd
and exposes the functionality through new imagecreatefromavif()
and imageavif() functions.

Some extension may need to retrieve the `gdImagePtr` from an `GdImage`
object; thus, we export the respective function. To not being forced
to include gd.h in php_gd.h, we use the opaque `struct gdImageStruct *`
as return type.
We also rename php_gd2.dll to php_gd.dll, since there's not really much
point in giving the DLL a version number, since there is no php_gd.dll
for years (if there ever has been). Renaming, on the other hand,
matches the name on other systems (gd.so), and allows to actually use
`ADD_EXTENSION_DEP()`.
While `imagesetinterpolation()` is available as of PHP 5.5.0,
there is no according getter function, so users would have to track the
current interpolation method manually.
To remedy this, we introduce `imagegetinterpolation()` as thin wrapper
for `gdImageGetInterpolationMethod()` (which has been introduced with
libgd 2.1.1), and use `im->interpolation_id` as fallback for older
libgd. Since our bundled libgd does not yet have this function, we add
it.
We also simplify the recently introduced bug79068.phpt, where it is
sufficient to check that the interpolation method has not been changed.
We add PHP bindings for libgd's features to read TGA files, which are
available as of libgd 2.1.0.
As PHP's bundled libgd doesn't yet include the respective features of the
external libgd, we add these.
Since TGA has no easily recognizable file signature, we don't add TGA
support for imagecreatefromstring() or getimagesize() and friends.
The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
We add PHP bindings for libgd's features to read and write BMP files, which
are available as of libgd 2.1.0.
As PHP's bundled libgd doesn't yet include the respective features of the
external libgd, we add these.
* integrate gd_arc.c into gd.c (as of gd-2.1.0-alpha1)
* rename gd_color.c to gd_color_match.c (as of gd-2.1.0-alpha1)
* remove mathmake.c (as of GD_2_0_34RC1)
* rename xbm.c to gd_xbm.c (as of gd-2.1.0-alpha1)
ext/gd/libgd/gd_webp.c has been taken from libgd[1]. Mainly, gd_error(X) has
been subsituted by zend_error(E_ERROR, X) and BGD_DECLARE(X) by X. Further
modifications are obvious from the diff.
All GD tests are passing, what raises hope, but we need more WebP tests,
anyway.
