Closes GH-7091.
This backports avif support from upstream libgd into bundled libgd
and exposes the functionality through new imagecreatefromavif()
and imageavif() functions.
Closes GH-7026.

1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.

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.
* PHP-7.4:
cleanup gd build with system libgd - drop need to use libpng with system libgd - drop need to use libjpeg with system libgd - drop need to use libXpm with system libgd - drop need to use libfreetype with system libgd - improve configure comments
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.
We expose the image resolution related GD functionality to userland
by introducing `imageresolution()` as getter/setter. Given only the
image argument, it returns the current resolution as indexed array.
Given only a second argument, it sets the horizontal and vertical
resolution to this value. Given three arguments, it sets the horizontal
and vertical resolution to the given arguments, respectively.
gdImageOpenPolygon() has been introduced with líbgd 2.0.29, so we finally
add a PHP binding for it, and port the respective libgd functionality to
PHP's bundled libgd.
Instead of rolling our own in the bundled libgd, we use libgd's anti-aliased
drawing API. This way imageantialias() is also available, when built against
a system libgd.
We add the necessary PHP bindings for both functions which are available
as of GD_2_0_12 (released 2006-04-05). The API of imagegetclip() is modelled
according to imageftbbox().
