Propagating lossless conversion from libgd to our bundled gd.
Changing "quantization" to "quality" as in libgd.
Adding test.
IMG_WEBP_LOSSLESS is only defined, if lossless WebP encoding is
supported by the libgd used.
Closes GH-7348.
Some AVIF image generators didn't include the PixelInformationProperty
(pixi), even though strictly speaking they should. In v0.9.2, libavif
began requiring this. Let's disable it so we can read those images too.
We also remove xfail from test on FreeBSD.
Closes GH-7253.
Thanks to Joe Drago for help with the AVIF detection code.

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.

This PR replaces the bundled libgd includes from #include <foo.h> with
#include "foo.h" for gd-related headers to avoid including headers that
may be available in system directories instead of the expected local
headers.
Closes GH-6975.
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.

The color resolution is expected in bits 4-6 of the packed fields byte
of the logical screen descriptor (byte 10 of the GIF data stream),
according to the specification[1], section 18.

As seen in the gdImageRotateBicubicFixed() function the same setup
occurs but it uses signed integers, therefore we use also use
signed integers in gdImageRotateBilinear()
Moreover, these two functions have been removed upstream in
https://github.com/libgd/libgd/commit/bd6d2e101f6f1df106d1cd2e2dc8058a5538109b
therefore we should also mimic upstream and remove them...
Thanks to @cmb69 for pointing it out.
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.
This has been reported to upstream[1], but since ext/gd never calls
`gdTransformAffineCopy()` for a palette image, it is not a bug for PHP.
Therefore we apply the fix to master only.
