Implement php_handle_avif() using libavifinfo

See #80828 and the internals@ mailing list discussion at
https://externals.io/message/116543

Use libavifinfo's AvifInfoGetFeaturesStream() in php_handle_avif() to
get the width, height, bit depth and channel count from an AVIF
payload. Implement stream reading/skipping functions and data struct.
Use libavifinfo's AvifInfoIdentifyStream() in php_is_image_avif().

Update the expected features read from "test1pix.avif" in
getimagesize.phpt.

Closes GH-7711.

`ADD_EXTENSION_DEP()` relies on the `PHP_<extname>` config variables to
be set to `"yes"`, and since the standard and date extension are always
enabled, we define the respective variables uncoditionally.

Move Oniguruma related config stuff to where it belongs

Oniguruma is exclusively used by ext/mbstring, and only if mbregex is
enabled. Therefore it is unnecessary and confusing to have Oniguruma
related config stuff scattered elsewhere.

While we're at it, we also remove the referral to the bundled libonig
which is removed as of PHP 7.4.0, and the duplicated call to
`PHP_INSTALL_HEADERS()`.

Sync leading and final newlines in source code files

This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines.

Sync leading and final newlines in source code files

This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines.

According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.

C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."

Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.

Remove unused Git attributes ident

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.

functionality introduced in RFC `argon2_password_hash` is compatible with
both versions, as the library version that package maintainers package may
differ.

Argon2d is not suitable for password_hashing. To ensure best practices

--with-argon2 implies the full feature set of Argon2, whereas this
feature only implements Argon2i within password_*. Consequently
the feature flag was renamed to --with-password-argon2
