pakutoma b721d0f71e Fix phpGH-10648: add check function pointer into mbfl_encoding 
Previously, mbstring used the same logic for encoding validation as for
encoding conversion.

However, there are cases where we want to use different logic for validation
and conversion. For example, if a string ends up with missing input
required by the encoding, or if a character is input that is invalid
as an encoding but can be converted, the conversion should succeed and
the validation should fail.

To achieve this, a function pointer mb_check_fn has been added to
struct mbfl_encoding to implement the logic used for validation.
Also, added implementation of validation logic for UTF-7, UTF7-IMAP,
ISO-2022-JP and JIS.

(The same change has already been made to PHP 8.2 and 8.3; see
6fc8d014df. This commit is backporting the change to PHP 8.1.)

libmbfl

This is libmbfl, a streamable multibyte character code filter and converter library, written by Shigeru Kanemoto.

The original version of libmbfl is developed and distributed at https://github.com/moriyoshi/libmbfl under the LGPL 2.1 license. See the LICENSE file for licensing information.

The libmbfl library is bundled with PHP as a fork of the original repository and is not in sync with the upstream. As such, the libmbfl directory is directly modified in the php-src repository.
