Support >= php8.0

[jooola]

We currently only support php7.2 -> php7.4. To install LibreTime on recent distributions using the php distribution packages, we will have to support >=php8.0.

A work around would be to install php7.4 from the php sury repository.

Most of our dependencies support php8.0, but we are using some abandoned dependencies that needs upgrading as well or replacements:

• https://github.com/jooola/celery-php needs to be tested against php8.0
• https://github.com/propelorm/Propel https://github.com/jooola/propel1 we have been tracking work from https://github.com/tworzenieweb/Propel. An interesting branch we could use https://github.com/tworzenieweb/Propel/tree/feature/php8.0

Test dependencies:

• phpunit/dbunit I wonder if we should drop or fork this.
• phpunit/phpunit zf1s seem to be maintain a phpunit version for testing their work https://github.com/zf1s/phpunit with php8.0

Probably some other dependencies (indirect) that also needs some upgrading.

Feel free to pick this issue and help us support php8.0 ! Help is greatly appreciated !

I don't know if we want to only support >= php8.0 once this is implemented. As it would probably make our life easier. Though support for 7.4 and 8.x should be doable, but as php7.2 and 7.3 will be dropped with #2035 and #2036

Some progress was made that we start trying to use:

• zf1s/zf1@d7ba9c8
• https://github.com/tworzenieweb/Propel/tree/feature/php8.0

Considering 7.4 became EOL on January 1st, yes, only php8 should be supported moving forward. :)

Dropping 7.4 support requires dropping support for the distros that ship it, so it is more of a discussion that just drop it because upstream dropped it. Distro maintainers still provide support even if upstream doesn't
