Add php8 as CI target

[ChristophWurst]

We might have to also adjust the distro as precise is a bit outdated but let's see

Once I know the tests indeed fail I'll tackle #74

FYI Travis is kind of shutting down. I suggest moving to Github Actions. If you need help please let me know ✌️

I hopefully migrated to travis-ci.com, lets see how it goes.

don't get your hopes up. they limit the "open source credit" that you get. and while the docs say you can get credit for open source, they actually shut that program down. so either you pay or you have to use something else. it's affecting us a lot at Nextcloud and they did that without any warning. just as a heads-up.

Ok, so this runs but it doesn't pass. but I see other builds did just fail as much: https://travis-ci.org/github/tchwork/utf8/builds/752168267. @nicolas-grekas do you have any idea for how to support such a wide range of php versions with phpunit?

Some new failures include

1) Patchwork\Tests\PHP\Shim\IntlTest::testGrapheme_substr

Failed asserting that '' is identical to false.

2) Patchwork\Tests\PHP\Shim\IntlTest::testGrapheme_strpos

Failed asserting that 0 is identical to false.

/home/travis/build/tchwork/utf8/tests/PHP/Shim/IntlTest.php:122

3) Patchwork\Tests\PHP\Shim\MbstringTest::testmb_stubs

Honest question: are you really using this package? Why not https://github.com/symfony/polyfill-mbstring/ and the likes instead?

[ChristophWurst]

Well this is embarrassing for me. I checked in detail and while we still depend on this package, another package recently also added the intl-normalizer polyfill from Symfony into our project and so if I disable the intl extension I actually get a conflict because this package tries to re-declare a already polyfilled function.

Hence we can close this as we indeed won't use the package anymore once my change removes it from our project.

Thanks, in any case and cheers from Nextcloud ✌️
