Use import instead of fully qualified namespaces

[rarila]

At least for most cases. Partials left for another PR as they need some more thinking.

All conversions were done carefullly, no tests fail. I hope that no external stuff (Plugins) break.
I don’t know now to review such a monster PR :-(

Fixes #7037

Mind looking into phar issue? See

psalm/.circleci/config.yml

Lines 44 to 49 in e1d1ef3

	- run:
	name: Build Phar file
	command: bin/build-phar.sh
	- run:
	name: Smoke test Phar file
	command: build/psalm.phar --version

for how it's built.

Hmm, we probably should include this in the local tests

@weirdan Fixed. But that was mor an educated guess than knowledge. Do you know what happened there? Doesn’t look wrong to me. Some magic with box that does some search-replace with \Composer\Autoload\ClassLoader perhaps?!

Likely. Should we also revert other similar changes, e.g. in Cli\LanguageServer?

Yes, to be on the save side. The same code is in LanguageServer, Psalter, and Refactor. I guess when it breaks in Psalm it should do so there, too.

Thanks!

@weirdan Found the cause of the \Composer\Autoload\ClassLoader problem:

psalm/scoper.inc.php

Lines 22 to 26 in eb4e9de

	return str_replace(
	'\\'.$prefix.'\Composer\Autoload\ClassLoader',
	'\Composer\Autoload\ClassLoader',
	$contents
	);
