refactor: remove deprecations in HTTP [WIP]

[paulbalandan]

Description
Sending this early to get the #10000 slot. 😂

This is not yet complete, but initially there are quite breaking changes:

• Removed the deprecated assumption that URIs with the same host as baseURL should be relative to the project's configuration (deprecated by Internal URI handling #4646 and reinforced in fix: forceGlobalSecureRequests break URI schemes other than HTTP #5730)
• URI::setSilent() is removed, meaning it will always throw exceptions on invalid URIs instead of continuing.

Checklist:

• Securely signed commits
• Component(s) with PHPDoc blocks, only if necessary or adds value (without duplication)
• Unit testing, with >80% coverage
• User guide updated
• Conforms to style guide

Haha, love the dedication 😆

I'm a little concerned about removing URI::setSilent(). Given how commonly it's used, this might be more disruptive than expected.

The deprecation was made in #7252 , mainly because it's not in PSR-7. Do you mean to "un-deprecate" it?

[michalsn]

Well, the reason in the comment ("Method not in PSR-7") isn't very fortunate, because PSR-7 allows extra methods.

The real problem is immutability and hidden behavioral state.

Since setSilent() has existed for a long time and occasionally comes up on Slack, I would prefer postponing removal until v5 to avoid unnecessary complaints.

Okay, I'll retain it and add a hard deprecation notice on it. For the *Silent tests, are you fine with removing them though?

[michalsn]

Yes, thank you!
