Also, not allowing arguments or method calls for autoconfigure. This is a safety
mechanism, since we don't have merging logic. It will allow us to add this in the
future if we want to.
The reason is that parent-child definitions are a different mechanism for "inheritance"
than instanceofConditionas and defaults... creating some edge cases when trying to
figure out which settings "win". For example:
Suppose a child and parent definitions are defined in different YAML files. The
child receives public: false from its _defaults, and the parent receives public: true
from its _defaults. Should the final child definition be public: true (so the parent
overrides the child, even though it only came from _defaults) or public: false (where
the child wins... even though it was only set from its _defaults). Or, if the parent
is explicitly set to public: true, should that override the public: false of the
child (which it got from its _defaults)? On one hand, the parent is being explicitly
set. On the other hand, the child is explicitly in a file settings _defaults public
to false. There's no correct answer.
There are also problems with instanceof. The importance goes:
defaults < instanceof < service definition
But how does parent-child relationships fit into that? If a child has public: false
from an _instanceof, but the parent explicitly sets public: true, which wins? Should
we assume the parent definition wins because it's explicitly set? Or would the
_instanceof win, because that's being explicitly applied to the child definition's
class by an _instanceof that lives in the same file as that class (whereas the parent
definition may live in a different file).
Because of this, @nicolas-grekas and I (we also talked a bit to Fabien) decided that
the complexity was growing too much. The solution is to not allow any of these
new feature to be used by ChildDefinition objects. In other words, when you want some
sort of "inheritance" for your service, you should *either* giving your service a
parent *or* using defaults and instanceof. And instead of silently not applying
defaults and instanceof to child definitions, I think it's better to scream that it's
not supported.

[DI] Introducing autoconfigure: automatic _instanceof configuration

This is a proposal to allow the user to opt into some automatic `_instanceof` config. Suppose I want to auto-tag all of my voters and event subscribers
```yml
# current
services:
_defaults:
autowire: true
_instanceof:
Symfony\Component\Security\Core\Authorization\Voter\VoterInterface:
tags: [security.voter]
Symfony\Component\EventDispatcher\EventSubscriberInterface:
tags: [kernel.event_subscriber]
# services using the above tags
AppBundle\Security\PostVoter: ~
AppBundle\EventListener\CheckRequirementsSubscriber: ~
```
If I'm registering a service with a class that implements `VoterInterface`, when would I ever *not* want that to be tagged with `security.voter`? Here's the proposed code:
```yml
# proposed
services:
_defaults:
autowire: true
autoconfigure: true
# services using the auto_configure_instanceof functionality
AppBundle\Security\PostVoter: ~
AppBundle\EventListener\CheckRequirementsSubscriber: ~
```
The user must opt into this and it only applies locally to this configuration file. It works because each enabled bundle would have the opportunity to add one or more "automatic instanceof" definitions - e.g. SecurityBundle would add the `security.voter` instanceof config, FrameworkBundle would add the `kernel.event_subscriber` instanceof config, etc.
For another example, you can check out the proposed changes to `symfony-demo` - symfony/symfony-demo#483 - the `_instanceof` section is pretty heavy: 81694ac21e/app/config/services.yml (L20)
Thanks!

As spotted by @stof in https://github.com/symfony/symfony/pull/22388#issuecomment-293565243, skipping abstract tagged services removes an opportunity to report config mistakes to users.
Instead of skipping them, let's throw as done before (thus reverting #22039, ping @chalasr).
I made `$container->findTaggedServiceIds()` accept a 2nd arg to make this more systematic.
To keep the possibility to have abstract tagged services *for the purpose of tag inheritance*, `ResolveTagsInheritancePass` now resets their tags.

Enhancing integration test to show that "override" tags show up first

Relates a bit to #22396, in that I'm clarifying and emphasizing the following types of situations:
```yml
services:
_instanceof:
Symfony\Component\Security\Core\Authorization\Voter\VoterInterface:
tags:
# you probably shouldn't set priority here, but let's pretend we did
- { name: security.voter, priority: 100 }
AppBundle\Security\CoolPersonVoter:
tags:
- { name: security.voter, priority: 50 }
```
In the final `Definition`, the tags will appear in this order:
* security.voter, priority 50
* security.voter, priority 100
It works the same for parent-child definitions.
tl;dr; If a service has the same tag multiple times, the one that should be used should appear *earlier* in the Definition. The code already works that way - this test emphasizes it.

Replaces #22294.
The main change is that ChildDefinition does not have "instanceof" applied anymore. All the complexity of the pass came from the merging logic required to deal with them. But in fact, we'd better not have any such logic and just not apply "instanceof" to ChildDefinition (but have them inherit from their parents with the usual logic).

See linked issue for expected DX.
Instead of doing a "continue", let's throw to force the resolution of any ambiguities.
There is a minor potential BC Break, if one uses an ambiguous FQCN as child-definition id in 3.2 or below.
To me, this should be rare, and easy to fix (compile time only).
The DX enhancement this PR provides looks worth it.
> Service definition "App\Foo\Child" has a parent but no class, and its name looks like a FQCN. Either the class is missing or you want to inherit it from the parent service. To resolve this ambiguity, please rename this service to a non-FQCN (e.g. using dots), or create the missing class.

This PR adds a new autowiring mode, based only on the class <> id convention.
This way of autowiring is free from any conflicting behavior, which is what I was looking for to begin with.
The expected DX is a bit more involving than the current way we do autowiring. But it's worth it to me, because it's plain predictable - a lot less "magic" imho.
So in this mode, for each `App\Foo` type hint, a reference to an "App\Foo" service will be created. If no such service exists, an exception will be thrown. To me, this opens a nice DX: when type hinting interfaces (which is the best practice), this will tell you when you need to create the explicit interface <> id mapping that is missing - thus encourage things to be made explicit, but only when required, and gradually, in a way that will favor discoverability by devs.
Of course, this is opt-in, and BC. You'd need to do eg in yaml: `autowire: by_id`.
For consistency, the current mode (`autowire: true`) can be configured using `autowire: by_type`.

[DI] Replace wildcard-based methods autowiring by `@required` annotation

While playing a bit with new features in master around DI configuration, several people around me got bitten by wildcard-based autowiring. The typical example is adding `autowire: [set*]` in `_defaults`: use that on `resource: ../src/Command/` PSR4-based loading and boom, `setApplication` and `setHelperSet` will now be wrongly called. You could tell me "of course, don't to that" - but being bitten so early on a master-only feature makes me really unconfident that this will be easy enough for people after the release.
If wildcard-based autowiring is removed, then I don't see anymore the need for allowing arrays as in `autowire: [setFoo,getBar]`. Moreover, this array syntax has a core DX issue: it's a dead end as far as the learning curve is concerned. You learn it, then when becoming a more advanced dev, someone teaches you that you'd better use another syntax: explicit wiring.
And in fact, we don't need it at all, because something else already exists: just declare a method call, but don't define its arguments. If `autowire: true` is set, then the AutowiringPass already fills in the holes. There is only one tweak required to make this work: don't autowire optional arguments for method calls - or that'd be a BC break. To my PoV that's even better: this makes autowiring fit a "do the minimum to make it work" strategy. A really good one to me.
But there is still an issue: wildcard-based autowiring fits a need. Namely, it allows one to define a convention (eg. `'set*'`), and have all such methods that follow the convention be autowired. To me, this looks like doing it reverse (the DI config should adapt to the code, not reverse). So, to fill this need, let the declaration be in the source: just use an annotation!
This PR adds support for the `@required` annotation, borrowed from the Spring framework:
https://www.tutorialspoint.com/spring/spring_required_annotation.htm
Using the annotation is totally optional of course. If you do, *and if autowiring is on*, then it'll be autowired. If you don't, nothing changes: do manual wiring.
Even when not using autowiring, the annotation is still a nice hint for the consumer of your classes: it tells the reader that this method needs to be called for correct instantiation - thus lowering one drawback of setter injection (discoverability).
The implementation of the annotation parsing is done using a few regexp (no dep on any complex parser) - and works with inheritance, by leveraging the `@inheritdoc` tag (the default behavior being to *not* inherit anything from parent methods).
All in all, looking at the diff stats, it makes everything simpler. Good sign, isn't it?

When a definition is set to be autowired with no method explicitly configured, we already wire the constructor.
We should also autowire abstract getters - with the same reasoning that makes us autowire the constructor: without concrete getters, the class is unusable. This just makes it usable again.

Before we check for circular references, dependencies coming from method calls are not part of the dependency graph. That why the pass is not able to detect circular references like the one described in #19362 during compilation of the container.
If we add another check after all the optimisation passes have been processed, we should be able to detect these circular references too.
