6130: Items case quick fix (snake_case / UPPER_SNAKE_CASE / CamelCase) r=matklad a=popzxc
Resolves #4598.
After a third try, it finally works. Boy, it appeared tougher than it seemed.
Initially I thought like "Ha, `rustc` already tells us where idents are named incorrectly. It shouldn't be that hard, should it?".
Well, the problems with the information provided by `rustc` appeared shortly:
- `rustc` warnings are `flycheck` warnings, which are slightly aside from our diagnostics with fixes.
When we map flycheck diagnostic to LSP, we can convert it into a fix, but only if it's marked as `Applicability::MachineApplicable`.
Name case fix is marked `Applicability::MaybeIncorrect`, and for a reason: it only suggest to rename symbol under cursor, without tracking any references.
- Warning spawned by `rustc` are identified by string labels rather than enum. It means that if one day the diagnostic will be renamed in `rustc`, `rust-analyzer` code will still compile, but won't find the required diagnostic by name anymore. If by chance this will happen when some unlucky guy will decide to create their first pull request, they'll be confused by suddenly failing tests (likely) not related to their changes.
- Even if we'll try to build fixes atop of `rustc` warnings, we'll have to do it in the `rust_analyzer::diagnostics::to_proto` module, which is far less
convenient for that matter than `ide` crate.
That's why I decided that it's worth a separate `rust-analyzer` diagnostic, which will implement `DiagnosticWithFix` trait.
After that, I discovered that currently `hir_ty::diagnostics` only check `DefWithBody` types, like function bodies. I had to add support for diagnostics
which look at any `ModuleDef`.
And of course, since I'd added a lot of new functionality, it required extensive testing.
That explains why the diff is so big for a (looking) relatively small feature.
I hope that this PR doesn't only add a small feature, but also creates a base for building another features.
## Example:

P.S. My eyes were bleeding when I had to write the code for the example...
6135: when generating new function, focus on return type instead of body r=matklad a=bnjjj
I made a little change when we use the assist to generate a new function, instead of focusing on the function body, it will focus on return type

Previously, "find all references" on a variant field wouldn't find any
references outside the defining module. This is because variant fields
were incorrectly assumed to be private, like struct fields without
explicit visibility, but they actually inherit the enum's visibility.

6139: Make find_path_prefixed configurable r=matklad a=Veykril
This makes `find_path_prefixed` more configurable allowing one to choose whether it always returns absolute paths, self-prefixed paths or to ignore local imports when building the path.
The config names are just thrown in here, taking better names if they exist :)
This should fix #6131 as well?

6111: Add assist for converting the base of integer literals. r=SomeoneToIgnore a=vlakreeh
This PR adds an assist similar to Intellij's [convert number to](https://i.imgur.com/JH6wstP.png). It also does a small refactor to [assists/src/tests.rs](https://github.com/rust-analyzer/rust-analyzer/blob/fc34403018079ea053f26d0a31b7517053c7dd8c/crates/assists/src/tests.rs) to add the ability to specify the resolved assist for a specific action within an assist group.
## Demo

6019: Remove make::path_from_text r=matklad a=Veykril
This removes the `make::path_from_text` function, which according to a note should've been private. I removed it since it didn't really serve a purpose as it was simply wrapping `make::ast_from_text`.

5989: Rewrite import merging r=jonas-schievink a=Veykril
Rewrites how import merging is being handled. It is now a recursive function to properly handle merging of intermediate levels in the import trees. With this ordering the imports is also now possible tho it doesn't quite order it the same way as `rustfmt` does yet, namely it orders lowercase identifiers after uppercase identifiers as that is the standard character order that rust uses. This also fixes a few weird behaviors that were visible in some of the `replace_qualified_name_with_use.rs` tests.
This really took longer than I was hoping for, fighting with import trees is quite the exhausting task 😅

5955: Remove merge import code duplication r=jonas-schievink a=Veykril
This removes the code duplication caused by #5935, this also allows the assist to merge imports that have equal visibility and prevents merges of unequal visibility. This PR also fixes an iteration mistake in the mentioned PR:
Turns out I made a mistake when writing the `segment_iter` function, I was assuming that the `children` of a path will just be the segments, which is obviously not the case. This also brings insertion order of shorter paths in line with how `rustfmt` orders them.
