6153: Improve prime_caches and display its progress r=matklad a=jonas-schievink
It now computes the `CrateDefMap` of all crates, which is generally a reasonable approximation for "IDE features ready". There is still some delay after this finishes, I suspect mostly due to impl collection, which takes a while, but this should be an improvement already.
For more accurate progress reports, this topologically sorts all crates before starting this operation. ~~Because that is also the ordering in which parallelization makes sense (which was previously attempted in https://github.com/rust-analyzer/rust-analyzer/pull/3529), I decided to throw that into the mix as well. It still doesn't provide *that* much of a performance boost, but it does scale beyond the current single-core architecture, and adding it was very easy.~~
~~Unfortunately, as written, this will not tell the user which crate is actually causing slowdowns, since the displayed crate is the last one that was *started*, not the one we are currently *blocked* on, but that seems fairly difficult to implement unless I'm missing something.~~
(I have removed rayon for now since it does not work correctly with cancellation.)

6198: Skip macro matcher fragment name semantic highlighting r=matklad a=Veykril
Implements a small state-machine for macro_rules! highlighting to separate out the matcher part of its rules. This skips semantically highlighting names of metavariables in the matcher and expander. This might even allow for more fun macro highlighting things in the future.
Fixes#4380.

6199: Fix `mut self` not emitting mutable binding on `self` use r=matklad a=Veykril
Prior to this, when `self` in a function is taken by value and bound mutably, its use inside of the method body won't be marked `mutably`.
Fixes#5461

5917: Add a command to open docs for the symbol under the cursor r=matklad a=zacps
#### Todo
- [ ] Decide if there should be a default keybind or context menu entry
- [x] Figure out how to get the documentation path for methods and other non-top-level defs
- [x] Design the protocol extension. In future we'll probably want parameters for local/remote documentation URLs, so that should maybe be done in this PR?
- [x] Code organisation
- [x] Tests

5858: Draft: Show reason for failed rename refactoring r=rherrmann a=rherrmann
Return an error with a meaningful message for requests to
`textDocument/rename` if the operation cannot be performed.
Pass errors, raised by rename handling code to the LSP runtime.
As a consequence, the VS Code client shows and logs the request
as if a server-side programming error occured.

I would kindly ask to get feedback from the maintainers if they can spare the time:
* Is the general direction of the proposed changes acceptable?
* I'm new to Rust. The code feels clumsy and redundant, please suggest improvements
if you find the time for. E.g. is there a simple replacement for `RenameError`?
* Should presenting the error with proper severity (i.e. not as a programming error) be part of this change or in a followup change?

6189: adt: correctly inherit field visibility from enum r=jonas-schievink a=jonas-schievink
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.
