Remove the ability to configure the user config path
Being able to do this makes little sense as this is effectively a cyclic dependency (and we do not want to fixpoint this really).
Priming caches is a performance win, but it takes a lock on the salsa
database and prevents rust-analyzer from responding to e.g. go-to-def
requests.
This causes confusion for users, who see the spinner next to
rust-analyzer in the VS Code footer stop, so they start attempting to
navigate their code.
Instead, set the `quiescent` status in LSP to false during cache
priming, so the VS Code spinner persists until we can respond to any
LSP request.
These flags were added to help rust-analyzer integrate with repos
requiring non-Cargo invocations. The consensus is that having two
independent settings are no longer needed. This change removes
`invocationLocation` in favor of `invocationStrategy` and changes
the internal representation of `InvocationStrategy::Once` to hold
the workspace root.
Add scip/lsif flag to exclude vendored libaries
#17809 changed StaticIndex to include vendored libraries. This PR adds a flag to disable that behavior.
At work, our monorepo has too many rust targets to index all at once, so we split them up into several shards. Since all of our libraries are vendored, if rust-analyzer includes them, sharding no longer has much benefit, because every shard will have to index the entire transitive dependency graphs of all of its targets. We get around the issue presented in #17809 because some other shard will index the libraries directly.
fix: Properly account for editions in names
This PR touches a lot of parts. But the main changes are changing `hir_expand::Name` to be raw edition-dependently and only when necessary (unrelated to how the user originally wrote the identifier), and changing `is_keyword()` and `is_raw_identifier()` to be edition-aware (this was done in #17896, but the FIXMEs were fixed here).
It is possible that I missed some cases, but most IDE parts should properly escape (or not escape) identifiers now.
The rules of thumb are:
- If we show the identifier to the user, its rawness should be determined by the edition of the edited crate. This is nice for IDE features, but really important for changes we insert to the source code.
- For tests, I chose `Edition::CURRENT` (so we only have to (maybe) update tests when an edition becomes stable, to avoid churn).
- For debugging tools (helper methods and logs), I used `Edition::LATEST`.
Reviewing notes:
This is a really big PR but most of it is mechanical translation. I changed `Name` displayers to require an edition, and followed the compiler errors. Most methods just propagate the edition requirement. The interesting cases are mostly in `ide-assists`, as sometimes the correct crate to fetch the edition from requires awareness (there may be two). `ide-completions` and `ide-diagnostics` were solved pretty easily by introducing an edition field to their context. `ide` contains many features, for most of them it was propagated to the top level function and there the edition was fetched based on the file.
I also fixed all FIXMEs from #17896. Some required introducing an edition parameter (usually not for many methods after the changes to `Name`), some were changed to a new method `is_any_identifier()` because they really want any possible keyword.
Fixes#17895.
Fixes#17774.

Assuming it isn't cancelled. Closes#17902.
The only place CommandHandle::join is used is when the flycheck command
finishes, so this commit changes the behavior of the method itself.
internal: Reply to requests with defaults when vfs is still loading
There is no reason for us to hit the database with queries when we certainly haven't reached a stable state yet. Instead we just reply with default request results until we are in a state where we can do meaningful work. This should save us from wasting resources while starting up at worst, and at best save us from creating query and interning entries that are non-meaningful which ultimately just end up wasting memory.
internal: Optimize the usage of channel senders
Used `Sender` directly instead of a boxed closure. There is no need to use the boxed closure. This also allows the caller to decide to do something other than `unwrap` (not a fan of it BTW).
Include vendored crates in StaticIndex
`StaticIndex::compute` filters out modules from libraries. This makes an exceptions for vendored libraries, ie libraries actually defined inside the workspace being indexed.
This aims to solve https://bugzilla.mozilla.org/show_bug.cgi?id=1846041 In general StaticIndex is meant for code browsers, which likely want to index all visible source files.

internal: Load VFS config changes in parallel
Simple attempt to make some progress f or https://github.com/rust-lang/rust-analyzer/issues/17373
No clue if those atomic orderings are right, though I don't think they are really too relevant either.
A more complete fix would probably need to replace our `ProjectFolders` handling a bit.
