internal: convert unwrap to except and add a debug log
Remove an unsafe unwrap that can cause crashes if the value is a `SendError`.
This is my first PR on this repo, please let me know if there is anything I can improve or details I can provide.
Handle `#[cfg]`s on generic parameters
Records attributes on generic parameters in the item tree and filters out generic parameters disabled by `#[cfg]`s in `generic_params_query`.
Closes#11756
Don't provide `generate_default_from_new` when impl self ty is missing
Also don't provide the assist when the `Default` trait can't be found.
Part of #15398
internal: Turn unresolved proc macro expansions into missing expressions
Reduces the amount of type related errors one gets when proc macro expansion is disabled.
fix: Remove unwraps from "Generate delegate trait"
Fixes#15388
This is untested and purely mechanical, maybe some of those `unwrap`s actually made sense, but it probably doesn't hurt to avoid them.
Use the warning color when rust-analyzer is stopped
If the rust-analyzer server isn't running, we can't do much. Treat this state as a warning color, so it's more obvious.
SCIP: Qualify parameters by the containing function
SCIP requires symbols to be unique, but multiple functions may have a parameter with the same name. Qualify parameters according to the containing function.

Set the default status bar action to openLogs
Previously, clicking 'rust-analyzer' would stop the server entirely. This was easy to do accidentally, and then the user has to wait for the server to start up again.

Exclude non-identifier aliases from completion filtering text
When building `CompletionItem`s, this excludes aliases that aren't valid identifiers from the "lookup" text used to filter completions in the LSP client. Including them results in weird completion filtering behavior e.g. `Partial>` matching a completion for the `PartialOrd` trait because it has a doc alias of ">".
Closes#14692
Add ExternCrateDecl to HIR
Adding these doesn't really require much design effort as they represent a single import, unlike use trees which are one item that represent 0 or more imports.
We only resolve to this definition when actually resolving on the name or alias of an `extern crate name as alias` item, not usages yet as that requires far more changes that won't lead anywhere without giving it more thought. Nevertheless the changes slightly improve IDE things, an example being hover on the decl showing the merged doc comments for example.

Added remove unused imports assist
This resolves the most important part of #5131. I needed to make a couple of cosmetic changes to the search infrastructure to do this.
A few open questions:
* Should imports that don't resolve to anything be considered unused? I figured probably not, but it would be a trivial change to make if we want it.
* Is there a cleaner way to make the edits to the use list?
* Is there a cleaner way to get the list of uses that intersect the current selection?
* Is the performance acceptable? When testing this on itself, it takes a good couple seconds to perform the assist.
* Is there a way to hide the rustc diagnostics that overlap with this functionality?
internal: Defer structured snippet rendering to allow escaping snippet bits
Since we know exactly where snippets are, we can transparently escape snippet bits to the exact text edits that need it, and not have to do it for anything other text edits.
Also will eventually fix#11006 once all assists are migrated. This comes as a side-effect of text edits that don't have snippets get marked as having no insert formatting at all.
