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.

When cross compiling macos → dragonfly the dist build fails in the
proc-maro-test-impl crate with the following error:
ld: unknown option: -z\nclang: error: linker command failed with
exit code 1 (use -v to see invocation)
This appears to be a wart stemming from using an Apple host for cross
compiling. Passing the target along to cargo allows it to pick up
a linker that it understands and DTRT.
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.
