`cargo rustc -- <args>` first builds dependencies then calls `rustc <args>` for the current package. Here, we don't want to build dependencies, we just want to call `rustc --print`. An unstable `cargo rustc` `--print` command bypasses building dependencies first. This speeds up execution of this code path and ensures RA doesn't recompile dependencies with the `RUSTC_BOOTSRAP=1` env var flag set.
Note that we must pass `-Z unstable-options` twice, first to enable the `cargo` unstable `--print` flag, then later to enable the unstable `rustc` `target-spec-json` print request.
Some packages (e.g. thiserror) force a recompile if the value of the `RUSTC_BOOTSTRAP` env var changes. RA sets the variable to 1 in order to enable rustc / cargo unstable options it uses. This causes flapping recompiles when building outside of RA.
As of Cargo 1.75 the `--keep-going` flag is stable. This change uses the flag without `RUSTC_BOOTSTRAP` if the Cargo version is >= 1.75, and drops `--keep-going` otherwise. This fixes build script recompilation.
fix: Fix build scripts not being rebuilt in some occasions
Also makes proc-macro changed flag setting async, we don't wanna block `process_changes` on the database as that is on the main thread!
This commit also adds `tracing` to NotificationDispatcher/RequestDispatcher,
bumps `rust-analyzer-salsa` to 0.17.0-pre.6, `always-assert` to 0.2, and
removes the homegrown `hprof` implementation in favor of a vendored
tracing-span-tree.
Give a userful error when rustc cannot be found in explicit sysroot
Somehow r-a believed that my sysroot was something weird with no rustc. Probably a me issue, but it was impossible to diagnose since r-a just gave me a plain "No such file or directory". Adding this error makes it clear what happened and allows diagnosing the problem.

fix: Update metavariable expression implementation

This duplicates behavior of that before and after PR https://github.com/rust-lang/rust/pull/117050 based on the toolchain version. There are some 1.76 nightlies that are still broken (any before that PR basically) but fetching and storing the commit makes little sense to me (opposed to the toolchain version).
Make data reflect a case where dev deps are existent.
base-db::CrateGraph::extend now adds dev dependencies for a crate
in case of its upgrading from a CrateOrigin::Lib kind of a crate to a
CrateOrigin::Local one.
Partially fixes#15656 . When a crate graph is extended which is the case when new workspaces are added to the project
the rules for deduplication were too strict. One problem that arises from this is that in certain conditions
when we see the same crate having different `CrateOrigin`s the first form would be maintained. This approach however
results in some unwanted results such as making renaming forbidden as this has been recently only made available for
local crates. The given example in #15656 can still not be resolved with this PR as that involves taking inconsistencies
between dependencies into consideration. This will be addressed in a future PR.
