7102: Fix completion of Default struct update syntax r=Veykril a=nick96
Previously the inserted text was always `..Default::default()` which ends up as `...Default::default()`
if `.` was typed. Now checks if the current token is `.` and inserts `.Default::default()`
if it is, so `..Default::default()` is correctly completed.
I think there's probably a better way to implement this context aware completion because I've seen it in other parts of rust-analyzer as a user but I'm not sure how to do it.

7071: Pass --all-targets to "cargo check" when discovering external resources r=matklad a=WasabiFan
There is a repro case and background in the linked issue.
In short, the goal of this MR is to allow rust-analyzer to discover proc-macros which come from your tests (including, most importantly, dev-dependencies).
By default, `cargo check` implies the equivalent of `--lib --bins`, meaning it'll check your libraries and binaries -- but not tests! This means proc-macros (or, I guess, build scripts as well) weren't discovered by rust-analyzer if they came from tests.
One solution would be to manually add `--lib --bins --tests` (i.e., just augment the effective options to include tests). However, in this MR, I threw in `--all-targets`, which [according to the docs](https://doc.rust-lang.org/cargo/commands/cargo-check.html#target-selection) implies `--benches --examples` too. I have absolutely no idea what repercussions that will have on rust-analyzer for other projects, nor do I know if it's a problem that build scripts will now be discovered for tests/examples/benches. But I am not aware of a reason you _wouldn't_ want to discover these things in your examples too.
I think the main drawback of this change is that it will likely slow down the `cargo check`. At a minimum, it'll now be checking your tests _and_ their dependencies. The `cargo check` docs also say that including `--tests` as I have here may cause your lib crate to be built _twice_, once for the normal target and again for unit tests. My reading of that caveat suggests that "building twice" means it's built once for the tests _inside_ your lib, with a test profile, and again for any consumers of your lib, now using a normal release profile or similar. This doesn't seem surprising.
Very minor caveat: `--tests` will not include tests within a binary if it has `test = false` set in `Cargo.toml`. (I discovered this manually by trial-and-error, but hey, it actually says that in the docs!) This is likely not an issue, but _does_ mean that if you are -- for whatever reason -- disabling tests like that and then manually specifying `cargo test --package <...> --bin <...>` to run them, rust-analyzer will remain unaware of proc-macros in your tests.
I have confirmed this fixes the original issue in my sandbox example linked in #7034 and in my own project in which I originally discovered this. I've left it configured as my default RA language server and will report back if I notice any unexpected side-effects.
Fixes#7034

In an attempt to fix#6052 and #4249 this attempts to detect
if rustfmt is a rustup proxy which isn't installed, and reports
the error message to the user for them to fix.
In theory this ought to be memoised but for now it'll do as-is.
Future work might be to ask the user if they would like us to
trigger the installation (if possible).

7064: Ignore qualifiers when doing autoimport completions lookup r=lnicola a=SomeoneToIgnore
A follow-up of https://github.com/rust-analyzer/rust-analyzer/pull/6918#issuecomment-748511151 and the PR itself.
Tweaks the `import_map` query api to be more flexible with the ways to match against the import path and now fuzzy imports search in names only.
This had improved the completion speed for me locally in ~5 times for `fuzzy_completion` span time, but please recheck me here.
IMO we're fast and presice enough now, so I've added the modules back to the fuzzy search output.
Also tweaks the the expect tests to display functions explicitly, to avoid confusing "duplicate" results.

https://github.com/rust-lang/rust/pull/75082 and https://github.com/rust-lang/rust/pull/76292 added a new flag in `proc_macro::Bridge` such that the ABI was changed. These ABI changing are the reason of some weird panics which caused #6880 and maybe related to the panic mentioned in #6820.
These changes are landed on rust stable 1.48 so I think it is okay to apply it now.

Assist vs UnresolvedAssist split doesn't really pull its weight. This
is especially bad if we want to include `Assist` as a field of
diagnostics, where we'd have to make the thing generic.

Avoid mutation of snapshot's config -- that's spooky action at a
distance. Instead, copy it over to a local variable.
This points out a minor architecture problem, which we won't fix right
away.
Various `ide`-level config structs, like `AssistConfig`, are geared
towards one-shot use when calling a specific methods. On the other
hand, the large `Config` struct in `rust-analyzer` is a long-term
config store.
The fact that `Config` stores `AssistConfig` is accidental -- a better
design would probably be to just store `ConfigData` inside `Config`
and create various `Config`s on the fly out of it.

I'm not sure if this is totally correct, it looks like we create **two** `EagerCallLoc`s per macro invocation, one for the arguments (?), and one for the actual macro call. I gave both the same `AstId`, hopefully that's correct.

6964: Add full pattern completions for Struct and Variant patterns r=matklad a=Veykril
Just gonna call it full pattern completion as pattern completion is already implemented in a sense by showing idents in pattern position. What this does is basically complete struct and variant patterns where applicable(function params, let statements and refutable pattern locations).
This does not replace just completing the corresponding idents of the structs and variants, instead two completions are shown for these, a completion for the ident itself and a completion for the pattern(if the pattern make sense to be used that is). I figured in some cases one would rather type out the pattern manually if it has a lot of fields but you only care about one since this completion would cause one more work in the end since you would have to delete all the extra matched fields again.
These completions are tagged as `CompletionKind::Snippet`, not sure if that is the right one here.

6921: Higher-ranked trait bounds for where clauses r=flodiebold a=Veykril
There is a slight problem with this which is also noted in a FIXME now but `LifetimeParameters` of these ForLifetime where clauses allocate the lifetimes in the corresponding arena as if they were lifetimes of the item itself and not just the clause they belong to. I wasn't entirely sure what I could do about this but given nothing really uses lifetimes like that currently I figured it might be fine? Open to suggestions for that problem.

6901: Temp fixes panic caused by no ast for proc-macro r=maklad a=edwin0cheng
There are some panic when hover/goto definition for proc-macro. It is because in current design, we don't have `ast-node` for proc-macro and then it trigger [this](479d1f7eec/crates/hir/src/has_source.rs (L116)) line to panic.

We used to have `Def` suffix for all symbols, but we moved off from
that. `FunctionDef` isn't better than `Function`. Looks like we've
forgot to change `Impl` though!
6907: Lifetime reference search r=matklad a=Veykril
PR #6787 but rewritten to make use of the HIR now. This only applies to Lifetimes, not labels. Also Higher-Ranked Trait Bounds aren't supported yet, but I feel like this PR is big enough as is which is why I left them out after noticing I forgot about them.
Supporting renaming required slight changes in the renaming module as lifetime names aren't allowed for anything but lifetimes(and labels) and vice versa for normal names.

ItemTree is per-file, so there is no unique crate associated with it.
This means that it cannot know the active CfgOptions and thus couldn't
handle `cfg_attr`.
Prepare it for `cfg_attr`s by avoiding accessing attributes.
