866: Implement basic support for Associated Methods r=flodiebold a=vipentti
This is my attempt at learning to understand how the type inference works by adding basic support for associated methods. Currently it does not resolve associated types or constants.
The basic idea is that `Resolver::resolve_path` returns a new `PathResult` type, which has two variants, `FullyResolved` and `PartiallyResolved`, fully resolved matches the previous behavior, where as `PartiallyResolved` contains the `PerNs<Resolution` in addition to a `segment_index` which contains the index of the segment which we failed to resolve. This index can then be used to continue inference in `infer_path_expr` using the `Type` we managed to resolve.
This changes some of the previous apis, so looking for feedback and suggestions.
This should enable fixing #832

This also adds new pub(crate) resolve_path_segments which returns the
PathResult, which may or may not be fully resolved. PathResult is also now
pub(crate) since it is an implementation detail.
864: Fix handling of generics in tuple variants and refactor a bit r=matklad a=flodiebold
(The problem was that we created separate substitutions for the return value, so we lost the connection between the type arguments in the constructor call and the type arguments of the result.)
Also make them display a tiny bit nicer.
Fixes#860.

876: Fix join_lines not adding a comma after join_single_expr_block with match arm r=matklad a=vipentti
Fixes#868
Co-authored-by: Ville Penttinen <villem.penttinen@gmail.com>
We will also remove optional whitespace between the expression and the comma.
e.g.
```rust
fn foo() {
let x = (<|>{
4
} ,); // NOTE: whitespace
}
```
becomes
```rust
fn foo() {
let x = (<|>4,);
}
```
This is done in `infer_path_expr`. When `Resolver::resolve_path` returns
`PartiallyResolved`, we use the returned `Resolution` together with the given
`segment_index` to check if we can find something matching the segment at
segment_index in the impls for that particular type.
Benchmarks show no difference. This is probably because we are
bottlenecked on memory allocations, and we should fix that, but we are
not optimizing for performance just yet.

846: WIP: Enable parsing of attributes inside a match block r=matklad a=vipentti
We allow invalid inner attributes to be parsed, e.g. inner attributes that are
not directly after the opening brace of the match block.
Instead we run validation on `MatchArmList` to allow better reporting of errors.
This fixes#845 and works towards #759

844: Refactor find_all_refs to return ReferenceSearchResult r=vipentti a=vipentti
This refactors `find_all_refs` to return a new `ReferenceSearchResult` based on feedback in #839.
There are few questions/notes regarding the refactor:
1. Introducing `NavigationTarget::from_bind_pat` this simply forwards the call to `NavigationTarget::from_named`, could we just expose `from_named` directly as `pub(crate)` ?
2. Added an utility method `NavigationTarget::range` since there were few places where you would use `self.focus_range.unwrap_or(self.full_range)`
3. Implementing `IntoIterator` for `ReferenceSearchResult`. This turns `ReferenceSearchResult` into an iterator over `FileRanges` and allows previous code to mostly stay as it was based on the order that `find_all_refs` previously had (declaration first and then the references). I'm not sure if there is a way of doing the conversion to `IntoIter` without the allocation of a new vector
4. Is it possible to have a binding without a name? I'm not sure if the `NavigationTarget::from_bind_pat` can cause some edge-cases that previously were ok
This fixes#835.

This makes it more like the other code model types.
Also make Module::definition_source/declaration_source return HirFileIds, to
make them more like the other source functions.

Namely, the allowance for up to 7 events, and thus requiring anyone
with fewer than 7 events to wait for the 3 second timeout, is only
relevant to fsevents (i.e. Mac OS X)
830: Fix test_vfs_works failing on Windows due to extra Write events r=pnkfelix a=vipentti
On Windows `notify` generates extra `Write` events for folders, which caused
`process_tasks` to not handle all tasks generated on Windows.
This fixes#827

Instead of using canonicalize, we now join the given path to
`std::env::current_dir()`, which either replaces the path, if the given path is
absolute, or joins the paths.
This fixes#821.
818: In `RootConfig::contains`, check against canonicalized version of root path r=matklad a=pnkfelix
In `RootConfig::contains`, check against canonicalized version of root path since OS may hand us data that uses the canonical form rather than the root as specified by the user.
This is a step towards a resolution of issue #734 but does not completely fix the problem there.

813: Add support for container_name in workspace/symbol query r=matklad a=vipentti
Currently this does not fill in the container_info if a type is defined on the top level in a file.
e.g. `foo.rs`
```rust
enum Foo { }
```
`Foo` will have None as the container_name, however
```rust
mod foo_mod {
enum Foo { }
}
```
`Foo` has `foo_mod` as the container_name.
This closes#559
