924: Improve show syntax tree r=matklad a=vipentti
This implements some of the features discussed in #820.
You can now select a range of syntax in a file and then use "Show Syntax Tree" to show its syntax. In addition you can select a range of syntax that is inside a string (typically test cases) and show its syntax as well.
Previous behavior is still available, simply use "Show Syntax Tree" without a selection, and you get the live updating syntax tree. Additionally now the live updating tree will update when the active file is changed. Previously you had to type something in the new file to get the syntax tree to update.

We simply remove all the CUSTOM_MARKERS before attempting to parse the file.
This allows for the syntax selection to work with most of the test strings.
This allows us to select a string or portions of it and try parsing it as rust
syntax. This is mostly helpful when developing tests where the test
itself contains some rust syntax as a string.
Previously when using the file based syntax tree, it would not update until a
change had been made in the new file. Now we automatically update the syntax
tree to match the current file.
This enables the client to use a command to either show the live-updating
version of the syntax tree for the current file. Or optionally when a selected
range is provided, we then provide a snapshot of the syntax tree for the range.
917: Trait tests r=flodiebold a=flodiebold
This adds a bunch of basic tests for trait functionality, just to outline what seems like the first goals for that ;)
It also changes the display of `Ty::Unknown` to `{unknown}`, since `[unknown]` could be confused with a slice, and fixes an error in the emacs runnables code.

908: Enable markup for hover on expressions which resolve using type_of r=matklad a=vipentti
This adds highlighting when hovering over items which are resolved using
`type_of`.
This adds basic highlighting, discussed in #904.

915: Bring BodySyntaxMapping in line with other source-map instances r=flodiebold a=matklad
* rename to SourceMap
* don't store the actual body inline, just return a pair

906: Add support for goto definition and hover for struct fields r=matklad a=vipentti
This works partially towards fixing #512

900: Add new trait ast::TypeAscriptionOwner r=vipentti a=vipentti
This trait should be implemented for nodes which have an ascribed type,
e.g. thing : Type. Such as let, const, static, param, named struct fields.
In addition, we update some places where previously we used node + node.type_ref() with `TypeAscriptionOwner` in the trait bounds.

901: Add basic support for showing fn signature when hovering r=matklad a=vipentti
This adds basic support for displaying function signature when hovering over a usage of a function.
Additionally refactored `hover` to return `HoverResult` to ease with testing and in general to be more robust.
