* Rename JS concepts
1. Assignment declaration -- an assignment that is treated like a
declaration. Previously called [JS] special (assignment|declaration),
among other things.
2. Expando -- a value that can be used as a target in assignment
declarations. Currently, a class, function or empty object literal.
Functions are allowed in Typescript, too. Previously called a JS
container, JS initializer or expando object.
3. JavaScript -> Javascript. This is annoying to type, and looks like
'Java Script' in a camelCase world.
Everything is a pure rename as far as I know. The only test change is
the API baselines, which reflect the rename from SymbolFlags.JSContainer
to SymbolFlags.Assignment.
* Remove TODO
* Rename Javascript->JS
Note that this introduces a variable name collision in a couple of
places, which I resolved like this:
```ts
const isInJavascript = isInJSFile(node);
```
As `files` always contains declaration files of external libraries, lib files and declaration files from typeRoots, the previous condition evaluated to false for probably all projects out there.
This changes the condition to compare array length after filtering out all declaration files.
That avoids unnecessary work of path normalization in the common case where everything is ok.
Avoids using the TypeChecker when trying to reuse the Program structure.
This allows SourceFiles contained in the old Program to be updated using ts.updateSourceFile
Fixes: #26166
Project references need to be detached from the project when closing project
In SourceMapDecoder handle when the redirected file to project reference is set as the output of the project
Keep configured project alive if project it references has open ref
Fixes#26164
* importFixes: When one file redirects to another, consider both for global import specifiers
* Add test for #26044
* Avoid a symlinked package globally importing itself (fixes another case of #26044)
