* Allow type-only ImportEqualsDeclarations
* Suppress CJS-in-ESM error when type-only
* Add grammar error on import type in import alias
* Update API baselines
* Fix importsNotUsedAsValues with ImportEqualsDeclarations
* Make bad error talk words more good for Daniel. Fixes#41603
* One more error message baseline update
* Update transformer and emitter
* Remove-all-unused-identifiers skips assigned identifiers
Previously, fixUnusedIdentifier worked the same in fix-all mode as for a
single fix: identifiers with assignments would be deleted:
```ts
function f(a) { }
f(1)
```
becomes
```ts
function f() { }
f()
```
But any kind of argument will be deleted, even one with side effects.
For a single codefix invocation, this is probably OK.
But for fix-all, this could lead to multiple changes
spread throughout a large file.
Now fix-all will only delete parameters and variable declarations with
no assignments:
```ts
function f(a) { }
function g(a) { }
f(1)
g
let x = 1
let y
```
becomes
```
function f(a) { }
function g() { }
f(1)
g
let x = 1
```
* Don't remove assigned parameters for single codefix either
* add optional parameter test case
* Skip initialised params and binding elements
Based on PR feedback from @amcasey
* fixAll removes unused binding patterns completely
* Fixes from comments
Thanks @amcasey for the thorough review
* fix trailing space lint
* correctly remove-all array binding
* Unuse Identifier codefix understands constructors
Previously, it did not look for `super()` and `new this()` calls when
determining whether a constructor parameter could be deleted.
* better names, fix off-by-1 bug
* Codefix understands super methods now too
This unifies the code, changing it considerably.
* Add tracing support to tsserver
Read the `TSS_TRACE` environment variable to determine which directory
trace files should be written to.
Notable changes from tsc tracing:
1) Drop all tracepoints that depend on type IDs
2) Write output to trace.PID.json
3) New, server-specific events (request/response, cancellation, etc)
* Drop try-finally blocks that aren't strictly necessary
* Fix lint error
* Trace background work (for diagnostics)
* Move try-finally blocks into session so tsc doesn't use them
* Add missing try-finally
* Use consistent capitalization
* Inline canPop call where underlying variable is available
* Clarify comments
* Include PID in build-mode file names
* Introduce more efficient popAll function
* Trace throwIfCancellationRequested rather than isCancellationRequested
* Remove unnecessary try-finally blocks
* Add a command-line argument for consistency with logging
* Fix rebase issues
* Address PR feedback
* Rename completionEvents to eventStack
* Drop assertStackEmpty as hard-to-maintain and marginally valuable
* Rename stepCancellation to stepCanceledEarly
* Rename stepEarlyCancellation to stepCanceled and use flag instead
* Check correct variable on exit
* add basicly support for rename string literal type
* fix merge conflict
* fix some behavior
* Update package-lock.json
* Update package-lock.json
* do not break old behavior if not type checked
* fix cr issue

* Modify test case to reproduce error
* Fix TypeOnlyExport codefix to work with 3 or more type exports in the same declaration
The check to ensure that a fixed export declaration wasn't fixed again
was reversed. This only surfaced when 3 or more type exports existed in
the same declaration.
* Add failing test cases for comments being duplicated
* Fix convertToTypeOnlyExport codefix from duplicating leading comments
* Simplify convertToTypeOnlyExport when change is just inserting `type` keyword

* Fix default-property-assignment decls+prototype property decls
The check in getAssignedClassSymbol forgot to allow for default-property
assignment declarations, in part because it wasn't using a utility
function to do so.
* small cleanup
* make allowDeclaration parameter required
